Abstract:
‘Shouxin 98’ was chosen as the plant material and EM50 was applied to control water content.The effects of water stress on leaf senescence and root activity in fruiting period of greenhouse tomato were studied.Four models of water supply were conducted，which included normal water supply (CK，field water holding capacity of 70%-80%)，light stress (field water holding capacity of 60%-70%)，moderate stress (field water holding capacity of 50%-60%) and severe stress (field water holding capacity of 40%-50%).The results showed that photosynthetic pigment increased first and then decreased with the reduction of soil moisture.The photosynthetic pigment with the light stress was significantly higher than other treatments.The activity of superoxide dismutase (SOD)was the same as peroxidase (POD)，showed a trend of increasing first and then decreasing among different water treatments.SOD and POD activity of tomato plants decreased with the reduction of soil moisture,showed severe stress treatment>moderate>light>CK.SOD and POD activity were the highest in fruit enlargement stage.The light stress，moderate stress，severe stress of SOD activity were 1.00，1.82，1.68 times than CK in fruit enlargement stage respectively，and those of POD activity were 1.81，2.37，2.91 times than CK.The root activity of tomato could be increased significantly under light stress，but it decreased to different degree under other water treatments.The light stress，moderate stress，severe stress of root activity were 102.08%，90.62% and 80.56% of CK in mature stage respectively.Therefore，light water treatment could promote the synthesis of photosynthetic pigment，increase the root activity and slow down the aging pace by improving greenhouse tomato tolerance to water stress.
