1、葡萄品種果實性狀比較摘要:為了解決遵義市葡萄生產(chǎn)上品種單一問題,并為篩選優(yōu)良葡萄品種提供基本數(shù)據(jù),試驗以葡萄品種維多利亞、奧古斯特、紅富士、京亞為材料,采用田間試驗結(jié)合室內(nèi)測定的方法,對葡萄的果實性狀進(jìn)行比較研究。結(jié)果表明,供試葡萄品種的平均單果重、最大穗重存在顯著的差異,果形指數(shù)、平均穗重在歐亞種內(nèi)、歐美種內(nèi)相互無差異,但2個種之間存在顯著的差異;在可滴定酸含量上,2個歐美種品種顯著高于2個歐亞種品種;在可溶性固形物含量、維生素c含量、總糖含量方面,4個品種之間存在一定的差異。相關(guān)分析結(jié)果顯示,可滴定酸含量與可溶
2、性固形物含量、維生素c含量之間存在顯著的正相關(guān)性;最大穗重與平均單果重、平均穗重之間存在極顯著的正相關(guān)性,果形指數(shù)與平均穗重、平均單果重之間存在顯著的負(fù)相關(guān)性。綜合比較而言,4個葡萄品種在遵義市可以正常開花結(jié)果,能適應(yīng)當(dāng)?shù)氐淖匀画h(huán)境。在避雨栽培方式下,4個品種果實的性狀雖然存在一定的差異,但品質(zhì)都在中上水平,其中歐亞種品種在遵義市的表現(xiàn)要優(yōu)于歐美種品種。關(guān)鍵詞:葡萄;品種;果實性狀;比較;遵義市abstract:tosolvetheproblemofsingle-varietyofgrapeproductionin
