Analysis and Comprehensive Evaluation of the Growth and Quality Characteristics of Non-heading Chinese Cabbage Seedling at Different Growth Stages
摘要
Abstract
Analyzing the quality characteristics of non-heading Chinese cabbage seedlings at different growth stages and establishing a comprehensive evaluation method for their quality is of great significance for improving the overall quality.Three varieties of non-heading Chinese cabbage,including deep purple leaf('Ziguan'),light purple leaf('Ziyu'),and green leaf('Yanqing'),were used as experimental materials to study the differences in biomass,sensory quality,and nutritional quality of cabbage seedlings at different harvesting stages.The comprehensive quality of cabbage seedlings was evaluated by the entropy method.The results showed that with prolonged growth time,the biomass increase rates were different among varieties.Compared with the three-leaf stage,the fresh weight increased by 65%to 124%at the five-leaf stage.In terms of nutritional quality,the content of pectin and oxalic acid showed a significant decrease with increasing growth time,while the content of nitrate increased significantly at the five-leaf stage.In terms of sensory quality,the comprehensive fresh-eating sensory scores of the three varieties are the highest at the three-leaf stage,and the differences in cooked-eating sensory quality at different stages are relatively small.The comprehensive quality evaluation results indicate that the comprehensive nutritional quality score of the three-leaf stage cabbage seedlings is the highest,but the degree of advantage is limited.Moreover,the total score of the five-leaf stage is the highest.Therefore,to increase yield,the cultivation period can be extended to the five-leaf stage.This study can provide a theoretical reference for clarifying the suitable cultivation period for cabbage seedlings.关键词
