油菜的千粒重是构成油菜产量的重要因素之一。它虽属数量性状遗传,但通过几年来的实践探索,我们发现栽培条件对其有很大的影响,以中熟品种甘油5号而言,栽培条件较好的,千粒重高达4克左右,反之,也可在2克上下波动。一、收获时期不同的影响1981年,我们在石佛寺公社陈德云大队同一块田作了不同收获期对油菜千粒重的影响的观察试验(品种:甘油5号),结果是:5月9日收割的,千粒重2.87克;5月12日收割的,千粒重3.23克;5月15旧收割的,千粒重3.24克;5月18日收割的,千粒重3.39克。同
One-thousandth weight of rapeseed constitutes one of the important factors of rapeseed production. Although it is a quantitative trait inheritance, but through several years of practical exploration, we found that cultivation conditions have a great impact on it, medium-maturing varieties of glycerol 5, the cultivation conditions are better, 1000 grain weight up to about 4 grams, on the contrary , Can also fluctuate in 2 grams. First, the different effects of the harvest In 1981, we Shifu commune Chende Yun brigade field with a different harvest of rapeseed thousand grain weight of the observation test (variety: glycerol 5), the result is: May 9 harvest , Grain weight 2.87 grams; May 12 harvest, grain weight 3.23 grams; May 15 old harvest, grain weight 3.24 grams; May 18 harvest, grain weight 3.39 grams. with
