Deciphering the Costs of Reproduction in Mango – Vegetative Growth Matters

Effect of nitrates alone or with paclobutrazol on flowering induction and production in mango cv. Tommy Atkins. Adriana Contreras-Oliva 2.

Postal No. Ciencia de los Alimentos. The flowering induction in mango Mangifera indica L. The objective of this research was to evaluate the effect of potassium PN , ammonium nitrate AN and paclobutrazol PBZ on flowering induction and fruit production in mango cv. An increase on fruit weight and size reduction was observed at harvest. PBZ followed by foliar application of nitrates induced flowering and enhanced the number developed panicles in mango cv.

Mango Mangifera indica L.The total world fruit production in wasMexico ranks the fifth place contributing with the 3. It also influences the quality and quantity of fruits Tiwari et al.

The flowering in mango has distinct behavior in the tropical regions compared with the subtropical regions. For instance, in the subtropical regions mango flowering is given in response to cool temperature exposure Sukhvibul et al. Floral induction has been intensively studied in mango, more under subtropical than under tropical environments Guevara et al. Flowering induction in mango orchards is an agricultural practice carried out on tropical conditions to obtain fruits out-of-season and reach better sale prices.

The induction substances regularly applied are potassium nitrate PN Quijada et al. Several researches have shown that chemical substances are capable to induce flowering in mango.

Yeshitela et al. Amrapali Sarker and Rahim,Moreover, foliar application of potassium nitrate stimulates flowering in sufficiently mature stems Afiqah et al. The application of nitrate to induce flowering is also complemented by plant growth regulators PGR.

One of this PGR is paclobutrazol PBZ , a gibberellin synthesis inhibitor, used to effectively control plant vigor and to promote flowering shoots in mango Kishore et al. PBZ not only stimulates flowering but also can improve mango yield and quality Kishore et al.

However, Narvariya et al. Discrepancies observed in research results seem to be related to different environmental conditions, geographical zone, cultivar, dose, application interval and age of flush.

Also, little information about the effect of nitrates and PBZ application on the flowering induction and production is documented in the tropical region of Mexican southern. Thus, the application of PBZ followed by potassium and ammonium nitrate could induce early flowering and improve fruit production in mango cv. This study was conducted on mango cv.The plants were seven years old and planted at distance of 10x10m without irrigation, and prevalent disease and pest management were followed according to agronomic management recommended for the region.

The experimental design was a completely random. The experimental unit was integrated by two mango trees and each treatment assessed in triplicate. First, a representative random sampling of tree canopy diameter was carried out in order to calculate an average of canopy diameter it was obtained a tree canopy diameter of 3. The dose of PBZ was applied once when soil was at field capacity, at a concentration of 1 g of a. The aqueous solution was prepared using 3.

Both nitrates were applied twice; the first one on September 16 and the second one on September 21,These treatments were applied with a power backpack sprayer ensuring a homogenous application over the mango tree foliage until the solutions run-off. When the inflorescence emerged, days to flowering d and panicle number were recorded. Days to flowering were obtained counting the days elapse after the last application of nitrate to blooming beginning.

Panicle number were registered each seven days at morning since the first panicle was observed, quantifying the total number of panicles per tree.

Fifteen panicles were tagged on each mango tree at chest height distributed uniformly around the mango tree. The fruits from the tagged panicles were harvested days after the flowering and transported immediately to the Food Laboratory at Colegio de Postgraduados Campus Tabasco for the assessment of the production variables. Before measuring the production variables, the fruit was washed with tap water to remove mango sap and dust, selected, randomized and then air-dried at room temperature.

Twenty mangoes randomly selected from the harvested fruit of each treatment were used to determine fruit weight and size equatorial and polar diameter. SA , respectively.Effect of nitrates alone or with PBZ on the floral induction and panicle development. Table 1 Effect of nitrates alone or with paclobutrazol on the flowering induction of mango cv. Tommy Atkins at Oaxaca, Mexico. Tabla 1. In contrast, Yeshitela et al. In addition, Maloba et al.

Table 2 Effect of nitrates alone or with paclobutrazol on the number of developed panicles on mango cv. Tabla 2. These results are in agreement with those obtained by Oosthuyse who reported a similar effect on plants treated with PBZ plus PN in mango cv. Likewise, paclobutrazol soil application at 1. Also these same results in this study, were similar to those revealed by Rebolledo-Martinez et al.

Manila in tropical conditions of Nayarit Mexico and 37 days respect to the natural flowering in cv. Manila, respectively. It is known that nitrates have action on the bud dormancy breaking Ionescu et al. Also, it is generally believed that PBZ is a gibberellin inhibitor reducing the vegetative promoter level and thus stimulates flowering shoots of fruit crops Guevara et al.

Likewise, more recent studies revealed that mango flowering coincides with increase in nonenzymatic and enzymatic antioxidant activities, and a high antioxidant status induced by paclobutrazol is responsible for its floral responses Bindu et al. Potassium nitrate stimulates early flowering and increase number of panicles in trees growing in tropical and subtropical regions Tiwari et al.

The efficacy of flowering inducing chemicals is dependent on several factors including mango variety, dose, time of application and stage of development, among others. In this research the PBZ treatment applied alone did not shorten the period for the beginning of flowering on Tommy Atkins mango with respect to the control treatment Table 1.

Our results are in agreement with other researcher. For instance, soil application of PBZ to 3 mL m -1 canopy diameter did not significantly affect the floral inductionRaspuri Srilatha et al.Moreover, several treatments with PBZ applied in soil drencher did not induce flowering in mango cv. Dashehari Narvariya et al. Conversely, treatments of PBZ caused earlier panicle emergence in mango cv. Rosa and Alphonso compared with control treatment Shinde et al.

Tommy Atkins who conclude that fruit weight decrease as PBZ concentration increase, they interpret this fact as due to fruit overcrowding resulting in more competition for the available resources.

These effects are also reported in other horticultural crops as cucumber, tomatoes and avocado Magnitskiy et al. Although in mango cv. Figure 2 Effect of ammonium nitrate alone or with paclobutrazol on the weight and size of mango fruit cv.

Figura 2.Another fact in this research is that the bigger weight and size of fruit from the non-induced plant could be attributed to the water supply by rainfall and solar radiation on the period of fruit development on the trees concurring with the rainy season from the region Spreer et al. This long-lived tree is well adapted to a wide range of tropical and subtropical environments. In the low-latitude tropics, flowering is initiated after a period of water stress at least six weeks durationEven though the fruit weight was affected negatively by several flowering inducer treatments, fruit were in the acceptance category of the required by the Mexican norms of mango fruit quality.

PBZ followed by foliar application of nitrates, induced flowering and enhanced the number developed panicles and it might be used as an alternative to induce flowering of mango trees cv.

Thanks to Mr. Antonio Castillo Castillejos, owner of the mango orchard where this study was performed.


Flowering induction in mango tree: updates, perspectives and options for organic agriculture. ABSTRACT: The artificial flowering induction in mango tree is the most important crop management in mango orchards and requires greater attention from growers. The management involves three steps: stoppage of plant growth, branch maturation and flowering induction with nitrates. The first stage starts with the application of paclobutrazol to the soil. However, problems with the use of excessive concentrations are common and lead to the accumulation of residues in the soil.

How to Grow Your Mango Fruit Tree Business in the Philippines

Mango is an evergreen tree and belongs to the family of Anacardiaceae. This tree has a thick trunk and the leaves are shiny and dark green. The flowers of the tree have cream-pink petals. The mango fruit has an oval shape with soft yellow flesh. The color of the skin of the fruit is found in yellow, green, and even red color. The height of the tree can be 45 meters. If you grow mango trees in your garden, you will get fruit and shade in your garden on hot summer days. A healthy mango tree in a suitable climate and location can produce juicy mangoes per year. Some varieties bear fruit every year and some in alternate years. If the age of the mango tree is about 10 years it may produce fruit in alternate years.

Israel: flowering induction in mango

Reinerio Makinano for and in behalf of Governor Art C. Makinano said that Bohol needs more mango fruit production to answer the demand of the growing population of the Boholanos and the influx of tourists who have come in the province being a tourist destination. He said the PGBh under the Yap and Relampagos administration has been looking forward to expand or sustain the mango industry in the province, thus these projects have been established by undergoing rehabilitation of the mango trees aging through pruning, applying organic fertilizer and flower inducer. MGSPA pres. Anga thanked the PGBh for giving them the inputs to include the technology on how to grow mango trees.

Stable mango yields: timing is everything

Visit Us Contact Us. And over one million metric tonnes of them were harvested in the Philippines last year. But it was not ever thus. The prolific mango production in the Philippines is due in large measure to the ingenuity of one man. Forty years ago, Filipino horticulturalist, Dr. Ramon Barba developed a simple method for inducing early flowering in mango plants.

Calcium for mango trees

Jump to navigation Skip to Content.Mango flowers form from terminal buds of the most recent mature shoots. Most varieties flower once a year during winter or spring following a dormant period. Flower initiation is usually triggered by cool nights and dry conditions. The most commonly grown mango variety in WA, Kensington Pride, is known to suffer from inconsistent flowering and irregular bearing, especially in climates with a short dormant period. The growth regulating chemical paclobutrazol used by conventional growers to promote flowering is not permitted under organic systems.

My research on mango flowering began about stored in locations throughout the tree to be used likely have different thresholds of induction. At.

Off-Season flower induction technologies for enhanced Production of Mango

When the canopies of mango trees overlap, the trees are usually cut down. This is because old trees with overlapping canopies are not very productive. They respond poorly to flower induction. Few flowers develop into fruits.

How to Get a Mango Tree to Get Blossoms

The quantitative floral inductive role of the age of the last vegetative flush was investigated in replicated trials of two cultivars of mango Mangifera indica L.Empirical observations have indicated that stems must be in rest for sufficient time, generally 4 to 5 months, to be induced to flower in the absence of cool temperatures. Twelve trees per cultivar were tip-pruned to stimulate a synchronous flush of vegetative growth at the beginning of the experiments. Biweekly sprays continued in this first set until a growth response was observed, whereupon the set was retired from further observations, and the second set of three synchronized trees began receiving biweekly spray treatments until they initiated a growth flush. The schedule continued through the four successive sets of trees until the age of stems necessary to induce a flowering response was determined. None of the non-treated orchard trees flowered during this time. Stem age was the key factor correlated with flowering.

MANGO TIP: Don’t Spray Mango Flowers with Pesticide When In Full Bloom

Many varieties of mango trees naturally produce fruit every other year; during the "off" year, the crop may be very small or even nonexistent. The use of flower inducers stimulates flower growth during the resting year so the tree produces annually. Flower inducers can also increase the number of viable blooms during the natural fruit-producing year, for an increase in production; they can also be used on varieties that provide a crop every year, to boost harvest.
