The present paper is focused on an assessment of the effects of stand density and leaf area development on radiation use efficiency in the mountain cultivated Norway spruce stand. The young even-aged ...
Effects of Temperature,Solar Radiation,and Vapor-Pressure Deficit on Flower Opening Time in Rice
Flower opening in the early morning Flower opening time Heat-induced sterility Oryza sativa Rice cultivars Solar radiation Temperature before anthesis Vapor-pressure deficit
2010/3/4
Flower opening in the early morning helps to avoid sterility of rice (Oryza sativa L.) caused by heat stress at anthesis. Although flower opening time (FOT) is under genetic control, it is also affect...
Effects of the Diurnal Change of Solar Radiation and the Temperature on the Change of Ascorbic Acid Content of Spinach
