Evaluating the interactive effect of nutrient addition and prior heat stress on shoot height, leaf area and number of leaves of V. unguiculata during growing period, our result revealed that there was a progressive increase in the number of leaves, leaf area and shoot height from the first week of the nutrient treatment to week 8 (Figures 1, 2 and 3)
Summary
The frequency of extreme stress event on plant growth, development and yield differ among varieties of plant species, depending on the prevailing optimal environments as well as the susceptibility capacity of individualAfr. The frequency of extreme stress event on plant growth, development and yield differ among varieties of plant species, depending on the prevailing optimal environments as well as the susceptibility capacity of individual. Heat as a complex function of intensity, duration and rate of increase in temperature can cause declines in photosynthetic efficiency, leaf senescence, shoot and root growth inhibition, impairment of pollen and anther development, and subsequently reduction in yields (Karim et al, 1999; Sato et al, 2006; Wahid, 2007; Zhang et al, 2005). Heat stress due to high temperatures is a crucial threat to crop production worldwide (Hall, 2001) as it causes reduction in yield and dry matter production in many crops (Giaveno and Ferrero, 2003)
