due to physiological disorder, primary bud necrosis (pbn) in grapevine is a great problem in vineyards, resulting in reduced yield. primary bud necrosis (pbn) is physiological disorder resulting in the death of the primary bud. the present study conducted through a light on this critical problem in a vineyard of cisakht region. a factorial experiment with three levels of cold temperature (-10, ...

BACKGROUND AND AIMS Spring geophytes require a period of low temperature for proper flower development but the mechanism that underlies the relationship between cold treatment and flowering remains unknown. The present study aims to compare the developmental anatomy and carbohydrate content of the tuberous geophyte Corydalis bracteata growing under natural winter conditions from 10 to -10 degre...

Bud necrosis (BN) of grape is observed as an abortion and drying of one or more primordia of the developing compound winter bud. The causes are uncertain, but high vigor, and canopy shade increase BN incidence under some conditions. This work was conducted to determine if localized carbohydrate or mineral nutrient deprivation increased the incidence of BN observed with ‘Riesling’ grapes in Virg...

Radish floral bud abortion (FBA) is an adverse biological phenomenon that occurs during reproduction. Although FBA occurs frequently, its mechanism remains unknown. To elucidate the molecular mechanism underlying FBA, we detected gene expression differences between aborted and normal buds of radish using cDNA-amplified fragment length polymorphism (AFLP) and real-time polymerase chain reaction ...

primary bud necrosis is a physiological disorder that adversely affects the performance and yield in the vineyards. the present study was conducted to determine the time and intensity of bud necrosis incidence as well as the related anatomical changes in the developing buds of grapevine cv. askari. a factorial experiment in a randomized complete block design of 4 replications was carried out fo...

in this study, the effects of different types of hand plucking were studied on green leaf yield and black tea quality. bud and a leaf, bud and two leaves, bud and three leaves and bud and four leaves were the types of hand plucking. plucking was down on chine’s hybrid tea and clone 100 in fuman tea research station. shoots were plucked in flashing period regularly during three years. green leaf...

abstract persian walnut is one of the most important nut crops in iran. now the majority of orchards are seedling with a great diversity. for establishing uniform orchards and increasing the quantity and quality of yield, patch budding as the most suitable propagation methods, have still technical and practical problems in the country. in spite of high percent of primary success in patch buddin...
