Abstract

Four water treatment was set to pot planted Luomai 9133 to study the leaf physiological characteristics of its seedlings under water stress.Leaf water potential,leaf relative water content,chlorophyll a content,chlorophyll b content,and total chlorophyll content were decreased with soil water reduction while leaf water sufficiency and deficiency,(soluble) sugar content,proline content,the permeability of plasma membrane,MDA content,and SOD activity,POD activity were increased.These showed that Luomai 9133 seedling leaf increased drought-resistance by changing inner physiological characteristics.
