Effect of Growth Regulators and Fungicides on Fruit Drop, Yield and Quality of Fruit in Ber CV. Umran
Journal of research, 2001Co-Authors: Kanwarjit Singh, J. RandhawaAbstract:Studies were conducted at Punjab Agricultural University, Ludhiana to see the effect of chemicals on Fruit Drop, yield and quality of Umran ber. NAA, 2, 4-D, GA3, each at 15, 30 and 60 ppm concentrations, fungicide treatments of Blitox (2000, 3000 and 4000 ppm) and Bavistin [carbendazim] (500, 1000 and 1500 ppm) were sprayed orrthe tree. It was found that NAA treatments were best in improving yield and quality of Umran Fruits. Highest yield, largest Fruit size and total soluble solids each was recorded with NAA (60 ppm), whereas 30ppm NAA treatment resulted in lowest acidity and highest ascorbic acid content. GA3 treatments considerably reduced the Fruit Drop, increased Fruit set and also improved yield of ber Fruits. GA3 at 60ppm recorded the lowest Fruit Drop, highest Fruit set and yield. Fungicide treatments of Blitox and Bavistin had little or no effect on Fruit Drop and yield, however, 1500 ppm, Bavistin treatment recorded highest Fruit weight of ber cv. Umran.

Moderate plant water stress reduces Fruit Drop of “Rojo Brillante” persimmon (Diospyros kaki) in a Mediterranean climate
Agricultural Water Management, 2013Co-Authors: E. Badal, T.a. Abd El-mageed, I. Buesa, D. Guerra, Luis Bonet, Diego S. IntriglioloAbstract:Abstract Spring Fruit Drop is a crucial determinant for yield in persimmon trees. Several environmental and tree endogenous factors can determine the magnitude of this physiological phenomenon. In this sense, plant water status might play a pivotal role in persimmon Fruit Drop occurring during spring. The main purpose of this study was to establish and quantify the effects of plant water stress on Fruit Drop of the ‘Rojo Brillante’ persimmon cultivar. To achieve this goal, a field experiment was conducted during three consecutive seasons with mature trees. Three irrigation regimes were tested: Control, always well watered; and two deficit irrigation (DI) treatments where water was applied at 50% of the Control regime during May and June (DI early ) or during July and August (DI late ). Plant water stress was monitored by means of midday stem water potential ( Ψ stem ) readings. The seasonal variation of Fruit Drop was quantified during the entire Fruit abscission period. Both DI regimes led to lower Fruit Drop than the Control (31 and 12% lower Fruit Drop for DI early and DI late , respectively). In addition, in the last two experimental seasons, there was a highly significant relationship between the amount of Fruit that Dropped during the physiological Fruit Drop and the average Ψ stem for the period of water restrictions. However, the timing of water stress also affected the existing relationships. Early season water stress had a greater effect on reducing Fruit abscission during the second wave of Fruit Drop. In semi-arid climates, this knowledge can be used for increasing ‘Rojo Brillante’ persimmon Fruit set by restricting irrigation applications during late spring.

Blueberry Fruit Drop-associated virus: A New Member of the Family Caulimoviridae Isolated From Blueberry Exhibiting Fruit-Drop Symptoms.
Plant disease, 2016Co-Authors: Alfredo Diaz-lara, Robert R. MartinAbstract:This study describes the nucleotide sequence and genome organization of a new DNA virus isolated from 'Bluecrop' blueberry plants exhibiting Fruit-Drop symptoms and named Blueberry Fruit Drop-associated virus (BFDaV). Blueberry Fruit Drop disease was first detected in blueberry plants in British Columbia, Canada in the late 1990s, and in a single field in northern Washington state in the United States in 2012. Infected bushes abort nearly 100% of their Fruit about three weeks prior to harvest, when the berries are about 3 to 5 mm in diameter. At harvest, the affected plants appear taller than healthy ones as there is no Fruit weighing down the branches. The virus was amplified from diseased material using rolling circle amplification, followed by enzyme digestion, cloning, and sequencing. The full genome of BFDaV is 9,850 bp in length and contains a single open reading frame, encoding for a polyprotein, and a large noncoding region. Based on the genome size and organization and phylogenetics, BFDaV is proposed as a new and the largest member of family Caulimoviridae. Finally, in mapping part of a field with Fruit-Drop symptoms, there was a nearly perfect correlation between the presence of the virus and Fruit-Drop symptoms.
