Abstract:
The pot culture experiment was conducted at Agro Climate Research Centre of Tamil Nadu Agricultural University, Coimbatore during 2017. Attempts have been made in Trianthema portulacastrum to reveal the survival and seed production capacity with different temperature and moisture level of 100, 80, 60 and 40% under climate control chamber. The results explained that the vegetative growth was higher in ambient temperature with 100% moisture level and it was comparable with elevated temperature of 4⁰C from the ambient temperature with 100 and 80% moisture level. Reproductive phase was detrimentally affected by the higher temperature and moisture stress. Elevated temperature of 2⁰C from the ambient temperature has higher number of seeds under optimum moisture levels than ambient temperature. Hence in near future increase in temperature enhance the growth of weeds which will directly affect the crop growth and productivity by inducing competition effect for moisture and nutrients.
