Pollen Development and Chilling Requirements in Apricot Cultivars
Apricot (Prunus armeniaca L.) flowers at the end of the winter but flower bud differentiation occurs the previous summer. During the winter, the flower bud enters dormancy and resumes growth prior to flowering. The time the flower bud remains dormant is genetically and also environmentally controlled and is a major factor determining the adaptation of particular cultivars to particular ecologic...
متن کاملImbibitional Chilling Injury in Pollen
Chilling injury is sustained by dry pollen of Typha latifolia L. upon hydration in germination medium at 0°C. This injury is evidenced as poor germination, low vigor, and depressed respiration. Isolated mitochondria showed multiple sites of impaired electron transport. Besides losses of cytochrome (Cyt) c and NAD+, the activities of membrane-bound enzyme complexes such as Cyt oxidase, NADH-duro...
متن کاملChilling requirement of Ribes cultivars
It is usually thought that adequate winter chill is required for the full flowering of many temperate woody species. This paper investigates the sensitivity of blackcurrant bud burst and flowering to natural weather fluctuations in a temperate maritime climate, and compares a range of chill models that have been proposed for assessing the accumulation of winter chill. Bud break for four contras...
متن کاملComparison of Utah and Positive Utah models for determining of chilling and heat requirements of some olive cultivars
Determining of chilling and heat requirements of olive cultivars growing in Fars Province is important for the selection of cultivars that will exhibit satisfactory growth and development. The purposes of this study were determining the chilling and heat requirements of olive and comparison of Utah and Positive Utah Chill unit (PCU) models for determining the chilling requireme...
متن کاملevaluation of temperature requirements of six apricot cultivars under lab and field conditions in shahrood
in this research, chilling and heating requirements of six local cultivars of apricot (jafari, ghavami, jahangiri, khiari, khiveaee and rajabali) were evaluated under field and lab conditions. under lab condition, ‘rajabali’ and in some extent ‘johangiri’ began flowering after 500 hours in 4°c. other cultivars except ‘khiari’ flowered at 750 h. ‘khiari’ flowered at 1000 h. in field, due to litt...
