2、析表明,B2F煙葉物理特性在不同品種間差異較C3F更突出,其中以填充值和厚度最為明顯。紅大形態(tài)物理指標(biāo)與云煙87存在較大差異,其質(zhì)量物理特性指標(biāo)與NC297差異顯著;NC297具有較高的機(jī)械強(qiáng)度特性;K326的物理特性同其他品種均較為接近。遺傳基礎(chǔ)狹窄使得不同品種烤煙初烤煙葉物理特性趨于一致,滇中煙區(qū)紅大品種特色較突出關(guān)鍵詞:初烤煙葉;品種差異性;物理特性;機(jī)械強(qiáng)度中圖分類號(hào):$572文獻(xiàn)標(biāo)志碼:A文章編號(hào):1004—3268(2014)04—0043—05StudyonDifferencesofPhysicalPropertiesforFlue——curedTobaccoVarietie
