绿玉树(Euphorbia tirucalli L.)系被子植物门双子叶植物纲金虎尾目大戟科大戟属(光棍树属)植物,起源于东非热带国家。绿玉树在医药、园林等方面具有广泛的用途,其乳汁富含萜类、甾醇类及碳氢化合物,是重要的能源植物。但绿玉树关于栽培、生理及遗传等方面的研究非常少,国内外只有少数几篇文章报道。本研究对采集于不同地点的46份绿玉树种质资源进行形态和分子标记鉴定,合并相同种质,在此基础上对于鉴定出属于不同种质的材料,利用ISSR和SRAP两种标记对其进行遗传多样性分析,并对其进行株型、生长速

In this paper, we present a general approach to the construction of conservation laws for generalized classical dynamical systems. Firstly, we give the definiti
We propose a set of single mode rate equations for multi-section distributed feedback (DFB) lasers. On the basis of the rate equations, the self-pulsation in th
