Three Varieties of Zea Mays——"Shuangyao 80", "Qundan 105" and " Danyu 6" were used in the experiment. The female flowers were bagged to protect them from being pollinated bafore tasseling. Artificial pollination was carried by 5 treatment, namely, complete pollination, 2/3, 1/2 and 1/3. pollination and non-pollination during the silking stage. Results showed that the decrease of the sink capacity may result in the increase of soluble sugar content in leaves and stems and the dry matter in stems, while...

实验共采用三个玉米品种——双跃80、群单105和丹玉6号。玉米开始抽雄时将雌穗用纸袋套起,防止受粉。果穗花丝抽出时,进行人工授粉,包括完全受粉,2/3花丝受粉,1/2花丝受粉,1/3花丝受粉和完全不受粉5种处理。在受粉后的不同时期测定各叶位叶和不同茎段的可溶性糖含量、光合强度、呼吸强度、籽粒产量和植株干重。结果发现减少玉米库容量可以导致各叶位叶可溶性糖含量不同程度的增大。与此同时,玉米叶片的光合强度呈不同程度的降低,而其呼吸强度则相应提高。玉米茎的可溶性糖和干重也具有不同程度的增大,籽粒产量则随库容量的减小而降低。一般认为禾谷类作物的籽粒产量与受粉后的光合强度、光合时间以及可以作为籽粒利用的早期贮存物质有关。根根近代植物生理学的研究,得知禾谷类作物产量与籽粒容量[贮存能力,一般称为库(sink)]也有密切关系,并且发现,籽粒容量与叶片光合产物供应量[供应能力,一般称为源(Source)]有关。在稻、麦等作物的库源关系的研究中指出,源受库支配,库大源强,库小源弱。近年对玉米的库源关系的研究也有一些报道,Kiesselbach(1948)与田中明等(1972)指出,玉米的库源关系类似稻、麦,源受库支配,只要将玉米...

17 representative wheat cultivars and 3 new lines were grown in a 3-replicate, randomized block layout in 1983~1984 and 1984~1985 crop seasons,and evolutionary changes in the sink-source and yield as well as the components and other characters were studied.It was showed that the total leaf area per shoot increased, and that the change of vertical distribution of leaf area occurred. LAD, leaf chlorophyll content, the ratio of A/B and sink capacity per grain and per ear of current cultivars were significantly higher than those of proceded ones. There was no difference in biomass per unit area at harvest and phyotosynthetic rate among various cultivars. Grain yield of current cultivars depended much on the amount of dry matter accumulated after anthesis. The increase in grain yield was prodominently attributed to the enhancement of harvest index. Plant height and spikes per square me?re decreased with the improvement of wheat. Results from this study suggest that further yield advanccs could be attained by increasing not only sink but also source.

对长江下游地区50年代以来先后推广的17个代表品种和3个新品系的源-库和产量性状的变化进行了两年研究。结果表明,随品种更替单茎叶面积增加,叶面积重心上移。近期品种叶片叶绿素含量和A/B高于地方品种,但光合速率差异不大。单穗、单粒库容和收获指数随品种更替而增加,但株高和单位面积穗数减少,单位面积生物量没有明显增加。地方品种前期光合生产力高,近期品种后期干物质积累多。在现有品种基础上提高产量潜力,需在增库的同时增源。

The relationship between the growth of the shooting part and stock were investigated by grafting different varieties.It shows that the influence of underground part is more bigger than that of the shoot. There is no significant reciprocal action, between scion and stock after grafting, so we can use the root sink capacity to determine the yield of different varieties.
