大棚秋冬茬紫芽青萝卜农艺性状、光合参数及可溶性糖比较分析
Comparative Analysis of Agronomic Characters,Photosynthetic Parameters and Soluble Sugar of'Ziyaqing'Radish in Greenhouse in Autumn and Winter
摘要
Abstract
In order to evaluate the growth status of 8 lines of'Huaikeqing'radish(No.1-No.8)under greenhouse cultivation,the main agronomic traits,photosynthetic parameters and soluble sugar content of each lines of'Ziyaqing'radish were determined,and the difference significance analysis and correlation analysis of each index were carried out,in order to screen out the varieties of'Ziyaqing'with better comprehensive characteristics,The results showed that the fleshy root weight of the tested'Ziyaqing'ranged from 167.63 to 286.65 g,of which'No.3'was the most significant.The ratio of root weight to leaf weight of'No.3'was 5.01,which was significantly higher than that of other lines.Among photosynthetic parameters,net photosynthetic rate of'No.1',transpiration rate of'No.3'and stomatal conductance of'No.8'were the highest.The soluble sugar content of'No.3'and'No.6'was 225.44 mg/g and 227.19 mg/g,respectively.Correlation analysis showed that net photosynthetic rate,transpiration rate,stomatal conductance and soluble sugar content were closely related with root weight index of meat quality.In conclusion,'No.1''No.3'and'No.8'can be used as high-yield germplasm resources,and'No.3'and'No.6'can be used as high-quality germplasm resources.关键词
