摘要
通过测定秦油２号角果长、宽的增长及其亮、籽粒重量变化。角果长度在花后１２—１５天定型，宽度在花后２１—２８天定型。当长度达到最大值时，宽度的增长速度达最大值；当宽度达最大值时，果壳的鲜重、干重及籽粒的鲜重也达最大值。秦油２号籽粒增重具有明显的优势。
The characteristics of pod growth of hybrid rape Qingyou No.2 were studied through measuring the length and width of pods and weighing pod skins and seeds.The results were as follows:1.Pods elongated first and reached their maximum length at about 12-15 days after flowering and maximum width at about 21-28 days.The fresh and dry weight of pod skins and fresh weight of seeds all reached their maximum values when the pods reached their maximum width.2.The seed filling of Qingyou No.2 was superior to conventional rapes.
