摘要
以侧柏15个地理种源为试材,用光学显微镜对其鳞叶石蜡切片的解剖构造进行观察。结果显示:不同种源间叶片厚度、角质层厚度差异达到显著或极显著水平。采用叶片厚度、角质层厚度、上表皮厚度、下表皮厚度、栅栏组织与海绵组织厚度比及气孔开度6个指标,通过隶属函数法对其种源的解剖特性进行综合评价。15个种源抗旱性大小排序为:河南确山>四川射洪>山东平阴>陕西黄陵>河北获鹿>山东长清>福建南平>新疆伊犁>山东原山>辽宁凌源>山东灵岩>北京密云>山西长治>山东徂徕山>湖北荆门。
With 15 geographical provenances of Platycaldus orientalis the anatomical structure of the scale leaves was observed with the paraffin-section method under optical microscope to study the difference in drought resistance.The results showed that there were significant or extremely significant differences in the leaf thickness and cuticle thickness of the scale leaves among the provenances.A comprehensive analysis on the anatomical properties of the scale leaves among the provenances was conducted by using membership function method with 6 indices including the leaf thickness,cuticle thickness,upper and lower epidermis thickness,thickness ratio of palisade tissue to spongy tissue and the stomatal openness.The drought resistance order of these 15 geographical provenances was as Queshan of Henan Shehong of Sichuan Pingyin of Shandong Huangling of Shaanxi Huolu of Hebei Changqing of Shandong Nanping of Fujian Yili of Xinjiang Yuanshan of Shandong Lingyuan of Liaoning Lingyan of Shandong Miyun of Beijing Changzhi of Shanxi Culai Mountain of Shandong Jingmen of Hubei.
