Abstract:

Objective This study analyzed different grapevine rootstocks storage and mineral nutrition content in juvenile branch and aimed to provide data for selection and usage of rootstocks. Method Nineteen grapevine rootstocks were collected by fruit research institute, Chinese academy of agricultural sciences and soluble sugar (SS), starch, free amino acid (FAA), soluble protein (SP), nitrogen (N), phosphorus (P), potassium (K), and magnesium (Mg) content were measured and analyzed in juvenile branch and clustering analysis was used to study similarity of different cultivars. Result SS was the main component of storage nutrient in all rootstocks ranging from 44 to 93mg/g, and the difference was significant between treatments. FAA content was fluctuated from 0.8 to 3.5mg/g, meanwhile, SP content had little change. K and P content were significant higher than N and Mg content in branch. K and Mg contents had significant difference between different cultivars, however, the amplitude of variation of nitrogen and P content were smaller. nineteen grapevine rootstocks were subjected cluster analysis and divided to seven class groups, in which 140R was self-contained and SS and starch content was equal, as well as, FAA content was highest but N and P were lower; the class group consisting of 101-14, 420A, and kangzhen No 1 had higher SS, SP, and N content; 34EM, 225Ru, 5BB and 1103P had higher absorption efficiency of K, Mg and P. Conclusion SS was the main component of storage nutrient in grape branch, and K content was highest in mineral nutrient. The storage and mineral nutrient had significant difference among rootstocks, and different features showed from rootstock maybe provide basis for rootstock usage.
