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。

Maximumprotein synthesis of high vigor seed appeared at 24 hours after imbibition, that oflow vigor seed not remarkable.

高活力种胚在吸胀24h达到最高值，而低活力种胚吸胀后变化不大。

Choose vigorous and fertile strains for out-crossing. Since inbreeding is part of the strategy for setting a new strain and inbreeding often leads to reduced fertility and vigor, the fertility and vigor of the outcross strain is important.

必须选择具有活力及多产能力的鱼种来做异种杂交所需的鱼种，因为自交也是建立创造新品系鱼种的重要改鱼步骤之一，而且自交过程通常会导致鱼只生产能力及活力的降低。

For measuring of seed vigor , we study seed vigor quantitatively by means of computing specific value of stained and unstained area in plumule

种子活力的人工检浏是通过计算胚芽中染色的面积与未染色的面积的比值来定量的研究种子的活力。

Sex-linkage model reveals that hybrid vigor rate is a complex function related withdominance of gene effects of hybrid,additivity and dominance of the parent genes,and ef-fects of sex-linked genes.Owing to interaction of genes and environment,hybrid vigor ratevaries with seasons.

性连锁模型揭示，杂种优势率是一个与杂交种的显性效应、亲本的加性效应、显性效应、性连锁效应等基因效应有关的复杂函数，由于基因与环境的互作，造成杂种优势率在不同季节表现不一致。

Exgenous ABA could inhibit germinationof high vigor seeds at low concentration(5ppm).The germinative power,percentage germinationand vigor index were significantly reduced.

外源ABA对高活力种子萌发有显著抑制作用，在低浓度（5ppm）时，种子发芽势、发芽率及活力指数都显著下降；当浓度达40ppm时，则完全抑制种子萌发。

Results show that, by uv-vis spectra, fluorescence spectra and Fourier infrared spectra transform all successfully gained water-soluble CdTe quantum dots. With the increase of water-soluble CdTe quantum dot concentration increasing, Achyranthes Bidentata root length and the seed vigor reduced ordinally, but its germination changed no obviously, suggested the space mutagenesis treatment can improve Achyranthes Bidentata seed vigor.

结果表明，紫外－可见光谱、荧光光谱和傅立叶红外变换光谱图均说明已成功制备水溶性CdTe量子点；随水溶性CdTe量子点浓度增大，牛膝的根长和种子活力依次降低，但其对发芽势影响的规律不明显，经空间诱变处理能提高牛膝种子活力。

The result shows: in 0~360 kg/hm^2 fertilizer can improve the plant height, dry matter accumulation of maize, nitrogen accumulation, root vigor, leaf nitrate reeducates activity, chlorophyll content and yield, meanwhile the leaves' nitrate reeducates activity, dry matter accumulation and the final output of wheat, root activity and other indicators were significantly correlated; Cultivating under the same conditions and dropping the fertilizer amount from 360 kg/hm^2 to 315 kg/hm^2, the dry matter accumulation will be increased, the roots vigor and leaf nitrate reeducates activity will be strengthened, but the yield are not obviously different in the same treatment.

结果表明：在0~360kg/hm^2的施肥范围内，肥料能显著增加玉米植株的株高、干物质积累盆、叶绿素含量和籽粒产量，提高根系活力、叶片硝酸还原酶活性；同时硝酸还原酶活性、干物质积累量、根系活力和叶绿素含量等指标与玉米最终产量呈显著正相关；在相同的栽培条件下，将施肥量从360kg/hm^2降至315kg/hm^2，植株的于物质积累量增加、根系活力、叶片硝酸还原酶活性增强，但处理间籽粒产量无显著差异。
