2、表明,光強(qiáng)一致或不一致條件下,茄子葉片中葉綠素a和b含量均以藍(lán)色膜下最高,且顯著高于無色膜處理;葉綠素a/b比值則以無色膜下最大。茄子葉片凈光合速率、干物質(zhì)積累量及根系活力在未調(diào)節(jié)光強(qiáng)時(shí)均以無色膜下最高;調(diào)整光強(qiáng)后則為紅色膜下最高。兩茬試驗(yàn)中,茄子株高均以紫色膜下最高;而莖粗在未調(diào)節(jié)光強(qiáng)時(shí)以無色膜下最高,調(diào)節(jié)光強(qiáng)后則以紅色膜下最高。綜上所述,在光強(qiáng)一致的條件下,紅色膜處理更有利于茄子的生長發(fā)育?!P(guān)鍵詞:有色膜;茄子;生長;光合特性;干物質(zhì)積累中圖分類號(hào):S11+7;$682.2+1文獻(xiàn)標(biāo)識(shí)碼:A文章編號(hào):1000—2324(2013)04—0485—06DⅡ’FERE
