Density, size and maturity of buckwheat seeds, temperature, radiation, ultra-violet light, GA, 6-BA , microelement were the dominant factors; Main study on sprout status, sprout ration, vigor index, plant height, yield, vitamin C, total flavonoids content and variation of correlated enzyme, in order to find out the correlated parameter that all factors affected the buckwheat, then we could guide the production.

中文摘要：本试验以种子的千粒重、大小和成熟度，温度、光照、微量元素、赤霉素、6-BA、紫外光等为主要影响因子，对苦荞种子的发芽势、发芽率、活力指数，苦荞芽菜的株高、产量、维生素C和总黄酮含量以及相关酶活性的变化进行了研究，期望找出各因子对苦荞芽菜生长和生理影响的相关参数，以指导生产。

Amaranthus retroflexux L. and Trifolium repens L.. The result showed that three different extracts inhibited the germination rate of seeds and inhibited the growth of seeding and young root. The experiment showed that White clover existed obvious allelopathy and autotoxidity effect.

结果表明，地上部分水浸液、挥发物和根系分泌物显著抑制了反枝苋、苘麻和自身种子的发芽率，三部分提取物显著的抑制了苘麻、稗草和自身种子在萌发过程中芽长和根长的生长；试验表明白三叶草存在明显的化感作用且有一定的自毒作用。

The results indicate that Ca(superscript 2+) and GA3, single or combined application treatments, promote cucumber seed germination treated with P. harmala alkaloid, increase germination rate, germination vigor and index; as well as α-amylase, protease, lipase, isocitratelyase, nicotinamide adenine dinucleotide kinase and Ca(superscript 2+)-ATPase activities; and GA and CaM content in cucumber seeds; but decrease abscisic acid content. The synergistic effects of combined Ca(superscript 2+) and GA3 on increasing GA and decreasing ABA are oberseved compared with Ca(superscript 2+) treatment.

结果表明，Ca(上标 2+)和GA3单一及复合处理可促进骆驼蓬生物碱处理的黄瓜种子的萌发，使黄瓜萌发率、发芽指数和活力指数提高，萌发种子的α-淀粉酶、蛋白酶、脂肪酶和异柠檬酸裂解酶活性及赤霉素和钙调素含量增加，烟酰胺腺嘌呤二核苷酸激酶和Ca(上标 2+)-ATP酶活性增强，脱落酸含量降低；且Ca(上标 2+)和GA3复合处理对GA含量的提高和ABA含量的降低与Ca(上标 2+)单一处理比较呈显著的加成作用。

However, due to predatorily digging roots for a long time, the wild licorice resources are facing with exhausting. The cultivated area of licorice is bigger and bigger, good quality seeds are essential to get good quality medicinal materials.

随着人工栽培甘草的面积的加大，对种子的需求也不断增加，而甘草种子的质量决定着甘草成品的质量。

The germinating tests were performed on Fraxinus velutina seeds from saline land and none-saline land under different NaCl stress. The germination indexes and the biochemical indexes of the seedlings were measured for studying the differences of germination abilities and protective enzymes between two kinds of the seeds under NaCl stress.

将盐碱地和非盐碱地上采集的绒毛白蜡种子在不同盐胁迫下做发芽试验，测定两类种子的发芽指标和幼苗的生理生化指标，比较它们在不同盐胁迫下的发芽情况、幼苗保护性酶活性、可溶性蛋白和丙二醛含量的差异。
