簡(jiǎn)介:新舊玉米雜交種在高種植密度條件下的生長(zhǎng)表現(xiàn)新舊玉米雜交種在高種植密度條件下的生長(zhǎng)表現(xiàn)摘要摘要抗逆性優(yōu)良的玉米雜交種的遺傳改良是通過(guò)增加種植玉米群體數(shù)量來(lái)為增產(chǎn)做出貢獻(xiàn)的。這項(xiàng)研究對(duì)尼日利亞大草原上不同的年代的玉米雜交種在高種植密度下的反應(yīng)進(jìn)行了評(píng)估。分別在2002年和2003年,對(duì)位于北部幾內(nèi)亞熱帶草原地帶的尼日利亞扎里亞薩馬魯?shù)霓r(nóng)業(yè)研究所試驗(yàn)站進(jìn)行實(shí)地調(diào)查。六個(gè)品種,兩個(gè)來(lái)自于20世紀(jì)80年代,兩個(gè)來(lái)自于20世紀(jì)90年代,兩個(gè)來(lái)自于21世紀(jì)三個(gè)種植密度,采用裂區(qū)設(shè)計(jì),3次重復(fù)。種植密度(53,333,66,666和79999株/公頃)為主區(qū),6個(gè)雜交品種為副區(qū)。種植密度超過(guò)53,333株/公頃的雜交種減產(chǎn),這可能是由于試驗(yàn)選擇的雜交種是在低種植密度下進(jìn)行的,因此對(duì)種植密度壓力沒(méi)有耐性。這也可能是由于試驗(yàn)區(qū)低的增產(chǎn)潛力,它不允許在高種植密度下增產(chǎn)。測(cè)試雜種之間存在顯著性差異。在所有密度條件下,21世紀(jì)的雜交種的產(chǎn)量高于20世紀(jì)80年代和20世紀(jì)90年代的雜交種。為了在高種植密度下提高玉米的產(chǎn)量,我們建議在在高種植密度下選擇雜交種。關(guān)鍵詞關(guān)鍵詞玉米雜交種;種植密度;玉米產(chǎn)量。光合作用是決定作物產(chǎn)量的最重要的因素之一,因?yàn)榇笥?0的作物干物重直接來(lái)自于光合作用。這意味著,在農(nóng)業(yè)生產(chǎn)中,光合效率直接關(guān)系到最終產(chǎn)量。因此,許多國(guó)家的研究人員已經(jīng)積極地參與到新的育種方法的研究中,目的是改善作物的光合能力4,5,并且通過(guò)我們長(zhǎng)期在不同發(fā)育階段采取多種措施以提高作物生產(chǎn)潛力的研究,高光效育種已經(jīng)被視為重要的方法之一。在過(guò)去的二十年里,通過(guò)植物生理學(xué)家和基因?qū)W家的密切科學(xué)合作,中國(guó)研究人員已經(jīng)采取許多不同手段,廣泛地研究了個(gè)別作物增加產(chǎn)量的潛力,并且已經(jīng)取得了明顯進(jìn)展。這篇文章是對(duì)我們以前在玉米高光效育種研究以及其他研究者的相關(guān)工作的簡(jiǎn)短回顧。不同的光合參數(shù),例如光截獲能力、光能轉(zhuǎn)換效率、碳同化作用和光合特性的遺傳等等,都有待討論。引言引言玉米的糧食產(chǎn)量受植物種群密度的影響比其它禾本科的植物明顯,這是因?yàn)橛衩椎姆痔Y能力低,且為雌雄同株的植物,存在一個(gè)相對(duì)短的花期(SANGOI等,2002)。理想的植物種群取決于幾個(gè)因素,例如,水份的供應(yīng),土壤肥力,成熟期和行距(ARGENTA等人,2001年)。低的種植密度能延遲冠層的郁閉和減少光截獲,導(dǎo)致高糧食生產(chǎn)低糧食單產(chǎn)(安德拉德等人,1999)。另一方面,較高的種植密度,提高同化物、水分和養(yǎng)分(EDMEADES等,2000)的競(jìng)爭(zhēng)。高種植密度也促進(jìn)不結(jié)實(shí)和增加開花吐絲間隔(ASI)(SANGOI等人,2001),從而降低了玉米主要產(chǎn)量構(gòu)成單位面積的籽粒產(chǎn)量。地塊,需經(jīng)過(guò)兩個(gè)星期整理。試驗(yàn)前茬的作物是大豆(大豆(屬)美林),其次是2年休耕的地塊。在種植時(shí),N、P和K肥料40KG/HA。在種植五周后施用其他形式的氮肥,以尿素為主,60公斤/公頃(WAP)??刂齐s草,整地前兩個(gè)星期使用草甘膦(N(膦酰基甲基)甘氨酸),七個(gè)星期后用百草枯(11DIMETHLY4,4聯(lián)吡啶氯化)。從播種到50%的花粉棚(開花期)和50%的絲擠出(吐絲期)的日期是由30株決定的,它們位于每個(gè)小區(qū)中間兩行。開花吐絲間隔(ASI)指開花期和吐絲期之間的日期。根倒伏百分?jǐn)?shù)從中央行錄得。糧食產(chǎn)量從每個(gè)小區(qū)的中央行取得,不包含每一行結(jié)束植株。在收獲時(shí)記錄每一個(gè)小區(qū)總的植株數(shù)和穗數(shù)。穗數(shù)/植株數(shù)計(jì)算為植株總的穗數(shù)除以總植株數(shù)。從每小區(qū)收獲的穗先去殼,再使用迪基約翰水分測(cè)定儀(型號(hào)14998,迪基約翰公司,阿拉巴馬州奧本市)進(jìn)行水分百分率測(cè)定。計(jì)算糧食產(chǎn)量時(shí),要將去殼的糧食的水分百分率降至12%。數(shù)據(jù)使用SAS方差分析程序進(jìn)行了方差分析(SAS學(xué)院,1990)。分析了兩年的數(shù)據(jù)除了根倒伏的百分率,其中僅在2003年收集的數(shù)據(jù)SPLITSPLITPLOT模型作為第一要素,種植密度為第二個(gè)因素,雜交種作為第三個(gè)因素。2003年,使用分割的方法對(duì)根倒伏百分率的數(shù)據(jù)進(jìn)行了分析,結(jié)果是“分區(qū)處理間進(jìn)行的LSD在P≤005”。原文出處COMMUNICATIONSINBIOMETRYANDCROPSCIENCEVOL1,NO1,2006,PP41–48
