摘 要 ：本研究运用田间和盆钵试验,观察了甘蓝型油菜(B.napus)角果生长的基本特点,探讨了不同氮水平与角果发育的关系。结果表明,角果生长发育进程呈“S”型曲线,即含明显的生长缓慢期、生长优势期、物质积累优势期和衰老期;氮水平间角果面积增长速率的差异达极显著的正相关(r=0.9091~(**)),单株角果面积与籽粒产量亦呈极显著的正相

Abstract:The principal characters of rape(B.napus)pods growth and relationship between nitrogen levels and pods productivity were both studiedin field and pot.The pods growth process makes a big S curve thatshows a four-stage development……stages of slow growth,grand growth,grand accumulation and aging.Appl
