  4. This study was conducted to examine the interrelationship of 10 seed vigor traits in 12 wheat genotypes through variance, co - variance and path coefficient analysis, to determine broad - sense heritability, and to estimate genetic advance under selection. the genotypes showed significant difference for all traits, except for percentage of normal seedling. genetic correlation between conversion efficiency of seed reserve, electrical conductivity with other traits were not significant, showed that selection for any of them might be possible without hampering any other traits. however path coefficient analysis indicated that conversion efficiency of seed reserve, seed reserve utilization ratio have strong direct effect in affecting seedling weight, and that mean germination time has significantly negatively correlated in affecting gi. moderate to high estimates of broad - sense heritability, genetic coefficient of variation and expected genetic advance were obtained for electrical conductivity, germination index, mean germination time, seed dry weigh, seedling dry weigh, seed reserve depletion ratio indicating the possibility for improving these traits

    本研究利用12個普通小麥品種對10個種子活力性狀的遺傳變異和相關研究，表明除正常幼苗百分率外，其餘種子活力性狀在品種間均存在顯著的差異.種子貯藏物質轉換效率、電導率兩個性狀間及與其它性狀均無顯著的遺傳相關，因此對他們的選擇不會影響到其它性狀.通徑分析表明幼苗干重主要取決于種子貯藏物質轉換效率、種子貯藏物質利用速率;發芽指數主要由平均發芽時間決定.電導率、發芽勢、幼苗干重、種子干重、發芽指數、種子貯藏物質消耗比率6個性狀表現中到高的遺傳力、遺傳變異系數和相對遺傳進展，指明通過遺傳育種手段改良這些性狀是可能的
  5. 81 % and 58. 82 % in those of the control plants respectively. all showed that low - energy ions cause the seed germination vigor to decrease

    由此可見，低能離子注入不僅可以引起擬南芥苗的生長狀態和表型的變異，而且部分變異是可以穩定遺傳的。
  6. In this research, we obtained the results as follows : firstly, the germination vigor of m0, m, and m2 seeds irradiated by the different doses of low - energy n * were compared and analyzed in our experiments. the results showed that the germination and seedling formation rates of the treated seeds and their offspring seeds were lower than that of the control and the rates decreased with the implantation dose intensification. furthermore, the germination and seedling formation rates of the seeds treated with the dose of sox 1015n7cm2 were only 7

    通過本文的研究，主要取得了如下的結果：首先，對不同劑量的低能n ~ +處理的擬南芥的m _ 0代、 m _ 1代和m _ 2代種子的萌發力進行了比較和分析，發現經不同劑量的低能離子處理的擬南芥的當代和後代的種子的發芽率和成苗率都比對照有不同程度的降低，降低關系與劑量成正相關，其中80次劑量處理的當代種子的發芽率和成苗率僅為對照的7 . 81和58 . 82 ，這表明低能離子注入可以引起種子的萌發力的下降。
  7. Influence of harvesting time of perennial ryegrass on germination and vigor of seed

    多年生黑麥草收獲時間對種子發芽特性及其活力的影響
  8. As concentration of salt solution increased, the vigor index, germination index and the length of shoot and radical gradually decreased. the radicle was sensitive to salt stress and had low tolerance. it can be concluded that p. hendersonii has high salt tolerance, h. strobilaceum has low salt tolerance

    隨著鹽溶液濃度的升高，大葉白麻和鹽節木種子的活力指數和發芽指數下降，幼芽和幼根的長度逐漸變短，幼根對鹽分脅迫敏感，忍耐力不強。
  9. The stimulation of the he - ne laser irradiation effect on the vigor was clearer than the growth potential of germination and germination capacity. it indicated that the stimulation effect was expressed in early phase clearly

    激光對uv - b處理后小麥幼苗發芽勢、發芽率的促進作用大於生長勢，說明這種促進作用在萌發早期表現的較為明顯。
