Abstract
Under rain-prevention shed pond culture and pot culture,It was investigated in this paper the effect of drought at different growth stages on senescent characteristics and yield of peanut by artificially controlling irrigation.The results showed: at different growth stages when peanuts plant was subjected to water stress,chlorophyll content,photosynthetic rate,SOD,POD,CAT activity of peanut functional leaves and root activity all decreased.MDA content increased.Pegging stage and pod bearing stage had the most important effect of drought on senescent physiology.All drought treatment led to pod yield and productivity per plant decrease,among which,the drought treatments at pegging stage and pod bearing stage had the greatest effect on yield formation.
