Tetraploid embryo can be used as a power tool on life science such as on the research of mechanism in the inchoate embryo development which regulatory the cell volume, mumber and cleavage rate. Tetraploid embryo can also be used to change the ratio of genome of parents on the progeny; More importantly we can obtain completely ES cell-derived mice through tetraploid embryos complementation and the ES mice is significance in analysis of gene function and built disease mouse modle.

在生命科学研究中，四倍体胚胎可以作为研究机体发育的有力工具，例如，用它来研究早期胎儿发育过程中调节细胞体积、数目以及分裂速率的机制，也可以用它来改变双亲基因组在子代中的分配比例；更为重要的用途是通过四倍体补偿作用获得完全由ES细胞发育而来的个体，ES小鼠的获得对基因功能的分析、疾病动物模型的建立有十分重要的意义。

Vegetative agriculture is a kind of productive system, which concentrates mainly on the production of vegetative organs such as stems and leaves of plants including herbages, green fodder, vegetations, flowers, teas, tobaccos, as well as rhizome and fibre crops. The principal difference between the traditional agriculture and vegetative agriculture is that the former focuses on the productivity of the seed in the whole growing period and the latter focuses on the productivity of available nutrients at the different growing stages of plants.
