摘  要：
试验于2016-2017年在江苏南京江苏省农业科学院经济作物研究所试验田进行,引进不同地区的20个地方大蒜品种,研究大蒜苗期农艺性状与青蒜产量的关系,明确影响青蒜产量的主要农艺性状。结果表明,大蒜苗期主要农艺性状变异系数达7.02%～36. 81%,以植株鲜质量变异幅度最大,假茎高次之,且各性状的变异幅度因播期而异。植株鲜质量与株高、假茎高、假茎粗和叶宽极显著正相关,与叶长显著正相关,与株高/假茎高极显著负相关。多元回归和通径分析明确大蒜苗期假茎粗、假茎高和叶宽是影响蒜苗产量的主要农艺性状,可作为青蒜品种引进和选育的主要评价指标。

摘  要：
The experinent was conducted in the experimental field of Institute of Industrial Crops,Jiangsu Academy of Agricultural Sciences from 2016 to 2017. In the present experiment,the twenty garlic cultivars were selected to study the relationship between yield of garlic sprout and agronomic traits during garlic seedling stage,including plant height( PH),stem height( SH),stem diameter( SD),leaf length( LL),leaf width( LD),plant fresh weight( PFW) and PH/SH. The results showed that the variation coefficient of main agronomic traits during garlic seedling stage ranged from 7. 02% to 36. 81%. Among the agronomic traits,the PFW had the most variation,followed by SH. The plant fresh weight was very significantly positively correlated with PH,SH,SD and LD,positively correlated with LL and had a significant negative correlation with PH/SH. Multiple regression and path analysis results showed that SD,SH,LD were the main factors affecting garlic sprout yield in seedling stage,and could be used as main evaluation indices for the introduction and breeding of garlic sprout.
