摘要:
 Turpan is one of the major high-quality grape production bases in the world for years because its climate is so special (hot, dry, and windy). The grape market needs the varieties with high yield, quality, and environmental adaptability. ‘Xinyu’ is a new variety bred by crossing selection of E42-6 (a self-pollinated inbred of Vitis vinifera cv. ‘Red Globe’) as female and Vitis vinifera cv. ‘Rizamat’ as male parents and registered in the Crop Varieties Registered Commission of Xinjiang Uygur Autonomous Region in 2005. In this study, we determined the impacts of environmental factors on its photosynthesis. The results showed the climate in Turpan was characterized by long-time intensive sunshine, high temperature and relatively low humidity. The peak value of photosynthetic available radiation (PARi) was 1 454 μmol·m-2·s-1, and the minimum and average values were 111 μmol·m-2·s-1and 938.889 6 μmol·m-2·s-1, respectively. Air temperature and sunlight intensity reached the highest values during 1 p.m. to 4 p.m. Net photosynthetic rate (Pn) of Xinyu increased stably before 11 a.m. and there was a midday depression during 11 a.m. to 2 p.m. The minimum value of Pn appeared at noon (2.77 μmol·m-2·s-1). It was concluded that as a new grape cultivar, “Xinyu” could withstand extreme climate conditions in Turpan.
Abstract:
 新疆吐鲁番地区多年来作为世界上优质葡萄的主产地之一,气候条件极其特殊(高温、干燥、多风)。高产、优质、环境适应性强的葡萄新品种一直是市场的需求方向。“新郁”是由E42-6(“红地球”实生优系)为母本,“里扎马特”为父本杂交育成的新品种,于2005年在新疆维吾尔自治区农作物品种登记委员会登记。研究测定了环境因子对葡萄品种“新郁”光合效应的影响。结果表明,吐鲁番地区强光照持续时间长,高温低湿;光合有效辐射(PARi)最高为1 454 μmol·m-2·s-1,谷值为111 μmol·m-2·s-1,平均为938.889 6 μmol·m-2·s-1;大气温度和光照强度在13:00-16:00稳定增长至最高值,净光合速率(Pn)在11:00之前保持稳定增长,在11:00-14:00有“午休”现象,在正午时达最低值,为2.77 μmol·m-2·s-1。可见,葡萄新品种“新郁”在新疆的极端天气下生长适应性良好。
