揷木繁植에 의한 땅콩種子增殖

Multiplication of F1 Peanut Plants by Vegetative Propagation

This experiment was carried out to establish the cutting method and to increase the seeds of F₂ populations by cutting from F₁ plant. Cuttings treated with NAA were higher than IAA in rooting ratio, and which in the concentration of 1,000ppm cuttings were rooted highest by 89.8% and sections with 2-bud also higher than 1-bud in rooting. In the cultured clay soil cutting media, cuttings showed better rooting success with vigorous growth than in sand or uncultured soil media. From a F₁ hybrid plant, 4 and 57 rooted cuttings were taken which produced average of 15 and 11 seeds per twice respective cutting at 75 days and 125 days after planting seed stock. Therefore 2 lots of cutting from a plant and seed stock produced 794 seeds totally.
