Six leaf traits,i.e.,fresh mass (FM),dry mass (DM),leaf dry matter content (DMC),area (AR),specific leaf area (SLA) and thickness (TH) from 23 plant species in the southeaste Keerqin Sandy Lands,China were measured.The results show that leaf traits of herbs were more diversified than those of shrubs and trees and aver-age SLA tended towards a decreasing trend from herbs to shrubs to trees.On the contrary,DMC and DM show an upward trend from herbs to shrubs to trees.No apparent difference was found in TH.Except for DM and TH,there were significant variations in SLA and DMC among three different growth forms.Moreover,a significant correla-tion was found between SLA and DMC.It is concluded that SLA and DMC could be used to predict species posi-tion along a resource use gradient.

水稻是重要的粮食作物之一。由立枯丝核菌(Rhizoctonia solani Kuhn)引起的纹枯病在我国南方部分稻区已成为水稻第一大病害,造成巨大的产量损失,培育抗病新品种迫在眉睫。抗纹枯病水稻新种质YSBR1来源于籼、粳交后代群体,多年田间接种鉴定试验中均表现出对纹枯病较高水平的抗性。本研究以抗病种质YSBR1为父本、感病品种Lemont为母本,构建F2无性系群体定位抗纹枯病QTL；通过回交及
