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We studied many methods to improve the tcp / ip in wireless environment, such as tcp / ip initial slow start algorithm, initial window and retransmission time out ( rto ) estimate. finally, we consider the round - trip time ( rtt ) with the physical layer and the transfer layer combined together. physical layer using rtt related to the channel state and transfer layer using the constant rtt, the interference between the two layers can be eliminated, and so the effectiveness of the wireless data link can be enhanced
研究了tcp ip的慢速啟動演算法、初始窗口、重傳超時估計以及改善無線tcp ip性能的各種方法,提出了一種把物理層鏈路和傳輸層相結合處理往返時間( rtt )的方法:物理層鏈路採用與通道相關的動態rtt ,傳輸層採用常數rtt ,消除了兩層rtt之間的相互干擾,從而提高了無線鏈路的利用率。
