    This preliminary study of the influence of spikelet pruning on the quality and yield of wheat grains was carried out at Fukien Agricultural College in October 1952 through May 1953. The results are summarized as follows: 1. The number of grains increases in each spikelet as a result of pruning. 2. Size, weight, and protein content of the grain increase both with the difference in variety and the dates of planting. 3. Treated wheat plants ripen earlier. 4. The total yield decreases slightly. This...

    This preliminary study of the influence of spikelet pruning on the quality and yield of wheat grains was carried out at Fukien Agricultural College in October 1952 through May 1953. The results are summarized as follows: 1. The number of grains increases in each spikelet as a result of pruning. 2. Size, weight, and protein content of the grain increase both with the difference in variety and the dates of planting. 3. Treated wheat plants ripen earlier. 4. The total yield decreases slightly. This is probably due to the fact that the gain in weight of grains does not overcome the loss of weight by the removal of some of the spikelets,

    作者等于一九五二年十月至一九五三年五月在本校农场进行小麦花序修整的研究,结果归纳如下: 1.剩佘小穗的结实性,种子肥大性,及蛋白质含量均有提高,但提高的程度因品种和播种期而有所不同。 2.成熟期提早。 3.不同品种不同播种期,对于修整花序有不同的反应,以迟熟种的反应更为显著。 4.产量稍为减低,可能是因为千粒重的增加弥补不了粒数的减少。

    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...

    From 1960 to 1962, the authors studied the influence of summer pruning to hasten fruit-bearing of young apple trees of varieties Golden Delicious and Rail's at Hsuchow, which lies in the Old Yellow River Basin Area. The results may be summariesed as following:

    对黄河故道地区苹果幼树采取雨次夏季修剪,使原来早实、迟实品种,均能提早于定植后第三年开始结果。提早结果的生物学反应,主要是利用枝条的一年多次生长特性,在成枝的当年形成夏梢果技及腋花芽;这些后期形成的花芽,均能正常结实。根据花芽分布的部位,提出长留结果枝的修剪方法,结果以后,无碍同年生主、侧枝的生长,仍能扩大树冠正常成形。
