“…Increased fruit yield owing to paclobutrazol treatment was due to increased number of flowering shoots and reduced vegetative / dormant shoots, compared to the control. This is in line with the work done by Burondkar et al [22]. Tandel and Patel [23] reported that application of paclobutrazol increased the yield in all cultivars viz., Alphonso, Kesar and Rajapuri.…”

Flowering is the first of several events that lay the foundation for mango production every year. The temperatures below 15°C readily promote floral induction. Decrease in temperature below 20 0C is common in sub-tropical regions but seldom occurs in many tropical ones. So, an alternative strategy for optimum flower initiation under tropical condition is essentially required for increasing the productivity of plant. Among different strategies evolved, paclobutrazol and potassium nitrate application is effective not only in flower induction but also in early and offseason flower production in mango. Hence, an experiment was conducted to study the effect of paclobutrazol and potassium nitrate on the flowering, fruit yield and quality of Amrapali mango (Mangifera indica L.) plants grown under different plant spacings at Horticultural Research Station, OUAT, Bhubaneswar during 2018-19 and 2019-20. The experiment was laid out in a Factorial Randomized Block Design with 24 treatment combinations and 2 replications. The treatment combinations consist of four levels of spacings (2.0 x 2.0 m, 4.0 x 2.0 m, 4.0 x 4.0 m, 8.0 x 2.0 m) and 6 levels of chemical treatments (Paclobutrazol@0.25, 0.50 and 0.75 g a.i. per meter of canopy spread and KNO3@ 2% and 4%) and a control with water application. The results revealed that plants spaced at 4.0 x 4.0 m with application of paclobutrazol 0.50 g a.i. recorded maximum flowering intensity (82.48%), fruit set percentage (6.47%) and yield (11.12 kg/tree). Whereas the fruit quality parameters like TSS, acidity, reducing sugar, total sugar, ß carotene content are not significantly influenced by either due to plant spacing or flower inducer such as paclobutrazol and potassium nitrate.

“…Premature fruit drop can be caused by several factors, like for example lack of pollination or embryonic degeneration (Beyschlag et al, 1992;Lovatt, 1997;Nunez-Elisea and Davenport, 1983;Singh, 1997;Singh, 1961;Treharne et al, 1985;Yuan and Huang, 1988). Moreover, mango crop load in the previous season (Mukherjee, 1953;Pandey, 1989), pest and disease pressure (Arauz, 2000;Estrada et al, 2000;Pena et al, 1998;Verghese et al, 2005) and carbohydrate deficiency for fruit growth (Burondkar et al, 2000;Chacko et al, 1995) have also been linked to premature fruit abscission. In addition, unfavourable weather conditions combined with or intensified by genetic predisposition or insufficient fertilization may also be crucial factors in premature fruit drop in mango (Chacko et al, 1970;Lakshminarayana and Aguilar, 1975;Sukhvibul et al, 2005).…”

“…Biotic factors are mainly the lack of pollination or fertilization of flowers and pest or disease pressure that subsequently lead to seed degeneration (Singh and Arora, 1965 ). Abiotic factors associated with fruitlet drop are extensive drought periods, extreme ambient air temperatures or dry and strong winds (Burondkar et al, 2000 ; Singh et al, 2005 ; Hagemann et al, 2014 , 2015 ). In plants these factors generally reduce the auxin efflux from as well as the carbohydrate influx to the fruitlet, thus the demand of the growing fruitlet is not sufficiently matched by its supply (Wünsche and Ferguson, 2005 ; Estornell et al, 2013 ).…”

Ethephon induced abscission in mango: physiological fruitlet responses

et al. 2015

Fruitlet abscission of mango is typically very severe, causing considerable production losses worldwide. Consequently, a detailed physiological and molecular characterization of fruitlet abscission in mango is required to describe the onset and time-dependent course of this process. To identify the underlying key mechanisms of abscission, ethephon, an ethylene releasing substance, was applied at two concentrations (600 and 7200 ppm) during the midseason drop stage of mango. The abscission process is triggered by ethylene diffusing to the abscission zone where it binds to specific receptors and thereby activating several key physiological responses at the cellular level. The treatments reduced significantly the capacity of polar auxin transport through the pedicel at 1 day after treatment and thereafter when compared to untreated pedicels. The transcript levels of the ethylene receptor genes MiETR1 and MiERS1 were significantly upregulated in the pedicel and pericarp at 1, 2, and 3 days after the ethephon application with 7200 ppm, except for MiETR1 in the pedicel, when compared to untreated fruitlet. In contrast, ethephon applications with 600 ppm did not affect expression levels of MiETR1 in the pedicel and of MiERS1 in the pericarp; however, MiETR1 in the pericarp at day 2 and MiERS1 in the pedicel at days 2 and 3 were significantly upregulated over the controls. Moreover, two novel short versions of the MiERS1 were identified and detected more often in the pedicel of treated than untreated fruitlets at all sampling times. Sucrose concentration in the fruitlet pericarp was significantly reduced to the control at 2 days after both ethephon treatments. In conclusion, it is postulated that the ethephon-induced abscission process commences with a reduction of the polar auxin transport capacity in the pedicel, followed by an upregulation of ethylene receptors and finally a decrease of the sucrose concentration in the fruitlets.
