1·Floral bud differentiation is the basis of flowering.
花芽分化是植物成花的基础。
2·Huaguang were investigated during natural dormancy period, and some of the physiological changes in floral bud were studied.
研究了低温累积对华光油桃萌芽的影响以及花芽在自然休眠过程中几项生理指标的变化。
3·The time for flower bud differentiation and the process of floral bud development in Actinidia in Hefei district were studied in this paper.
本文研究了中华猕猴桃在合肥地区花芽分化的时期及花器形态分化的过程。
4·Based on the characteristic of floral bud emergence, the cultivars can be divided into 3 groups: early, middle and late floral budding groups.
根据各品种的现蕾特点，大致可分为早蕾型、中蕾型和晚蕾型三种类型。
5·As a result, the floral bud inducement with PP333 mainly worked in short time, and the process of accumulation also exhibited some promotion on floral differentiation.
所以，PP333诱导花芽分化主要是在短时间内起作用，但累积过程对花芽分化也具有促进作用。
6·But improper cultivation practices always pose series of setbacks, simply because physiological information on floral bud development and flowering mechanism is largely lacking.
因缺乏对牡丹花芽发育及开花生理机制的深入研究，许多的栽培实践总是受到挫折。
7·The contents of DNA and RNA went up in the middle period of floral initiation, which obviously promoted physiological flower bud differentiation.
花芽孕育期中期DNA和RNA含量的升高对于花芽生理分化有明显的促进作用。
