18个枣品系花器官形态特征分析
Analysis of Floral Organ Morphological Characteristics in 18 Jujube Strains
摘要
Abstract
It aims to study and analyze the morphological characteristics of flower organs of different jujube strains,so as to provide a theoretical reference for the selection of excellent varieties.Taking 18 jujube seedlings from the seedling selection nursery at Tarim University as the research material,we observed the phenotypic traits of the floral organs,measuring the flower diameter,nectary disc diameter,and stamen length.We also determined the pollen viability and pollen quantity per anther.The jujube floral structures were evaluated using correlation analysis and the subordinate function comprehensive evaluation methodology.The results showed that:Flower morphology was closely correlated with pollen fertility.Superior lines performed well both morphologically and in terms of fertility.MX5B11 exhibited significant advantages in larger flower diameter,larger nectary disc diameter,and longer stamens,while DNJ5B1 and DNJD4B9 showed prominent performance in pollen quantity and pollen viability.These findings provide important references for future breeding programs.关键词
