Chrysanthemum has head-like inflorescence called capitulum, a dense cluster of stalkless flowers. Capitulum contains two different kind of floret called ray floret and disc floret. Most of Chrysanthemum has both of them.

The distribution of the qualitative characters The performance of the 39 chief qualitative characters were observed and recorded,according to the test method of morphological characters in the .The results of distribution proportion of each character in cultivars group showed that the distribution of 32 characters(number of ray flower rings,floret curliness,shape of leaf base,size of stipule and so on) were very asymmetrical with near or above 70%cultivars concentrated upon one or two performance, however,the distribution of the other 7 characters(floret type,surface color of outer floret,back color of outer floret,color of disc floret,claw in base of sinus between lateral lobes,stem erectness and stem color) in the cultivars group were relatively symmetrical.

The specific primer was further designed. Using the ray floret as material, after RT-PCR, T-A clone and sequencing, a 732 bp sequence was obtained.

To investigate the relationship between delayed fluorescence change and chlorophyll content of Gerbera hybrida ray floret during its development (from P1 period to P6 period), delayed fluorescence analysis of Gerbera hybrida ray floret during its development was done.

以非洲菊Gerbera hybrida為研究對象，對其生長發(fā)育過程（P1-P6期）中外輪舌狀花進行延遲熒光（delayed fluorescence国产伦频网， DF）分析国产日韩入口一区二区三区，并利用激光共聚焦成像系統(tǒng)對其各期表皮細胞中葉綠素的分布和相對含量進行檢測，以研究非洲菊外輪舌狀花發(fā)育過程中延遲熒光改變與其葉綠素變化的關(guān)系精品久久久一级毛片。

Ray florets elongated faster than disc florets from phase P3, when tetrads of haploid microspores appeared, and the pigmentation of the ray floret began when the pollen grains showed germination apertures in the disc florets of the first whorl. The effects of light, sugar and GA3 on flower growth and development were investigated in vitro. Inflorescences in the P2 phase or later could grow and bloom in vitro, and sucrose, GA3 and light promoted flowering.
