| 摘 要： | 以天津市农业高新技术示范园区最新引进的芹菜品种"YZ09-16"为试材,对其重量、高度、叶柄长度、叶柄粗度、叶片数目和发生分蘖数量等指标进行观测,并对结果进行Logistic生长曲线方程拟合。结果表明:芹菜的生长发育与定植时间之间的关系可以用Logistic曲线方程表示,并且达到了极显著水平。各个指标生长都呈现单S曲线,各个曲线的拐点出现时间是其生长的关键时期。

| Abstract: | Latest varieties of celery 'YZ09-16' was used as test material from Agricultural High-Tech Demonstration Zone in Tianjin City.The weight,height,petiole length,petiole diameter,leaf number and tiller number etc index of celery 'YZ09-16' were observated and measured,and the results were fitted using growth curvilinear equation of Logistic.The results showed that the relationship between growth and planting time can use logistic growth curve to express,which reached significant levels.The growth curve were all... |
