Evaluation and Screening of Single Clove Garlic Germplasm Resources and Study on Bulb Growth and Development
摘要
Abstract
In this study,we meticulously evaluated the related agronomic characters of 47 garlic germplasm resources,screening the excellent germplasm of single clove garlic,and the bulb growth and development process of typical germplasm was observed by phenotype and cytology.The results showed that among 47 garlic germplasms,the comprehensive analysis of agronomic characters of'Wenjianghongqixing'is the best,and the single clove garlic rate was much higher than other germplasm,which is the best germplasm for producing single clove garlic.The correlation analysis of main yield characters and agronomic characters showed that the single clove garlic rate was positively correlated with the transverse diameter of garlic bulb,and negatively correlated with the number of leaves per plant,plant height,pseudostem height,pseudostem diameter,leaf length and leaf width,which could be used as an auxiliary index for screening excellent germplasm of single clove garlic.By observing the growth and development phenotype of underground bulb of'Wenjianghongqixing'it was found that the growth and development of single clove garlic was divided into dormancy,germination,seedling,scale bud differentiation and bulb expansion.In the seedling stage,the diameter,girth and weight of bulb were the smallest,and the plant grew faster after entering the scale bud differentiation stage.Anatomical observation of its bulb showed that many small scale buds were formed in the bulb disc during the scale bud differentiation stage,but only one scale bud expanded to form a single clove of garlic.The results of this study will provide material and technical support for the breeding and production of single clove garlic.关键词
