Self-compatibility and open pollination compatibility among different fine plants provide theoretical basis for its further application and further selection of new varieties. The results showed the optimal medium for germination of L. caerulea pollen was 27.5% sucrose ＋ 100 PPM boric acid with a pH value of 6.0. On this medium, the superior individuals L1, L2 and L3 had the pollen germination rates of 53.4%, 50.9% and 51.6%, respectively. The three superior individuals had no significant differences in the quantity of germinated pollen tubes, which ranged from 1 to 4. The three excellent single plants were the most likely to germinate a single pollen tube, accounting for 83.3% of the pollen germinated and 89.6% of the pollen germinated. Therefore, in production, it is necessary to plant L1 with a certain amount of pollination trees or plant it together with multiple species, to improve its yield. On the contrary, L2 and L3 have no need for pollination trees theoretically, but whether the fruits obtained by self-pollination and outcrossing differ in quality still needs further study.展开更多
用Sephadex G-25、DEAE-Sepharose Fast Flow和Sephadex G-200方法分离纯化家蚕头部中的乙酰胆碱酯酶(AChE),以有机磷化学农药为阳性对照,比较分析几种天然产物对AChE纯酶液与粗酶液的抑制效果。结果表明,经过一系列步骤的纯化,最后所得...用Sephadex G-25、DEAE-Sepharose Fast Flow和Sephadex G-200方法分离纯化家蚕头部中的乙酰胆碱酯酶(AChE),以有机磷化学农药为阳性对照,比较分析几种天然产物对AChE纯酶液与粗酶液的抑制效果。结果表明,经过一系列步骤的纯化,最后所得AChE是纯度较高的酶液,并且纯化后的AChE对抑制作用更敏感。同时实验选取的大部分天然产物提取物对纯化后的AChE都有一定的抑制作用,其中绣线菊乙醇提取物对纯酶的IC50达到了0.091×10-3g·mL-1。展开更多
