Juniperus squamata 'Blue Star'%Nutrient-mist%NaHSO_3%Nutrition%Cutting%Rooting
In this study, we investigated the optimal concentration of nutrient-mist and NaHSO_3 for cutting propagation of Juniperus squamata 'Blue Star' , as well as the variation in the contents of chlorophyll in leaves, and solubility carbohydrate,soluble protein and other nutrition in leaves and bases of cuttings during rooting. Cuttings of grade Ⅲ (the lenghth of cutting bases lignified from 0.1 to 0.2 cm) was treated by were improved compared with control experiment, for there were different effects among three grade cuttings. The treatment of grade Ⅲ cuttings also resulted in higher content of soluble sugar and starch of those bases during rooting, especially obviously different for fifteen days, but less effect on the chlorophyll and some nutrition content of cutting leaves.
