“…These results mirror the findings of Pandey et al, (2017), who discovered that paclobutrazol had a substantial impact on the length and diameter of the fruit of cashew nuts and that the chemical had a greater effect with higher doses. Lurie et al, (1997) also reported that paclobutrazol application decreased vegetative growth and enhanced fruit growth development during the year following application.…”

This study focuses on the residual effect of paclobutrazol on the vegetative growth, flowering, yield, and quality of litchi grown at the Horticulture Research Centre, Patharchatta, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar during the period 2016– 2019. A total of 45 litchi trees were included in this experiment. The treatments consisted of four doses of paclobutrazol at 1.0 g a.i. (20 ml/tree), 2.0 g a.i. (40 ml/tree), 3.0 g a.i. (60 ml/tree), and 4.0 g a.i (80 ml/tree) per meter canopy diameter. The doses were applied on three dates, September 15, October 15, and November 15, through soil drenching in the years 2016 and 2017, subsequently. Plain irrigation water was applied in the basins of trees which served as control. The results show that application of paclobutrazol at 3.0 g and 4.0 g a.i. Per meter canopy diameter during 2016 and 2017 were the most effective in suppressing vegetative growth as compared to control. Higher doses of paclobutrazol persisted in the soil for longer duration and consequently affected flowering and fruiting during 2019. The trees treated with higher doses of paclobutrazol displayed more residual effects on flowering, fruiting, yield, and quality parameters during 2019.

“…It also causes greater partitioning of assimilate to reproductive growth, flower bud formation, and fruit growth (Lever 1986;Quinlan & Richardson 1986). Paclobutrazol has been used in several Prunus species for improving productivity and fruit quality (Knowles & Dossier 1986;Blanco 1987;Facteau & Chestnut 1991;George & Nissen 1992;Lurie et al 1997;Grochowska et al 2004). However, studies of paclobutrazol application in apricot are limited and not conclusive about reproductive behaviour and increase in yield (Proebsting & Mills 1985;Jacyna & Dodds 1995).…”

Shading all or parts of trees and the application of paclobutrazol during the dormant season, were studied as strategies to improve apricot (Prunus armeniaca) fruitfulness. Shading the whole tree reduced flower bud abscission, probably because of a decreased level of gibberellins resulting from a reduction of temperature in the shaded trees. Partial shading of individual branches did not reduce percentage of flower bud abscission compared to unshaded branches. Shading also accelerated ovule maturity at anthesis. These results show the importance of solar radiation on the basic structure of the tree (the trunk and primary branches) for the productive behaviour of apricot. Paclobutrazol treatments did not significantly influence flower bud drop and fruit set on apricot during the 2 years of the study. However, these treatments slightly accelerated ovule maturity at anthesis, probably because of the reduction in the level of gibberellins.

“…Internal flesh browning appears due to enzymatic oxidation of polyphenols and gel breakdown in flesh caused by the presence of large water-soluble pectins that bind water into gel (TAYLOR et al 1993;LURIE et al 1997). Optimal storage atmosphere is based on physiological tolerance to O 2 and CO 2 (according to BEAUDRY 1993BEAUDRY , 1999 as undesirable responses to the induction of fermentation.…”

Plum fruits of the cultivars Stanley and Valjevka picked at the beginning of climacteric were stored in different storage atmospheres for 31 days at 3°C. The relations between the O 2 and CO 2 content during this period and after removal from the gas mixture to ethanol, acetaldehyde, non-volatile compounds and some textural values of fruits were investigated. Concentrations of ethanol in the flesh were related to levels of oxygen and CO 2 in ambient atmosphere. In anaerobic conditions (< 0.2% O 2 ) ethanol reached 1,109 mg/l for the cultivar Valjevka and 628 mg/l for Stanley. The results of single fruit analysis showed a steeply increasing concave curve of ethanol production in the period of anaerobic conditions, followed by the phase of a drop of the production rate in air stored fruit. The concentration of oxygen at a level of 0.9% (ultra low oxygen -ULO) does not physiologically harm the tissues of plums by producing mostly negligible content of ethanol and acetaldehyde, but an ethanol increase to half concentration after 31 days was observed to compare with anaerobic conditions in the cultivar Valjevka. From this aspect plums seem to be relatively sensitive to low oxygen. The post-storage period was extended up to 53 to 63 days, respectively. The senescence caused an increase in ethanol production rate that was exponentially increased after 20 days of cold storage atmosphere. The final concentration after 53 days was still higher for cv. Valjevka than for cv. Stanley at the respective content of 828 mg/l and 498 mg/l. Skin firmness was differentiated for both cultivars, and softness was higher for the cultivar Valjevka.
