| 利用特效植物营养素（SPNE）分别喷施迟菜心2 次、1 次，用清水喷施作对照，首次探讨喷施次数对迟菜
心当代淀粉酶活力与产量的影响。将喷施SPNE 2次和对照的种子进行了分析，研究了SPNE 的表观遗传效应对后
代幼苗过氧化物酶（POD）活力的影响。结果表明，SPNE 喷施增城迟菜心后，淀粉酶活力显著提高，迟菜心产量大幅
度提高，且随着喷施次数增加，两者对应增加，喷施2 次的比喷施1 次的高，喷施1 次的比对照高，相关分析结果表
明，淀粉酶活力与迟菜心产量呈正相关。SPNE 喷施迟菜心2 次后种子也比对照大幅增产，种子千粒重增加，发芽势
显著增加，种子后代活力增强。幼苗的叶面积更大，根系更发达，孕韵阅活力极显著提高，抗逆性增强，长势更佳。同时，
进一步探讨了SPNE 在迟菜心后代的表观遗传效应产生机理。 |
| 英文摘要: |
| TTC staining, BTB indicator staining and red ink staining were used respectively to evaluate seed
viability of Gardenia jasminoides Ellis from five habitats. Influences of culture bed (vermiculite, gauze, paper, sand)
and temperatures (30,25,20,15mtemperature and 30/20, 25/15 variable temperature) on the germination rate were
examined, and germination conditions were optimized to investigate the optimal seed viability test methods and the
relationship between seed viability and germination rate for Gardenia jasminoides Ellis. The results showed that BTB
indicator method is the best one for seed viability determination, and the filter bed is the best medium in seeds
germinateon. Gardenia seeds could reach the highest germination rate when they are incubated at 30 益. Since the
correlation coefficient is 0.979 for viability determined by BTB indicator and germination rate of gardenia seed, a
significant positive correlation was proposed for gardenia seed viability(X) and germination rate(Y), and the regression
equation was Y =1.219X-0.199. |
