拘杞子 植物體 成分의 品種 및 地域間 差異

Differences of plant components according to the variety and growing area in boxthorn(lycium chinense MILL)

This experiment was conducted to investigate the inorganic matter of leaf, Betain content of root organic matter of fruit and fruit extracts according to the various growing stage. Also, there were the studies on the relation between various fertilizer and its components and obtained the basic data for breeding good high yielding varieties. Varieties used in this experiment were 29 native varieties collected in Korea and oversea and 9 mutant species and planted at Daejeon, Chungnam in 1986. The inorganic matter of leaf and organic matter obsorption of fruit, N and Protein, P₂O₅ and Fat, and K₂O and Carbohydrate significant positive correlation. The releation between fat content and fruit extracts showed significant positive correlation. And there was significant negative correlation between carbohydrate, and protein content and extracts. The content of extracts and fruit yield of Japanese-2 variety was the highest of all and Lycii cortex yield and Betain content of variety treated with Colchicine 0.1% was the highest of all. And than, these varieties could be promising variety to use for breeding high yielding variety.
