花芽

Once the panicle stops developing, all anthers are in developing from 4th stage to early binucleate for about 1 month.

台湾泡桐之花粉发育与花序之开展有关，当花序中花芽仍处在继续生长状态时，花粉母细胞、四分子及单核初期至中期均可在同一花序之花芽中观察到。

This paper studied the process of the floral differentiation of Ficus carica L."Brunswick" with paraffin cut method. Atddition to that, the change of hormone levels and nutritions were also studied. The main results were as follows: 1. The dormant bud of Ficus carica L.

本文以布兰瑞克无花果为研究材料，采用石蜡切片的方法研究了其花芽分化的形态学过程，并在此基础之上对其激素含量的变化规律和营养物质含量的变化规律进行了分析，同时初步确定了激素、营养和花芽分化之间的相互关系。

The results of changes of endogenous hormone contents at early stage of floral differentiation in cotyledonary nodes of cucumber seedlings after decapitation were as follows: The contents of IAA and ZT in cotyledonary nodes of the cucumber seedlings within 0~4 d after decapitation decreases while the level of GA3 first increases then declines within 1~3 d, after that it increases again.

对花芽分化初期子叶节中内源激素质量分数的测定表明，IAA质量分数在花芽分化初期处於较低水准，ZT质量分数呈下降趋势，GA3质量分数则出现升-降-升的波动状态。

Bud differentiation rate with daubing or spraying 25mg/kg 6-BA was more 8.3% than that of the control

3在高山低温催花过程中，25 mg/kg 6-BA涂抹或喷施可有效地促进花芽分化，花芽分化率比对照提高8.3

When the bud growed to 0.5centimeter before the the gynandrous primordium was formed, the male were easily induced by GA_3among apomixes species.

GA_3诱导苎麻属全雌性无融合生殖种产生雄花的试验表明，花芽分化至雌蕊原基分化形成之前(花芽长度0.5cm左右)比较容易诱导性转换。

The optimal way for inducing floral buds is to preculture the plantets on 1/2MS medium supplemented with 0.5mg/L ABA and 0.5mg/L PP333 for 35 days, then transferred them onto 1/2MS medium supplemented with 1.0mg/L PP333 and 0.1mg/L TDZ. The frequency of floral buds induction increased sharply reaching 62.2% during a period of 150 days. All the mediums were added to 30g/L sucrose and 9g/Lagar.

通过筛选，诱导金钗石斛花芽形成效果最好的培养方法是：以1／2MS附加蔗糖30g／L，琼脂9g／L，活性炭0.5g／L为基本培养基(pH5.6～5.8)，将组培苗在加有PP_(333)0.5mg／L+ABA0.5mg／L的培养基上预培养35d后，再转入到附加TDZ0.1mg／L+PP_(333)1.0mg／L的培养基中。150d内统计的花芽形成率高达62.2％。

GA3 contents, POD activities and invertase activities started to increase significantly while IAA contents started to decrease significantly when plants entered the critical stage of flower-bud differentiation; GA3 contents, POD activities and invertase activities emerged high apex value while IAA contents emerged low apex value when plants entered stage of primar...

当植株进入花芽分化临界期时，叶片中GA3含量以及POD和转化酶活性均开始剧增，而IAA含量开始剧减；当植株进入第1侧花茎原基分化期和第2～3侧花茎原基分化期，叶片中GA3含量和POD、转化酶活性均出现一高峰值，而IAA含量出现一低峰值。可见，青花菜侧花茎每一级的花芽分化要求较高含量的GA3、较低含量的IAA和较高活性的POD、转化酶。

In protected conditions the time of flower bud differentiation of peach is from middle July to the end of September. The majority of flower bud primordia are formed from end of July to middle September.

结果表明：保护地桃花芽分化时间从7月中旬到9月下旬，7月末到9月中旬是早醒艳桃花芽集中分化期。

In the following spring,although the treatments did not affect the number of flower buds produced per tree,branches that were deflowered in the previous spring carried significantly more flower buds than did branches which had cropped.

虽然在疏花处理之间不同部位疏除花序没有影响单株花芽总数量，但是，每株树前一年春季疏花的部位比未疏花、结果的部位极显著地增加了花芽数量(SED=11.6)。

The result showed that the ethylene content in upper organ of ramie plant is higher than in lower organ. The ethylene content in leaf and stem apex is higher than flower bud. The ethylene content in ramie plant with female flower is higher than ramie plant with androgynary in stem apex, leaf and flower.

结果表明：乙烯在苎麻体内分布总趋势是自上而下依次减少，上中部器官乙烯含量大于下部器官，其中茎尖和叶片乙烯含量大于花芽，性别表现为雌性的苎麻在茎尖、叶和花芽中的乙烯含量都大于性别表现为两性的苎麻。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.
