Abstract
A three replicate, split plot design was used with species as main plot treatments and shading as subplot treatments. Species treatments included Indica hybrid Ⅱ you 162, Dyou 68 and Gangyou 22. Shading treatments began after 10% panicles heading, and subplot treatments were wrapped with one or two layers of 49% shade or 69% shade. The leaves characteristics were measured. The leaves characteristics were obviously affected by the low light stress. The length and the width of leaves under low light stress were greater than those of the control. The average LAI of each species in 49% shade was higher than that of the control, and the LAI of each species in 69% shade was lower than that in 49% shade. The SLA of Dyou 68 and Gangyou 22 increased while the light density decreased. The chla, chlb, chl (a+b) increased, and chl a/b decreased while light density decreased. The relative dry matter weight of leaves in 49% shade or 69% shade was higher than that of the control.
