| 摘 要： | 本文以马尾松的四个家系（广西家系：38#、464#、127#、83#）和一个地理种源（台江#）共五个处理为材料．观察其针叶的解剖构造，主要包括表皮厚度、下皮厚度、绿色折叠组织厚度、角质层厚度及气孔开度，研究马尾松抗旱适应性。结果表明：不同处理的马尾松针叶解剖构造具有一定差异，其中绿色折叠组织、角质屡厚度、气孔开度差异达显著水平，通过隶属函数计算综合评价，38#家系、464#抗旱能力最强，其次为台江#与127#．83#家系抗旱能力最弱。

| Abstract: | Four genealogies (Guangxi: 38 #, 464 #, 127 #, 83 #) and one provenances (Guizhou: Taijiang#) of Pinus massoniana L. were studied in the anatomic structures of the needles, including epidermis thickness, hypodermis thickness, mesophyll thickness, cuticle thickness and stomatal aperture. The result showed that the mesophyll thickness, cuticle thickness and stomatal aperture were significantly different among different samples. By the analysis through the membership function calculation, it was concluded that 38# and 464# had the highest capability of drought-resistance, followed by Taijiang# and 127#, and 83# the lowest. |
