  • mean : vt 1 意，有…的意思，意思是…。2 意指，用…意思說；意味著，就是。3 （用語言、繪畫等）表示意思，表示...
  • and : n. 1. 附加條件。2. 〈常 pl. 〉附加細節。
  • variance : n. 1. 變化，變動，變更；變度，變量；【統計】（平）方（偏）差。2. （意見等的）相異；不和，沖突，爭論。3. 【法律】訴狀和供詞的不符。
  1. 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
  2. Mean, variance, standard deviation, coefficient of variation of fourteen vital morphological characters indicated that great diversity existed either among species or among populations, with cv ranging from 28. 89 - 122. 36 % ( except dtm, which has a cv of 4. 72 % ). correlation analysis indicated that il showed a significant positive correlations with pfk ll and lw ( p < 0. 05 ), but a negative correlation with nm ( p < 0. 05 ). there were also strong positive correlations between each other of ll, lw, la and sw

    相關分析表明，節間長度與株高、葉長、葉寬呈顯著正相關，而與主莖節數呈顯著負相關；葉長、葉寬、葉面積、千粒重四個性狀相互之間存在極顯著正相關；干重和單株種子產量兩者之間存在極顯著正相關；出苗率與千粒重之間存在顯著負相關；生長習性與分枝數之間存在顯著正相關；全生育天數與生長習性之間存在顯著負相關。
