标题 中国紫堇属鳞茎紫堇组的研究。

In this study,medium effects on bulbing varied with varieties.

对于徐州白蒜，在无激素培养基上，具有83.1%的鳞茎形成率。

Results of culture in vitro showed that specific environment conditionswere needed for bulbing.

离体培养结果已表明，大蒜鳞茎形成需要特定环境条件的诱导。

The co-effect of temperature and photoperiod treatment on garlic bulbing ratio of garlic were significant.

生长温度与光周期处理对大蒜鳞茎膨大比率互作影响明显。

So,it is suggested that decreasing of iPA/ABA and GA/ABA andincreasing of IAA/ABA simulaniously are the characteristic changes of hormone at the beginingof bulbing.

因此，作者认为，iPA/ABA和GA/ABA下降，同时IAA/ABA上升，是大蒜鳞茎形成起始的内源激素平衡变化特征。

This study can be summarized as follows:the suitable bulbing conditions are:〓+30mg/1sucrose at 20-25℃,under 12 hours day for Xuzhou White,and〓+1.0mg/1〓+90-120mg/1sucrose at 25℃,under 16 hours day for Taicang White.

在添加〓1.0mg/1的〓培养基上，徐州白蒜和太仓白蒜分别有42.1%和22.4%的鳞茎具2-3个鳞芽，这一绿体很小的试管苗即发生分瓣的现象尚未见有其它研究报道。

The results showed that: boltings and unboltings were different in the same period. The soluble protein and free amino acid were higher in unbolting onions, the soluble sugar, C/N and POD activity were higher in bolting onions on bulbing period.

结果表明：同一时间，抽薹植株与未抽薹植株存在一定的差异；鳞茎形成期，未抽薹植株游离氨基酸与可溶性蛋白质含量较高，抽薹植株可溶性糖含量、C/N值及POD活性较高。

These towers differentiate and form small bulb by two ways: one way is that towers begin to differentiate from their center ; another is that towers begin to differentiate from the tops of towers or their sides and appear small sunken concaves.

这些突起进一步分化为小鳞茎是通过两种分化方式：一种是先从突起中央出现分生细胞团开始分化的；一种是先从突起的顶端或一侧出现小凹沟开始分化的。

Finally, we test the cut flower stages. In experiment, the flower buds began greatening obviously in July. The flower bud has exceeded 3 cm already, and the number has increase to 3 already during October.

试验中，明显可看出花芽於7月份开始变大外推，而於10月份花芽已超过3 cm且数量已增加到3个，隔年2月花芽已冒出鳞茎颈部。

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
