| 摘 要： | 褐藻酸寡糖对草莓的形态指标和光合特性有显著的促进作用，本试验的目的是筛选出能促进草莓生长、提高果实品质最佳的褐藻酸寡糖。以“红颜”草莓品种为试验材料，采用不同聚合度的褐藻酸寡糖对草莓的形态特征、叶片光合特性指标和品质影响进行研究。结果表明，褐藻酸寡糖能提高草莓叶片SPAD值，能促进叶片的光合特性，提高草莓根系活力。褐藻酸寡糖1号（聚合度为50）处理的净光合速率、根系特征和草莓品质最好。

The Effect of Alginate oligosaccharides on Photosynthetic Characteristics and plant morphological characteristics of strawberry leaces |
| |
| Abstract: | Alginate oligosaccharides significantly promoted the morphological and photosynthetic characteristics of strawberry. This experiment aimed to screen alginate oligosaccharides, which can promote Strawberry Growth and improve fruit quality. The effects of different alginate oligosaccharides on morphological characteristics, photosy nthetic characteristics and quality of strawberry were studied. The results showed that alginate oligosaccharide could increase SPAD value of strawberry leaves, promote photosynthetic characteristics of leaves, and improve root activity of strawberry. T1 ,with 50 degree of polymerization, was best because it had the optimal net photosynthetic rate, root characteristics and strawberry quality. |
