frost occurrence during plant growth created special conditions to evaluate the effects of planting date on dry matter content and agronomical characteristics of potato cultivars influenced by natural frost in field conditions. a split-plot experiment with three replications was carried out to compare three planting dates, as main plot, from 1 to 21 november with 10 day intervals and four culti...

Radiant spring frosts occurring during reproductive developmental stages can result in catastrophic yield loss for wheat producers. To better understand the spatial and temporal variability of frost, the occurrence and impact of frost events on rain-fed wheat production was estimated across the Australian wheatbelt for 1957-2013 using a 0.05 ° gridded weather data set. Simulated yield outcomes ...

introduction frost is one of the most hazardous natural phenomena which it is at times accompanied by abundant damages in the life and properties. freezing and frost are very important for agricultural products in different stages of the growth. this is because, in case of happening, it results in the reduction of the products. frost is the stage of water freezing. in such condition, when the a...

The purpose of this study was to test the hypothesis that a reduction in resting rectal temperature (Tre) is partially responsible for the attenuation in the rise of core temperature during heat exposure following acclimation to humid heat. Nine male volunteers completed 7 days of acclimation, performing 2 h of exercise per day in a hot, humid environment (35°C, 75% relative humidity). Mean (±S...

Seedlings of Leptospermum scoparium J.R. et G. Forst (manuka) originating from seed from a low altitude coastal site (Auckland) and from a high altitude inland site (Desert Road) were grown for 96 days in four controlled environments to compare the relationship between growth temperature and frost hardening. Day/night temperature treatments were 12/6, 12/3, 12/0 and 12/-3 degrees C. Frost hardi...
