【摘要】 贵州西部是我国特有物种矮杨梅植物的主要分布地。贵州矮杨梅植物资源十分丰富,它不仅在食品、轻工、医疗等方面有综合开发利用的价值,而且在植物个体间有形态上明显的差异,在同一野生状态下产生了果形、果色、叶形、植株性状等分化稳定的多种类型,可视为矮杨梅植物资源多样性的基因库。本文介绍了贵州矮杨梅植物的分布、自然概况、主要变异类型和种质资源保存试验,并对矮杨梅物种的研究意义进行了讨论。
【Abstract】 Myrica nana Cheval,a species endemic to China,is mainly distributed in the west of Guizhou Province.This species was found to have distinct differentiation in some morphological characters,such as the shape and the colour of the fruits,the shape of the leaves,etc.In this paper, its geographical distribution,habitats and major variation patterns as well as the results of some germplasm conservation experiments,are reported.In addition,the importance of further studies on this species is also discussed.
