Second, tetraploid Chinese cabbage cotyledon regeneration capacity and its relationship with endogenous hormones
Small correlation coefficient R = 0.6571,[link widoczny dla zalogowanych], and endogenous IAA content in a correlation coefficient R = 0.0854, and ZRs / IAA's correlation coefficient R = 0.9428. Tetraploid cabbage under the same formula that regeneration and endogenous hormone content of the strength of correlation between the size was not significant,[link widoczny dla zalogowanych], and ZR / IAA significantly related to size. * 28 * Nanjing Agricultural University, Volume 3 of 29 discussion of adventitious buds used to compare the rate of regeneration has been reported _8j. However,[link widoczny dla zalogowanych], the main factors affect the regeneration capacity of the material genotypes and explant types. Explants of different responses to exogenous hormones, and endogenous hormone synthesis and metabolism differences between closely related. This test compared to formula 5 for the medium autotetraploid Chinese cabbage shoot regeneration rate, the strength of the reproductive capacity. Regeneration of Chinese cabbage, the hormone is considered to be an important factor, when the tissue cytokines and a high ratio of auxin, the easy induction of bud differentiation ��. LUO Qiong, etc. �� believes that cultivating rice mature embryo, the regenerative capacity of endogenous hormones on the level of significant impact,[link widoczny dla zalogowanych], explant types, the different components of endogenous hormones,[link widoczny dla zalogowanych], there are differences in regenerative capacity. The results showed that the regeneration capacity and Endogenous IAA content of ZR and the correlation was not significant, with the ZR / IAA significantly correlated, which is consistent with previous studies. Of explant regeneration capacity of endogenous hormones and the relevance of the choice of the explant and improve the regeneration frequency is important. Determination of training materials, tests found that the diploid endogenous hormone in the extra material in the process, IAA and ZR content increased accordingly, but the rate of increase is different for different materials. Tansu Ying �� to 2 groups, etc. Second, tetraploid watermelon pollen hormone zR content that: two tetraploid varieties of pollen ZR contents were two diploid species of 2.15 and 1.73 times. : This may be doubled and plant material in the course of larger plant organs and tissues, biochemical composition, and secondary metabolism increased.
