杧果种质部分生物学性状指标评价分析

摘要 对杧果树10个主要生物学性状指标主枝与主干夹角、叶片长度、叶片宽度、花序长、花序宽、两性花直径、雄花直径、果实长度、果实宽度、单果重进行了分析，发现其具有丰富的多样性，对包括叶形指数、果形指数在内的12个性状指标进行了分级或分类，提出了现阶段适用性更强的生物学评价参考标准，列出了具体的数据指标，提出了参照品种，为芒果种质资源的系统评价打下了一定基础。

Evaluation and Analysis of Some Biological Characteristics on Mango(Mangifera Indica) Genetic Resources

10 index for major biological traits of 73～167 accessions of mango i.e.tree bough and trunk angle,leaf length and width,inflorescence length and width,bisexual flower and male flower diameter,fruit length and width,single fruit weight were used to evaluate mango in the germplasm repository of mango of the Ministry of Agriculture in Danzhou City,Among 10 index,abundant biologic diversity was found and classification were carried out using 1-5 grade classification method by 11 index including the leaf index.An applicable reference standard was assumed using specific data indicator and reference cultivars,which lay a certain foundation for the system evaluation of mango germplasm resources.
