Abstract:

AbstractThe endogenous ABA contents of dormant and nondormant barley grains were determined following application of different compounds to break dormancy. The chemicals used for breaking of dormancy in intact dormant grains were weak and strong acids, alcohols, hydrogen peroxide, cyanide, nitrate, salicylic acid, gibberellic acid and fusicoccin. The dormancy-breaking compounds could be classified into two major groups: compounds that caused a decrease in endogenous ABA (class I) and compounds which did not affect endogenous ABA (class II). Class I compounds included gibberellic acid, ethanol,

Abstract:

AbstractMany research questions focused upon seed dormancy and germination remain unanswered due to problems created by inappropriate assumptions concerning the design and implementation of experiments. Lack of attention to the genetic background and growing conditions required for seed production and subsequent storage may compromise an investigator's ability to pool data or assimilate data trends due to variability in seed performance from year to year. Seed aging events during the afterripening process can be mistaken for those involved in the transition from the dormant to nondormant state

Abstract:

At the beginning and near to the end of the endodormant period, cytokinin-type growth regulators are effective to end dormancy in apple. The same growth regulators are not effective during the middle of this period. Terminal buds require less chilling than lateral buds to emerge from the dormant period. Lateral buds on decapitated shoots also require less chilling, indicating that auxin may be involved in dormancy. Replacing the terminal with IAA keeps water in bound state in the lateral buds, indicating the effect of IAA in dormancy. We have developed the theory that the beginning and the end

Abstract:

The aim of this study was to examine the dormancy behavior of Euphorbia dracunculoides and Astragalus spp., weeds of arid chickpea.

Adequate chill is of great importance for successful production of deciduous fruit trees.

Three chemicals, Alzodef (49% hydrogen cyanamide) at 20 mL/L, thiourea at 10 g/L and potassium nitrate at 40 g/L were tested either alone or in combination for their effects on breaking dormancy in the low chill nectarine cultivar Sunred in subtropical Queensland. Compared with potassium nitrate and thiourea, Alzodef proved more effective in breaking dormancy and advancing budbreak and fruit maturity. However, Alzodef reduced both fruit set and final yield. Yield losses were greater when application of Alzodef was delayed from 5 weeks to 1 week before natural budbreak.

Abstract:

A method to quantify the chilling status of grapevines grown in a desert region, in order to better predict vine response to dormancy-breaking chemicals, was examined. Chilling status was determined by calculating the ratio between exposure to chilling temperatures (hours ≤7C) and chill-negating temperatures (hours ≥20C) from the beginning of the dormant period (1 Nov.) to the date of pruning (mid-December). A 6-year field study (1991 to 1996) compared the budbreak of untreated vines, and vines treated with H2CN2 (2% v/v) immediately after pruning, exposed to a range of chill:chill negation ra

The way these are computed in the face of global warming is explained, using the dynamic model.

Abstract:

Temperate zone fruit crops undergo bud dormancy which can be described as a mechanism for avoiding the exposure of tender flowers and leaves to low winter temperatures. In Kenya, apple growing is mostly hampered by inadequate chilling that causes the plants to have prolonged dormancy leading to poor flowering and consequently low yield. Although the chilling requirements are obligatory, under subtropical and especially tropical conditions avoidance is possible. To achieve this, it is necessary to select cultivars with low chilling requirements. This has proven effective in Zimbabwe with cultiv

Abstract:

Chemical dormancy breakers are often used to manipulate floral bud break in sweet cherry production, and their use is increasing due to unpredictable climate effects. The role of plant hormones in regulating the critical transition of floral buds from dormant to opening in deciduous trees is now emerging. By monitoring changes in endogenous hormone levels within floral buds that are undergoing the transition from dormant to the growing state in response to various cues (environmental and/or chemical inducers), we can begin to distinguish the plant hormones that are the drivers of this process.

Abstract:

In the modern floricultural industry, scheduling plant production is essential due to fluctuating market demands. Flower forcing, which stimulates flowering at specific dates or during off-season periods, is a key technique employed. The manipulated flowering dates resulting from flower forcing may deviate from the plant's natural schedule, occurring either earlier or later than the standard flowering dates. This can be achieved by adjusting factors affecting flowering such as temperature, photoperiod, and irradiance etc. Implementation of special practices like pruning, leaf trimming, dormanc

Abstract:

Under inadequate chilling conditions, hydrogen cyanamide (HC) is often used to promote budbreak and improve earliness of Southern highbush blueberry (Vaccinium corymbosum L. interspecific hybrids). However, HC is strictly regulated or even banned in some countries because of its high hazardous properties. Development of safer and effective alternatives to HC is critical to sustainable subtropical blueberry production. In this study, we examined the efficacy of HC and defoliants as bud dormancy-breaking agents for ‘Emerald’ blueberry. First, we compared water control, 1.0% HC (9.35 L ha–1), and

Abstract:

The purpose of this research was to determine the effectiveness of alternatives of dormex on apricot budbreak and their effect on apricot fruit quality. Our study was carried out on five-years old “Canino” apricot at Badr district, El Behira Governorate, Egypt, during the two seasons 2022 and 2023, respectively. Twenty-four uniform apricot trees were selected and sprayed to the runoff once on 20 and 25 January during 2022 and 2023, respectively, by following treatments: control, mineral oil at 2%, low pyrite urea at 2%, ammonium nitrate at 1.5%, potassium nitrate at 2%, mineral oil combined wi

Abstract:

Abstract Germination rate and percent germination are low for most cycads, including Encephalartos altensteinii, thereby affecting the production and conservation efforts for this endangered plant group. Although seed germination experiments for cycads have been done mainly on Zamia and Cycas, there is limited germination research on the African genus Encephalartos. The effects of hydration-dehydration treatment on seed longevity, embryo development, moisture content and viability were studied by hydrating seeds of E. altensteinii Lehm during storage for 24 hr and dehydrating for 96 hr every m

Abstract:

Yams are important items of diet throughout the Caribbean Region and, among them, the cultivars of the species, Dioscorea alata L. and D. esculenta (Lour.) Burkill are particularly important in the Eastern and Southern Caribbean, although the latter is so to a lesser extent. With a growing period of approximately nine months and a corresponding dormancy period, these cultivars are produced on an annual basis like clockwork, providing food yams for approximately three months of the year, the period of availability coinciding with the period of dormancy as the latter marks the natural period of
