摘要
酿酒葡萄的成熟进程以及风味物质的积累,受到成熟期日照、气温和降雨等气候因素的影响。2014年葡萄成熟季陕西杨凌地区出现长时间持续性降雨,为调查降雨对不同酿酒葡萄品种的影响差异提供了契机。该试验于2013年和2014年对比了杨凌地区2个酿酒葡萄品种(系)成熟度进程和感病情况,分析了不同品种(系)的成熟度指标的变化规律和其对降雨的响应差异。同时结合当地气候特点,研究了酿酒葡萄优选品系"LHN55"在杨凌地区的栽培适应性。结果表明:降水量增加均会阻碍"赤霞珠"和"LHN55"的成熟进程,并加重白腐病侵染面积和感病程度,但优选品系"LHN55"较"赤霞珠"在杨凌地区有更强的抗病性和适应性。
The maturity and flavor substances of winegrapes are affected by climate factors such as sunshine,temperature and rainfall.In 2014,there was a long continuous rainfall in Yangling,which providing an opportunity to investigate the rainfall＇s influence to the maturity of different varieties.The study respectively compared the maturity process and disease situation of‘LHN55＇and ‘Cabernet Sauvignon＇in consecutive two years（2013and 2014）.Meanwhile we analyzed maturity process of different varieties/clones in condition of rainfall to reveal the adaptability of winegrape clone‘LHN55＇.The results showed that the increased rainfall hindered the maturity process of both‘Cabernet Sauvignon＇and‘LHN55＇,and exacerbated the infection of white rot simultaneously.However,‘LHN55＇had stronger disease resistance and better adaptability compared with‘Cabernet Sauvignon＇in Yangling.
