Pollen germination of Vitis vinifera L., of the family Vitaceae was examined in fresh and stored pollen upto 48 weeks at different temperature i.e., refrigerator (+4C), freezer (-20C, -30C) and freeze drier (-60C). Pollen stored at low temperature showed better germination percentage as compared to pollen stored at +4C and fresh. Freeze dried pollen (-60C) showed the highest germination percent...

Changes in the global water cycle can cause major environmental and socioeconomic impacts. As the average global temperature increases, it is generally expected that the air will become drier and that evaporation from terrestrial water bodies will increase. Paradoxically, terrestrial observations over the past 50 years show the reverse. Here, we show that the decrease in evaporation is consiste...

Yield variability in cotton (Gossypium hirsutum L.) from year to year in different environments (geographical locations) is a major production problem for farmers (Oosterhuis, 00 ). Higher yields have been recorded in the drier environment of California, compared to the more humid environment of Arkansas. However, the effect of environmental factors, such as temperature, relative humidity, and ...
