Analysis of Main Nutritional Components in Flowers and Leaves of 2 Lonicera cuminata Germplasm

The research is mainly aimed at the comparative analysis of the flower bud in different growth steps and in leaves of two kinds of Lonicera cuminata. The result reflects that there are high contents of soluble protein, amino acids contents, soluble sugar contents, Vc, K, Ca and Mg, but little contents of Fe and Mn in the flower bud and leaves of "Cuilei 001" and "Cuilei 003". What's more, the contents of soluble protein, amino acids, soluble sugar and K in flower bud are much higher than those of leaves. However, the contents of Vc, Ca and Mg in leaves are higher than those of flower bud. There are high levels of the nutritional components of flower bud between the stages of Sanqing and Dabai-Erbai and leaves of 10 similar to 45 d. The highest contents of various nutrient elements in flower bud were: soluble protein content 15.51%, amino acids 17.05 mg/g.FW, Vc 32.54 mg/100g.FW, soluble sugar 15.93%, K 15.63 mg.DW, Ca 3.25 mg.DW, and Mg 4.93mg.DW. The highest contents of various nutrient elements in leaves were: soluble protein content 13.50%, amino acids 10.45 mg/g.FW, Vc 52.48 mg/100g.FW, soluble sugar 10.89%, K 13.60 mg.DW, Ca 15.01 mg.DW, and Mg 5.94mg.DW.
