树莓、黑莓不同品种叶解剖构造与抗旱性的研究

Anatomical Structures of Leaves of 13 Rasberry and Blackberry Varieties and Their Drought Resistance Features

选取7项叶片旱生结构指标(叶片厚度,栅栏组织厚度/叶肉组织厚度,细胞密集度,角质层厚度,上、下表皮厚度),观察测定了13个树莓和黑莓品种的叶片的相关指标。方差分析结果显示,13个树莓和黑莓品种在每个抗旱性指标上均差均极显著.对各品种进行了两两之间的单因素多重比较,以3个指标为主进行综合分析对各品种抗旱能力进行排序:威廉姆特>英国红>彻斯特>塞尔文>百胜>图拉明>美国红>费尔多德>佳果>黑巴提>奥瑞斯>俄国红>秀美特。

Drought resistances of leaves of 13 rasberry and blackberry were measured based on 7 xeromorphic indexes ,including thickness of leaves, ratio of palisade tissue thickness to cutis tissue,thickness extent of palisade cell density,thickness of cuticular,thickness of two sides of cutis . The variance analysis showed that differences of each drought resistance index among the 13 varieties were extremely significant, then the single factor multiple comparisons between two varieties were calculated. According to the 3 indexs , an order of dought resistance of the 13 varieties was given from hight to low by synthetical method i.e. ： Willamette,rasberry from England,Chest,Silvan ,Boysen ,Tulameen ,rasberry from American,Sertodi, Kiowa, BlackButte ,Orus, rasberry from Russian,Summit
