摘    要:采用直角双曲线模型、非直角双曲线模型、直角双曲线修正模型和指数模型4种光响应模型分别拟合夏黑/贝达、夏黑/1103P、夏黑/101-14、夏黑/3309C、夏黑/140Ru、夏黑/5C、夏黑/5BB、夏黑/420A、夏黑/SO4、夏黑/抗砧1号、夏黑/华葡1号11种砧穗组合的光响应曲线,通过拟合程度、光补偿点、光饱和点、初始量子效率、最大净光合速率、暗呼吸速率等6个参数分析比较其拟合效果.结果表明: 4种模型拟合系数都在0.98以上,在光补偿点上,4种模型拟合效果相差不大,但直角双曲线修正模型在光饱和点、初始量子效率、最大净光合速率和暗呼吸速率方面拟合程度最好,运用赤池信息量准则计算,直角双曲线修正模型赤池信息量准则(AIC)值也最小,因此,直角双曲线修正模型为最佳拟合模型.通过聚类分析发现,夏黑/SO4、夏黑/420A两砧穗组合的表观量子效率高、光补偿点低、暗呼吸速率低,说明两者对弱光的利用效率高,耐弱光能力强,呼吸消耗少.通过Topsis (Technique for Order Prefe-rence by Similarity to an Ideal Solution)方法综合排名发现,夏黑/SO4、夏黑/420A组合耐弱光能力分别为第1、2名,与聚类分析结果一致.因此,夏黑以SO4或420A作为砧木的耐弱光能力最突出,更适合设施栽培.

关 键 词:夏黑  砧穗组合  光响应模型  耐弱光能力

Abstract:The photo response curves of 11 rootstock-scion combinations including summer black/Beta, summer black/1103P, summer black/101-14, summer black/3309C, summer black/140Ru, summer black/5C, summer black/5BB, summer black/420A, summer black/SO4, summer black/Kangzhen No.1, summer black/Huapu No.1 were fitted by rectangular hyperbola mo-del, non-rectangular hyperbola model, modified rectangular hyperbola model and exponential model respectively, and the differences of imitative effects were analyzed by determination coefficiency, light compensation point, light saturation point, initial quantum efficiency, maximum photosynthetic rate and dark respiration rate. The result showed that the fit coefficients of all four models were above 0.98, and there was no obvious difference on the fitted values of light compensation point among the four models. The modified rectangular hyperbola model fitted best on light saturation point, apparent quantum yield, maximum photosynthetic rate and dark respiration rate, and had the minimum AIC value based on the akaike information criterion, therefore, the modified rectangular hyperbola model was the best one. The clustering analysis indicated that summer black/SO4 and summer black/420A combinations had low light compensation point, high apparent quantum yield and low dark respiration rate among 11 rootstock-scion combinations, suggesting that these two combinations could use weak light more efficiently due to their less respiratory consumption and higher weak light tolerance. The Topsis comparison method ranked summer black/SO4 and summer black/420A combinations as No. 1 and No. 2 respectively in weak light tolerance ability, which was consistent with cluster analysis. Consequently, summer black has the highest weak light tolerance in case grafted on 420A or SO4, which could be the most suitable rootstock-scion combinations for protected cultivation.
Keywords:summer black grape  rootstock-scion combination  photo-response model  weak light tolerance ability.
