查询词典 tuberization

Appropriate nutrient supply could keep higher ZT content at initial stage and higher ABA, JA and IAA content and lower GA content at middle period, which could satisfy the demand of important hormones in every stage of tuberization and keep GA/ABA and GA/JA at reasonable levels during tuber formation.

而合理营养水平供给，保持了前期较高水平的ZT含量，中期较高的ABA、IAA、JA含量和较低的GA含量，保证了块茎发育各时期对重要激素的需要，GA/ABA和GA/JA在块茎发育各时期也保持在合理的水平。

Were analyzed under different nutritional levels. The results showed that in tuber development, under- or over-supply of nutrients reduced ZT content at initial stage and IAA, ABA and JA content at middle stage, but increased GA content in the whole process, which caused GA/ABA and GA/JA to be off balance in the key stage of tuberization.

结果表明，过低、过高的营养供给，降低了块茎发育前期细胞分裂素的含量，中期细胞生长素的含量以及促进块茎发育的脱落酸、茉莉酸含量，增加了各时期促进匍匐茎发生的赤霉素含量，导致在块茎形成和膨大的关键时期，GA/ABA和GA/JA比值失衡，抑制了块茎的正常发育。

As an example, sweet potato is characterized with fleshy tuberous roots for nutrient storage. Factors directing the induction of early tuberization have been investigated for a long time in sweet potato.

块根膨大过程中的营养元素需求、形态变化、内在植物激素消长等方面，长久以来已被广泛研究，但是其基因调控机理至今仍不明确；为此，本研究欲著眼於分子层面来探究甘薯的块根形成机制。

Tuberization of sense and antisense transgenic plants grown in vitro demonstrated that four of the ten sense plant lines had a significant increase while six of eleven antisense plant lines had a significant reduction in percentage of plantlets formed tubers and number of tubers per plantlet compared with the control.

对转正反义基因植株试管块茎形成的诱导结果表明，在10个转正义patatin基因植株中，有4个株系的结薯株率和单株结薯数比其对照明显增加，在11个转反义patatin基因植株中，有6个株系的结薯株率和单株结薯数比对照明显减少。

Were analyzed under different nutritional levels. The results showed that in tuber development, under-or over-supply of nutrients reduced Zeatin content at initial stage and indole actic acid, abscisic acid and jasmonic acid content at middle stage, but increased gibberellins content in the whole process, which caused GA/ABA and GA/JA to be off balance in the key stage of tuberization.

结果表明，过低、过高的营养供给，降低了块茎发育前期细胞分裂素的含量，中期细胞生长素的含量以及促进块茎发育的脱落酸、茉莉酸含量，增加了各时期促进匍匐茎发生的赤霉素含量，导致在块茎形成和膨大的关键时期，GA/ABA和GA/JA比值失衡，抑制了块茎的正常发育。

An effective induction system forpotato microtuber induction was established with the advantages ofhigh induction frequency, large microtuber size and early tuberization.

这种诱导系统使用液体培养基，具有试管微型薯发生频率高、薯块体积大和微型薯形成早的特点。

In functional study, overexpression assay was conducted in potato. Interestingly, tuberous swelling along roots was observed in some transgenic potato lines in addition to stem-derived tuber formation. Conclusively, we propose a hypothesis to illustrate the mechanism by which IbMADS1 participates in the initiation of tuberization in sweet potato.

利用解剖切片观察并比较转殖马铃薯与野生型甘薯的根部块状膨大区域，可以发现两者在膨大初期，中柱内含的细胞数皆增多，尤其是木质部细胞出现不正常增生情形，进而扩展中柱区域；因此，我们可以初步推论在甘薯块根发育初期，IbMADS1藉著作用於根部分生组织，尤其是中柱的原始形成层，从而促进细胞分裂，并参与甘薯的初期结薯。

These results indicated that the efficient tuberization of potato could be obtained by using a half-solid medium.The half-solid medium took shorter period to tuberize,produced higher tuberizing rate,costed less and was more suitable for mass production of potato microtubers in large containers.And 0.1mg/Lpaclobutrazol could effectively promote the yield and quality of potato microtubers.But different cultivar for paclobutrazol treatment had genetic differences in microtuber inducement.

试验结果表明，两种培养基都以半固体方式培养诱导试管微型薯效果最好，结薯率高，成本低，适用于在大容器内规模化培养诱导生产微型薯；在马铃薯试管微型薯生产中，诱导条件下添加0.1mg/L多效唑，可以提高试管薯的产量和质量，但存在基因型差异。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
