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...

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.

我们对油菜良种凡育中的几个植物学问题进行了试验研究,得到了下列结果。1.油菜种子的异质性。油菜全株种子的品质,以主茎较优,分枝次之,再分枝较劣。主茎果序各部种子的品质,以中部和下部较优,上部较劣,各分枝种子的品质,以上部分枝和中部分枝较优,下部分枝较劣。其中以主茎果序中、下部种子种用品质最优。进行整枝留种试验的结果,经过整枝的植株,其茎叶显著增大,角果内籽粒数增加,千粒重增大,发芽率提高。用整枝留种的种子播种,其后代比对照出苗整齐,幼苗生长健旺,产量增加。在油菜良种凡育实践上,为了获得优良的油菜种子,在留种时,可应用主茎留种、整枝留种等方法。2.胜利油菜的传粉习性在成都地区条件下,胜利油菜的开花散粉过程,多数花朵系从傍晚开始活动。最初是花萼顶端裂开,现出柱头。其后花瓣伸出萼片之外。至次日上午,花瓣逐渐开放。约近中午花瓣展平成十字形。在十字形肘期,花药盛裂,散出花粉。约经1—2日后,花瓣复闭合成半开状。其后花瓣边缘萎缩,并逐渐脱落。胜利油菜的雌蕊发育较早。在花蕾时期雌蕊即已具有受粉能力,可以进行蕾期授粉。雌蕊受粉能力较强时期,是开花后的1—3天,约4天后下降,约6天后丧失受粉能力。胜利油菜的花在形态和生理上表现...

A method of extraction,separation and determination of the residual rogor (O,O-dimethyl S-(N-methyl-carbomoylmethyl) phosphorothionate) in vege- tables and fruits is described.The residual quantities of the rogor retained in the cabbages of different growing stages,in two-varieties of rapes and in leaves and fruits of peach tree were determined successively at intervals of the first,third,fifth and seventh day after the spraying of the insecticide. The insecticidal effects against the aphids as measured...

A method of extraction,separation and determination of the residual rogor (O,O-dimethyl S-(N-methyl-carbomoylmethyl) phosphorothionate) in vege- tables and fruits is described.The residual quantities of the rogor retained in the cabbages of different growing stages,in two-varieties of rapes and in leaves and fruits of peach tree were determined successively at intervals of the first,third,fifth and seventh day after the spraying of the insecticide. The insecticidal effects against the aphids as measured by lethal rate (in %) in respective period were recorded. It is found that at the first day after spraying the residual rogor in buds and stem of the cabbages at budding stage is about 2.5 times as that of the leaves of the same plant,while the amount of the insecticide in the whole plant at seedling stage is between the latter two.The rogor residue in Sun-li rape (cabbage type) is higher than that of the Pai-go rape (Chi- nese cabbage type).For the peaches,the rogor retained in the leaves is about 5 times as that of the fruits.The insecticidal effect agrees very well with the residual rogor in the tested samples. All the rogor residues retained in the tested samples are below I ppm. which is far below the recognized safety margin,2 ppm.

1.作者描述了一个效果较好而又节省有机溶剂的提取及分离乐果的方法。2.不同生育期青菜(四月慢)中乐果残留量的测定指出:在同株孕蕾抽苔期青菜上,苔莢中乐果含量为菜叶的2.5倍(施药一天后);同时也大于小菜期全株的含量。3.所试两种不同类型的油菜中,甘蓝型(胜利油菜)的乐果残留量大于白菜型(白果油菜)。这种差具可能由于生态的而非生理的原因所致。4.施药一天后,同株桃树上,桃叶中的乐果残留量为桃子的5倍。5.施药五天后,所测各样品的乐果残留量均小于1ppm,这个数值低于规定的安全限量2ppm。

In 1961 and during 1963 to 1965 a series of observations on Myzus persicae (Sulzer) and Hyadaphis erysimi pseudobrassicae (Davis) on cruciferous crops including seeding Chinese cabbage (Brassica pekinensis Rupr.), seeding radish (Raphanus sativus L.), cabbage (Brassica oleracea var. capitata L.), broccoli (B. oleracea var. caulorapa Pasq.), summer rape (B. chinensis L.), summer and autumn Chinese cabbage and wind-break spinach (Spinacia oleracea L.) was carried out in Peking and Tientsin by analyzing the...

In 1961 and during 1963 to 1965 a series of observations on Myzus persicae (Sulzer) and Hyadaphis erysimi pseudobrassicae (Davis) on cruciferous crops including seeding Chinese cabbage (Brassica pekinensis Rupr.), seeding radish (Raphanus sativus L.), cabbage (Brassica oleracea var. capitata L.), broccoli (B. oleracea var. caulorapa Pasq.), summer rape (B. chinensis L.), summer and autumn Chinese cabbage and wind-break spinach (Spinacia oleracea L.) was carried out in Peking and Tientsin by analyzing the composition of aphid colonies. It was found that before the appearance of nymphal alatae in an aphid colony the reproductive rate used to decline at first so that the ratio between nymphs and adults gradually decreased. When the ratio reached to a certain level nymphal alatae would soon appear in the colony. Based on this finding it is possible to forecast the flight-dispersion of aphids by determining the ratios between nymphs and adults through continuous observations.The numerical analyses indicated that in Myzus persicae (Sulzer), the ratio ranged 2.17-2.91 (95 per cent fiducial limit) or 2.03-3.05 (99 per cent fiducial limit) four to six days before the appearance of nymphal alatae. In Hyadaphis erysimi pseudobrassicae (Davis), the ratio ranged 8.56-9.76 (95 per cent fiducial limit) or 8.29-10.03 (99 per cent fiducial limit) five to six days before the appearance of nymphal alatae.

在1961年及1963—65年,我们在北京和天津对十字花科蔬菜上的两种蚜虫——桃蚜Myzus persicae(Sulzer)和菜缢管蚜Hyadaphis erysimi pseudobrassicae(Davis)——分别在留种白菜、留种萝卜、甘蓝、苤蓝、小白菜、小油菜、秋白菜,以及春天的风障菠菜上进行了系统的蚜群分析。研究表明,在蚜群中出现有翅若蚜前,繁殖力有下降趋势;因而若蚜与成蚜数量的比值亦逐渐下降。降到一定的比值,蚜群中即将出现有翅若蚜。因此,可以通过系统调查,用统计蚜群中若蚜与成蚜的数量比,来作蚜虫迁飞期的短期预测。 数量分析表明:桃蚜出现有翅若蚜前4—6天,其若蚜与成蚜的数量比为2.17—2.91(95%置信限)或2.03—3.05(99%置信限)。菜缢管蚜有翅若蚜出现前5—6天其比值为8.56—9.76(95%置信限)或8.29—10.03(99%置信限)。
