Abstract:
... Extreme weather conditions, such as low and high air temperature changes during the growing season, play a significant role in irrigated crop yield. In this study an iterative chi-square statistical method was used to determine the relationship between air temperature and yield of dominant winter and spring irrigated crops in Shahrekord, Iran. Long term daily weather (1991–2016) and annual crop yi ...

Subject:
air temperature; coasts; cold treatment; cultivars; dormancy breaking; flowering date; heat; heat sums; olives; orchards; phenology; trees; Croatia
Abstract:
... The flowering process is adjusted to seasons through environmental signals, particularly photoperiod and temperature. Breaking dormancy, in trees, requires the completion of a period of chilling, which can be measured in hours below a certain temperature threshold. Budburst occurs once a heat requirement of accumulated degree days has been met. The studies of interactions between olive phenology a ...

Abstract:
... BACKGROUND AND AIMS: Understanding the mechanistic effects of climate change on species key life-history stages is essential for predicting ecological responses. In fire-prone regions, long-term seed banks allow post-fire recovery and persistence of plant populations. For physically dormant species, seed bank longevity depends on the maintenance of dormancy which is controlled primarily by tempera ...

Abstract:
... Overcoming dormancy represents one of the major limitations to fruit tree production in warm areas. High temperatures during the chilling period have a negative effect on breaking of dormancy. Shading of trees reduces the incidence of radiation and the temperature. Previous works on shading did not take into account the stage of dormancy. The aim of this work was to evaluate the effects of shading ...

Abstract:
... Bud-break in grapevines (Vitis vinifera L) can be poor and uneven in locations that have warm winters with insufficient chilling. Growers in these regions use hydrogen cyanamide (HC), a dormancy-breaking compound, to increase and synchronise bud-break. Previous studies demonstrated that HC upregulates the expression of select genes encoding enzymes belonging to the ascorbate glutathione cycle (AGC ...

Abstract:
... Pre-harvest sprouting (PHS) is common in cereals that lack grain dormancy if maturing grain is exposed to rain. This phenomenon leads to immediate loss of seed viability, and since the malting process requires germination, its occurrence is highly undesirable in malting barley crops. Dormancy release rate is genetically and environmentally controlled. We evaluated the effect of temperature during ...
