Smearing apical point with a mixture of 0.2% colchicine plus adeps lanae and 1.5% DMSO was also effective with doubling frequency 14.0%. Dripping the apical point of plantlets with trifluralin has also been tested, and it showed effective in inducing tretraploid from double haploid, but obviously delayed plant growth.

本试验还用具有抗微管形成的除草剂氟乐灵进行黄瓜幼苗滴苗加倍试验，试验结果表明，在进行黄瓜双单倍体诱导纯合四倍体时，氟乐灵具有使染色体加倍的功能，但同时也具有延迟处理植株生长的作用。

Tetraploid induction from double haploid was also studied, and a desirable result has been obtained. Dripping the apical point of plantlets with 0.2% colchicine plus 1.5% DMSO was a suitable treatment with doubling frequency 18.2%.

其中0.2％秋水仙素+1.5％DMSO滴苗处理，效果较明显，加倍频率达18.2％。1％秋水仙素+羊毛脂膏+1.5％DMSO涂抹生长点试验，加倍率为14.0％，由于此法田间工作量小，不失为双单倍体诱导纯合四倍体较好的方法。

It helps to understand some evolvement processes of species, especially in dynamical system. For instance, studying the growth of cod fish simulation of wolf in Alaska, relationship between death age and relatives, evolvement. of species, evolvement process of competition, reproduce and natural selection of haploid, and one-species cellular automata model based on the Penna model was founded on a lattice of two dimensions.

利用Penna模型有助于理解一些生物演化过程，尤其是在种群动力系统中发挥了重要作用，如北极鳕鱼生长的研究，Alaska狼群模拟，近亲遗传死亡年龄之间的关系，种群的演变，单倍体种群的竞争，繁殖，自然选择等种群演变过程，二维格子上建立基于Penna模型的单物种元胞自动机模型是Penna模型与格子结合的早期文献。

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.

研究表明，分化完全的舌状花在P3期、即花粉细胞四分体出现之后长度超过盘状花，在盘状花的雄蕊出现具有萌发孔的花粉粒之后，舌状花开始着色。P2以后的花序经离体培养可以开放，光、糖和GA3对花序的生长和开放有显著的促进作用。
