簡(jiǎn)介：摘要摘要以全展后的兩優(yōu)培九劍葉為研究對(duì)象，同時(shí)期的父本9311和母本培矮64S為對(duì)照，對(duì)兩優(yōu)培九、父本9311和母本培矮64S在衰老進(jìn)程中不同時(shí)期劍葉的光能轉(zhuǎn)化功能特性，膜脂脂肪酸成分變化及葉片超微結(jié)構(gòu)變化進(jìn)行了研究，揭示了劍葉整個(gè)衰老過(guò)程中細(xì)胞水平上的一些變化的規(guī)律。結(jié)果顯示一、三材料凈光合速率呈前期上升中后期下降。呼吸速率的變化為前期較低，中期稍有上升，但后期差異較大。兩優(yōu)培九在光能轉(zhuǎn)化上有一定的超親優(yōu)勢(shì)。兩優(yōu)培九的PSI、PSII電子傳遞活性在整個(gè)劍葉生長(zhǎng)期間都是最高的，其次是父本，母本最低。從遺傳角度看，兩優(yōu)培九在光能轉(zhuǎn)化方面，更傾向于父本，而受母本影響則相對(duì)較小。二、膜脂脂肪酸不飽和指數(shù)是一個(gè)比較有意義的指標(biāo)。兩優(yōu)培九、父本9311和母本培矮64S不同部位脂肪酸不飽和指數(shù)呈起始和最后略低，中間稍高的趨勢(shì)。意味著在植物膜脂成分中，不飽和脂肪酸的含量對(duì)維持膜的正常生理功能有著重要的作用，飽和脂肪酸含量的提高往往不利于植物的生長(zhǎng)發(fā)育，這可能與膜的流動(dòng)性能有關(guān)。整個(gè)劍葉生長(zhǎng)期間，脂肪酸中140、160和18L的含量變化基本呈上升趨勢(shì)；而161、182和183則是呈現(xiàn)下降趨勢(shì)。膜脂脂肪酸不飽和指數(shù)的下降主要是由于上三種脂肪酸下降所致。兩優(yōu)培九三數(shù)據(jù)的變化比較平穩(wěn)。結(jié)構(gòu)上的穩(wěn)定意味著可以保持功能上的穩(wěn)定，兩優(yōu)培九可以在葉片水平上長(zhǎng)時(shí)間的保持的凈光合速率及呼吸速率的穩(wěn)定與此有相當(dāng)大的關(guān)系。這為兩優(yōu)培九長(zhǎng)時(shí)間的積累同化產(chǎn)物，提高最終產(chǎn)量提供了結(jié)構(gòu)上的保證。兩優(yōu)培九在膜臘脂肪酸成分上與雙親的遺傳關(guān)系與母本更為相似。三、細(xì)胞及葉綠體結(jié)構(gòu)觀測(cè)表明劍葉生長(zhǎng)早期，細(xì)胞內(nèi)葉綠體多呈狹長(zhǎng)形或橢圓形，數(shù)目較多。細(xì)胞核體積較小，核膜核孔清晰，核內(nèi)核質(zhì)濃密而均勻。隨著生長(zhǎng)進(jìn)程的加深，葉綠體體積出現(xiàn)增大，內(nèi)部類囊體膜基粒片層部分模糊不清，淀粉粒變大，同時(shí)出現(xiàn)嗜鋨滴。但此時(shí)細(xì)胞核與線粒體沒有出現(xiàn)較大的變化。在劍葉衰老后期葉綠體已經(jīng)膨大，基粒片層松散紊亂，嗜鋨滴數(shù)目增多，體積增大，線粒體減少，內(nèi)部出現(xiàn)空泡化；細(xì)胞核的體積增大，核膜出現(xiàn)消融，核孔擴(kuò)大，核質(zhì)疏松，并向外散逸。兩優(yōu)培九在光合能力上有～定的結(jié)構(gòu)優(yōu)勢(shì)一、細(xì)胞內(nèi)葉綠體數(shù)目較多，基粒
