美洲葡萄品种Conquister引种研究

目的]为美洲葡萄品种Conquister的栽培推广提供科学依据。方法]以适应杨凌种植的美洲制汁品种康可和欧亚酿酒品种梅鹿特为对照,对Conquister进行物候期、栽培性状、适应性等的研究。结果]在杨凌气候条件下,Conquister从萌芽至采收需129d,活动积温2768.6℃,为中早熟品种。它生长势强,结果枝百分率高,较丰产,成熟时果香浓郁,有肉囊,果汁浅红,酸甜可口。在杨凌,它的抗性表现极强,生命力旺盛,适应性强,易栽培。结论]该品种的丰产性、浆果品质优于对照品种,其抗病性、适应性与对照品种康可相近。果实香气浓郁,酸甜适口,有肉囊,可发展为优良的制汁品种。

Studies on Introducing America Grape Variety Vitis Labrusca cv. Conquister

Objective] The study aimed to supply scientific basis for the cultivation and popularization of America grape variety Conquister. Method] With America juicing variety Kangke and European and Asian wine variety Meilute that could fit to be planted in Yangling as CK, the research on the phenological period, cultivation traits and adaptability was conducted. Result] Under the climate condition of Yangling, for Conquister, the time from germination to harvest was 129 d, the active accumulated temperature was 2 768.6 ℃, so it was premature variety. Its growth was strong and fruiting branch percentage was high, so it was very high-yield. When the fruits matured, they had concentrated aroma and fruit bursa, the juice was light red and sweet and sour, very delicious. In Yangling, its resistance was extremely strong, growth was prosperous and adaptability was strong, so it was easy to cultivate. Conclusion] The variety's high-yield property and berry quality was superior to CK variety and its disease-resistance and adaptability were similar to CK variety Kangke. The fruit was sweet and sour, with concentrated aroma and fruit bursa. So the variety could be developed to superior juicing variety.
