花芽

The process can be divided into 6 stages of differentiation: early, involucrum, single flower, perianth, androecium, and gynoecium.

花芽形态分化可分为花芽分化初始期、总苞分化期、花原基分化期、顶花花被分化期、雄蕊分化期和雌蕊分化期6个阶段。

It took 180 days from planting to bulbil differentiation, in which stage the accumulation of dry matter and uptake of N, P and K everyday were less. It took 52 days from bulbil differentiation to harvest, in which stage scape growed and bulb extended, the accumulation of dry matter and uptake of N, P and K everyday increased rapidly.

从播种到鳞芽花芽分化期(180d)，大蒜干物质日均积累量相对较低，对氮、磷、钾的吸收量分别占整个生育期的30.7%、36.8%和46.1%；从鲜芽花芽分化期到收获(52d)，蒜薹伸长、鳞茎膨大，大蒜干物质日均积累量迅速增加，对氮、磷、钾的吸收分别占整个生育期的69.3%、63.2%和53.9%，到收获前期干物质积累和养分吸收达到高峰。

The promotion of flower bud differentiation and enhance the quantity and quality of flower buds.

促进花芽分化，提高花芽的数量和质量。

For make the reasonable measures of florescence control,this article reveals the physiological characteristics of Syringa oblata flower bud differentiation.Changes of soluble protein,soluble sugar,starch and nucleic acid contents in floral bud,leaf bud and leaves of Syringa oblata during its floral bud differentiation were studied.

为制定合理的花期调控措施，进一步揭示华北紫丁香花芽分化的生理特性，以不同时期的华北紫丁香花芽、叶芽及其叶片为材料，研究在花芽分化过程中可溶性糖、淀粉、可溶性蛋白质及核酸含量的变化。

When pea ( Pisum sativum L.,Alaska strain) was grown in short\|day conditions,the apical bud senescence started with the transformation of the bud from vegetative to reproductive growth.DNA fragmentation was detected during the senescence using the terminal deoxynucleotidyl transferase\|mediated dUTP nick end in situ labeling method.The cell ultrastructural changes were similar to apoptosis in animal cells:the apical meristemetic cells underwent the programmed cell death.This wa...

显微、超微结构研究表明，短日照条件下豌豆顶芽的衰老过程是从营养生长锥向花芽的转化，而用DNA原位末端标记、Caspase 8WesternBlot和 14 0bpDNA片断积累的试验结果证明，转化为花芽的整个生长锥细胞发生了编程性死亡，而且其最顶端部分细胞首先发生PCD ，而顶端周围的分生组织细胞逐渐分化出花芽的各部分，但顶芽最后并没有发育成为完整的花，所有细胞就都发生PCD ，从而顶芽衰老

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。

Research on IAA,GAs,ABA and ZRs extracts of the apical tissue of the flower and leaf bud of Redchief variety showed that in the critical period of flower bud initiation the content of IAA and GAs substances were reduced,while the content of ABA and ZRs were maintained in high level .

在过去研究苹果花芽形态分化开始时期的基础上，对首红苹果花芽孕育过程中花芽、叶芽生长点的甲醇提取物进行了IAA、GAs、ABA和ZR的分离、纯化和鉴定。结果发现，在苹果花芽孕育临界时期内，随时间推移，IAA、GAs含量下降，ABA上升，ZR保持高水平。

Only 1O-day pretreatment of germinated seeds at 5℃ or 10℃ was enough to enhance the floral bud differentiation in the spring variety'Duanye 13', whereas at least 20-day pretreatment was required for the promotion of floral bud differentiation in the winter variety'Yidianhong'. Non-vernalized'Duanyi 13'plants flowered 70 days after transplanting in a warm (above 15℃) and long photoperiod (16h) growth condition, but non-vernalized 'Yidianhong'plants did not flower 90 days after transplanting in the same growth condition as'Duanye 13'.

处理温度越低和/和处理时间越长，对花芽分化和开花的促进作用越明显；春性品种'短叶13'的萌动种子在5℃和10℃条件下处理10d就能显著促进其花芽分化，而且即使未经低温处理，并给予15℃以上的生长温度和16h的长日照条件，植株也能在播种后70d内开花；但冬性品种'一点红'则需要在5℃或10℃下处理20d以上方能显著促进花芽分化，若不给予低温处理，即使给予16h的长光照条件，在播种后90d也不能开花。

In this paper the Guinong No.5selection of Rosa roxburghii Tratt was used as material for studying the changes of the contents of ZRs ,IAA,ABA,starch,total water soluble sugar and total nitrogen at the flower bud differentiation stage.

在对贵农5号刺梨花芽分化进行观察的基础上，对花芽分化期刺梨花芽和叶芽中内源激素的赤霉素(GA1+3)、玉米素核苷、生长素、脱落酸和淀粉、可溶性总糖、总氮含量变化进行了研究。

Different photoperiods:⑴ Long-day treatment accelerated the process of flower bud differentiation and increased the numbers of the flower buds of two-crop cultivar; short-day treatment accelerated the process of flower bud differentiation of one-crop cultivar, but long-day treatment increased the numbers of the flower buds per inflorescence.

不同光周期下：⑴长日照促进二次花品种的花芽分化进程和单花序上花芽数量的增加；短日照加速了一次花品种植株花芽分化进程，而长日照促进了其单花序上花芽数目的增加。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
