研究了不同类型甜菜品科叶部光合性状与产质量的关系，结果表明：在不同生育时期RuBP数化酶活性在品种之间存在显著差异，可将其作为前期和糖分积累期选育高糖型品种的生理指标，并可在块根增长期作为选育丰产型品种的生理指标；在苗期与块根增长期，光合速率与块根产量呈极显著正相关，在整个生育期间单株叶面积均与产量呈正相关，因此可将单株叶面积、光合速率和分配率一并作为丰产型品种的选育指标。 The relationship between photosynthetic characteristics and yield and quality of different types of sugar beet leaves was studied. The results showed that there were significant differences in the activity of RuBP between different varieties at different growth stages, which could be used as the prophase and sugar accumulation period The physiological indexes of the varieties and the growth of tuberous root can be used as the physiological indices for the breeding of high yielding varieties. At seedling stage and tuberous growth stage, the photosynthetic rate and tuber yield were significantly and positively correlated. During the whole growth period, And yield were positively correlated, so the leaf area per plant, photosynthetic rate and distribution rate can be used as a breeding index for high yielding varieties.
