The following results of the studies on some botanical problems in the seed production of rape were obtained by the authors in 1956-----1963 in'chengtu.1. The seeds of the different parts, of the rape plant, vary in quality. Usually. the seeds of the central and basal part of the apical inflorescence have the best quality. The seeds of the rape plants after pruning have better quality and give more yield than the control, 'Therefore the application of the seeds of apical inflorescences, especially those of the pruned plants for the seed production of rape is recommended.2. Under the climatic conditions of Chengtu, the opening of the flowers of the. rape plant is as follows. In the blpoming season of ijapef most flowers .begin to op'en in the evening, and become ierbs$ - shaped the next day befpre noon. At 'this., time ,tfye anthesis occurs. After 1-----2 days the petals become withered andsoon begin to drop. The pistil matures early in the bud stage, and is able to be bud pollinated, The stigma is more receptive to pollenin 1-----3 days after the opening 6f the flower. It becomes lessreceptive on the 4th day, and finally completely sterile after 6 days. The rape plant is cross-pollinated and entomophilous. but is also possible to be self-pollinated. The methods of isolating plot, isolating net and isolating bag ar.e introduced to the seed production of rape. 3. Some varieties of rape were examined and their differences in the external form and internal structure of seeds and seedlings were discussed. In the seed production of rape, when the determination of seeds is needed before sowing, it is possible to determine the above varieties by the morphological and anatomical studies of seeds and seedling.s.

The process of the yield formation of rapeseed(B.napus)wasanalysed on the basis of a series of studies.of the three yieldcomponents of rapeseed,that which has most influence on the seedyield is the number of siliques per unit area(it was estimatedthāt 10,000 siliques could give approximately 0.5kg.of seeds),whereas the number of seeds per silique and the 1000-seed weightwere of comparatively less importance.Therefore,in order to in-crease the seed yield it was necessary to increase the number ofsiliques per...

The process of the yield formation of rapeseed(B.napus)wasanalysed on the basis of a series of studies.of the three yieldcomponents of rapeseed,that which has most influence on the seedyield is the number of siliques per unit area(it was estimatedthāt 10,000 siliques could give approximately 0.5kg.of seeds),whereas the number of seeds per silique and the 1000-seed weightwere of comparatively less importance.Therefore,in order to in-crease the seed yield it was necessary to increase the number ofsiliques per unit area.The way to increase the number of siliques per unit area is toincrease the number of plants per unit area and the number of siliquesper plant.It was indicated by the path coefficient analysis that if theplanting density of the rapeseed crop was within the limit of 20,000plants/mu,the seed yield increased with the increasing of plantingdensity.This was particularly true within the limit of 10,000 plants/mu.(The optimum density of the rapeseed crop in the Yangtze Valley isabout 10,000-15,000 plants/mu)The way to increase the number of siliques per plant is to increasethe number of siliques of the primary branch,i.e.to increase the totalnumber on the main stem,to increase the ratio of formative branches,and to increase the number of available buds before the budding stage.The way to increase the number of seeds per silique is to increasethe number of ovules per silique and the percentage of fertilized ovulesso that more zygotes could develop into seeds.Since the seedling stage(before the budding stage)of rapeseed isa very important period not only for the vegetative growth but alsofor the differentiation of effective buds,it was suggested that special care should be paid to the management of this crop before and during wintertime(when the crop had been planted with an optimum sowing dateand density).However,the management of the later stages shouldn'tbe relaxed if a higher yield is to be obtained.

在油菜(B.napus)产量构成因素中,单位面积上角果数对单位面积产量影响最大,但每果粒数和粒重也有一定影响。本文是对增加单位面积上角果数,以及增加每果粒数和粒重等问题的初步分析,并在文中提出了相应的栽培技术措施。
