甜高粱新品系YT002在江苏种植的产量形成和器官建成动态特征分析
Dynamic Characteristics of Yield Formation and Organ Growth of Sweet Sorghum New Line YT002 in Jiangsu Province
摘要
Abstract
An excellent sweet sorghum new line YT002, which was bred by Chinese Academy of Sciences, was used to study the yield formation, growth and development, and the dynamic characteristics of organ growth in Nanjing area. The results showed that the jointing stage, booting stage, heading stage, stem maturation stage, and seed maturation stage of YT002 were respectively about the 20th day, the 98th day, the 108th day, the 118th day, and the 147th day after seedling emergence. The highest plant fresh weight of sweet sorghum appeared at booting stage, which was the most suitable stage for harvesting sweet sorghum as green forage. The highest stem fresh weight and the maximum sugar content in the stem appeared from 10 to 32 days after heading, and it was the most suitable stage for harvesting the stem of sweet sorghum.关键词
