ResultThe differences of the effects onthe germination of 2 group seeds in afterripening and GA3treatments reached at significant level.

结果后熟、GA3处理对2组种子发芽情况的影响差异达显著水平，后熟分别使发芽率由6.67%、7.78%，提高到21.33%、33.33%；GA3处理，发芽率随GA3浓度的增加，呈现低、高、低的趋势，以GA3200mg/L处理的种子萌发效果最佳；温汤浸种、KNO3处理对2组种子发芽情况的影响差异达极显著水平，其中温汤浸种处理的种子，发芽率随水温的升高而升高，以70℃水浸种后萌发效果最优，发芽率分别由21.33%、33.33%，提高到73.33%、90%；KNO3处理组，发芽率在处理浓度为250mg/L时为最佳水平。

Seed industry of large turn, it is big trend to grow industry develop that almightiness turn; The farm crop seed industry turns and can make section taught to grow , the seed produe, sprocess and promote to expand the section the close uniting with the agriculture, becoming the technology lead first the type seed industry group, uniting the developmend meet the next the new species that modern agriculture need when producing , new technique new product of market mechanism term establishing to rise to face to the domestic and international market teach , heavy, push, the integral whole of turns of carry camp mechanism, end guarantee to teach to grow the section can stabilize a ground of growing the high producing, superior quality, many antis of new species, good and new species in distribution in section in seed.

种业的大型化、全能化是国际种业发展的大趋势；农作物种子产业化可以使科研育种、种子生产、加工、经销和农业推广部门紧密联合成科技先导型种子产业集团，联合开发符合市场机制条件下现代农业生产所需要的新品种、新技术、新产品，建立起面向国内外市场的育、繁、推、销一体化的运营机制，最终保证育种科研能稳定地培育出高产、优质、多抗的新品种，种子部门经销优良的新品种。

And the applied methods of soil seed bank in ecologic restoration for ...

本文对土壤种子库的特征、研究方法和国内外研究进展等进行了综述，探讨了土壤种子库存植被恢复和重建中的重要作用，分析了土壤种子库应用于工程创面生态生态恢复的优势，提也了利用土壤种子库对工程创面进行生态恢复的实施方法。

The results showed that, all the treatments can shorten the time of epicotyl germination of 'Fengdan', the 28 days chilling treatment was the shortest, and the next was 21 days chilling treatment and 300 mg/L GA3 treatment; in a certain range of GA3 concentrations, higher concentrations, higher seed germination index and germination rate in 'Fengdan'; the seed germination index and germination rate of 'Fengdan' after different time chilling treatments were higher than the control, in which, the treatment of 21 days chilling had the highest germination index and germination rate.

研究了不同时间的低温(4℃)处理及不同浓度的GA3处理对凤丹种子上胚轴萌发及幼苗生长的影响，结果表明：所有处理均能缩短凤丹种子上胚轴萌发时间，以低温28天处理初萌期最短，其次是低温21天和300mg/L GA3处理；在一定的GA3浓度范围内，浓度越高，凤丹种子发芽指数与发芽率越高；不同时间低温处理后凤丹种子发芽指数与发芽率均高于时照，其中低温21天处理是所有处理中发芽指数与发芽率最高的。

Integrate low temperature and ultra-dry to excogitate better method to prolong seed longevity, at the same time, we found out the optimal method of ultra-dry preservation, screen out to the excellent desiccant with low cost and good effect, validate the method of ultra-dry can use to deal with and conservation even more large numbers of tobacco seed, yet explored seed vigor comedown rule of tobacco seed, that avoid seed vigor loss prematurely.

在此基础上，把超干燥与低温保存有机地结合起来研究，找出了延长烟草种子寿命的更好方法，找出最佳的超干燥保存方法，优选出成本低、效果好的干燥剂，验证了超干燥也可用于更大量烟草种子的处理和保存，初步探明了烟草种子的活力丧失规律，有效预防了种质资源的失传，最大限度地延长种子保存寿命达25年以上。

Remember, whether its grass seeds, tomato seeds or flax seed, the plant will only be as good as the original seed.

请记住，不论其草种子，番茄种子或亚麻种子，植物才会不如原来的种子。

Drying was important for the acquisition of germinability, and drying induced precocious maturation and played some role in the transition from a development programme to a programme oriented towards germination and growth.

干燥脱水对种子萌发有重要意义，成熟脱水可以使种子由发育状态转向萌发状态，玉米种子在获得耐脱水能力之后，干燥可以使未熟玉米种子提前进入成熟状态，终止与发育有关的代谢，开始与萌发有关的代谢。

BA and GA3 in proper concentrations were the effective hormones to induce the germination of germ tube and the germinating rate was 3.3%. When treated with 6-BA + GA3 + IBA, the germinating rate doubled compared with single hormone treatments. However, the germ tube didn't form haustorium afterwards.

结果如下： 1、适当浓度的6-BA和GA3能够诱导肉苁蓉种子萌发形成芽管，芽管萌发率仅为3.3%，6-BA + GA3 + IBA组合使种子芽管萌发率提高2倍，激素只能诱导肉苁蓉种子萌发芽管，不能进一步诱导肉苁蓉种子形成吸器。

After preliminary study, it is found that environmental conditions at different levels have different effects on the seeds storage: The storage temperature of Hevea brasiliensis seeds is controlled at 22℃, it has the best effect on extending the seeds longevity, and meet the pratical requirement.

初步研究发现，不同水平的环境因子对种子贮藏的影响作用不同：橡胶树种子的贮藏温度为22℃时，对于减缓种子代谢，延长种子寿命效果最佳。

In this study, the aged watermelon seeds were selected as material, soaked by different concentrations of salicylic acid, calcium nitrate and gibberellic acid (GA3), to study the effects on germination rate, related physiological and biochemical indexes of aged watermelon seeds. The results show that the activity of aged watermelon seeds was obviously increased after soaking, and the best treatment to promote germination was Ca(NO3)210mmol/L. Besides, conductivity and soluble sugar content of seeds lixivium, and MDA content of seeds were decreased obviously after treated by SA, Ca(NO3)2 and GA3, and SA treatment had the best obvious effects.

本试验以自然老化的西瓜种为试材，采用不同浓度的水杨酸、硝酸钙、赤霉素预浸种处理，研究其对老化西瓜种子萌发及相关生理生化指标的影响，结果表明：不同处理均可显著提高老化西瓜种子活力，以10mmol/L的Ca(NO3)2处理促进萌发的效果最为明显；不同处理均能明显降低种子浸出液电导率、可溶性糖含量及种子中丙二醛含量，以水杨酸的各处理效果最好。
