The Changing Regularity of Soluble Sugar in Gains of 'Xiangnongtianyu 2'and Its Yield Correlation with Agronomic Characteristics
摘要
Abstract
To identify the best edible period and the harvest time of sweet corn and the relationship between their harvest yield and agronomic traits,Xiangnongtianyu 2 (Normal cytoplasmic) and S-type diamond Xiangnongtianyu 2 (male sterile cytoplasm) were used as experimental material,the change regularity of sweet corn soluble sugar contents at different days after pollination were analyzed.The results showed that the soluble sugar contents reached the maximum at 22 days after pollinated,there were 139.0 mg/g and 140.7 mg/g respectively for the two varieties S-type diamond Tianyu 2 and Xiangnongtianyu 2.this time could be used as their best food period.The harvest time for sweet corn could be set at 28 days after pollinated when the effective accumulative temperature reached at 394℃.There was no significant difference between the yields of the two sweet corn types according to the correlation analysis of yield and agronomic traits,their yields were 10 694.4 kg/hm2 and 10 277.8 kg/hm2 for variety S-type diamond Xiangnongtianyu 2 and Xiangnongtianyu 2 respectively.All of the two sweet corn types could be used in the actual production.关键词
