A gross anatomical study of flower bud differentiation in a whole rape plant (Brassica napus L.) was made throughout its growing period. The main results obtained are summarized as follows:1. On the same plant,the higher the branch grade, the later the flower bud differentiation started.On the branches of grade No. 1 flower bud differentiation started from below upward and from above downward with the terminal node and the highest node of one third of the total nodes from the base as starting points.On the branches...

A gross anatomical study of flower bud differentiation in a whole rape plant (Brassica napus L.) was made throughout its growing period. The main results obtained are summarized as follows:1. On the same plant,the higher the branch grade, the later the flower bud differentiation started.On the branches of grade No. 1 flower bud differentiation started from below upward and from above downward with the terminal node and the highest node of one third of the total nodes from the base as starting points.On the branches of grades No. 2-5 flower bud differentiations were basipetal.2. On the branches of grades No.land 2 flower bud differentiation proceeded at the early growing stage,at a low rate of speed and with a small quantity of floral primordia.At the elongation stage, flower bud differentiation of all branch grades proceeded, at a high rate of speed and with a large quantity of floral primordia.3. Most of the floral primordia differentiated on the main stem and its branches of grades No. land2before the elongation stage blossomed and bore fruit, whereas the floral primordia differentiated at the elongation stage scarcely bore fruit. Consequently, measures should be taken to promote flower bud differentiation at the early growing stage and check it at the elongation stage. This might be beneficial to the increase of the number of silique and thereby the raising of seed yield.

在油菜整个大田生长期间,分期镜检全株生长点的花原基分化。结果表明:茎级愈高,花芽分化开始愈迟,同一茎轴上,各分枝开始花芽分化的次序则因枝位而异。在本试验条件下,抽苔前的油菜,一、二级分枝花原基的分化速率较慢,分化数量较少,但主茎及其上部一、二级分枝在此时分化的花原基多数能开花结实。当油菜进入抽苔至开花期,各级花原基分化的速率最快,分化数量亦最多,但大多数均不能开花结实。因此,在长江下游的类似生态条件下,当油菜抽苔前适当促进花芽分化,并在抽苔期控制花芽的发生,对增加油菜产量可能具有重要的意义。

30 day-old tissue-cultured grapes were inoculated with Glomus epi-gaeus during transplanting from test tubes to containers. 3 weeks after inoculation, in the cortical cells of grape roots were found arbuscules.At 6 weeks, they began to collaspe and a lot of vesicles were produced inter and intracellularly. At the same time, the shoot height and root collar diameter were markedly increased than those of non-inoculated ( P<0.001 and P<0.01 respectively ) . 45 days after inoculation, the grape plant-lets were transplanted...

30 day-old tissue-cultured grapes were inoculated with Glomus epi-gaeus during transplanting from test tubes to containers. 3 weeks after inoculation, in the cortical cells of grape roots were found arbuscules.At 6 weeks, they began to collaspe and a lot of vesicles were produced inter and intracellularly. At the same time, the shoot height and root collar diameter were markedly increased than those of non-inoculated ( P<0.001 and P<0.01 respectively ) . 45 days after inoculation, the grape plant-lets were transplanted from the containers to the nursery. They con-tinued to keep the growth advantage over the noninoculated control, in spite of their more serious infection by the disease of Plasmopara viticola than the control. Analysis of the leaves sho wed that the total sacchari -de content of inoculated grape was higher than the control, which benefited the development of leaf disease.

本文报道了用VA菌根真菌地表球囊霉(Glomus epigaeus)对30天苗龄的‘先锋’葡萄组培苗在移栽同时进行人工接种的技术和生长效应。接种20天后,幼苗根皮层细胞内出现有丛枝结构,6周后形成大量的泡囊。菌根感染率达90%。接种35天后的组培苗,平均苗高、根径(幼苗茎基部直径,下同)和每株叶面积比不接种的对照分别大42.8%、7.6%和62.9%,经t检验差异显著(P<0.01或 P<0.001)。接种45天后的组培苗移栽到大田生长二个月后的结果表明,其苗高、根径和叶面积比不接种的对照分别大29.2%、21.7%和18.2%,经t检验差异性均显著(P<0.05)。植物化学分析结果表明,接种VA菌根的植株叶部含糖量比对照为高,对葡萄霜霉病(Plasmopara viti-cola)感病也较严重。但由于葡萄苗木前期生长健壮,叶面积大,所以苗木生长量仍比不接种的对照要大。

Unfertilized cotton ovules were removed

将未受精的棉花胚珠漂浮培养在加有不同植物激素的BT培养基上,培养48小时或96小时后,用扫描电镜观察纤维发育情况,以及测定胚珠内IAA氧化酶活性变化及内源ABA的含量变化,并和同一时期的大田生长的胚珠进行比较。结果表明:IAA+GA_3是最佳激素组合。在这种激素组合的培养基中培养的未受精胚珠,在纤维发育、酶活性变化等方面,均与大田生长的胚珠相似。这一激素组合还能抑制离体胚珠内源ABA的增长,但同一时期的大田生长的胚珠,其内源ABA含量却相对要高。
