Streptomycin을 利用한 葡萄의 單爲結果 誘起에 關한 硏究
任嚴梁,李載昌 충남대학교 농업과학연구소 1985 農業技術硏究報告 Vol.12 No.1
Several seeded cultivars of Vitis labruscana showing various responses to GA - induced seedlessness were tested to study the effects of streptomycin sulfate on induction of parthenocarpy. The results were summarized as follows. 1. Prebloom dipping of streptomycin sulfate at 200 ppm induced 90∼100% parthenocarpy in 'Schuyler', 'Delaware', 'Ohira-Dela.' and 'Tanored' cultivars and also stimulated maturity but did not show any toxic effects. 2. In most cultivars, the addition of 25 ppm GA to streptomycin tended to increase berry setting and induction of parthenocarpy. 3. Dipping of streptomycin alone in 'Campbell Early' severely induced berry abscission but the addition of calcium acetate or BA to streptomycin slightly increased setting of berries. 4. In 'Kyoho' and 'Pione' cultivars, streptomycin successfully induced parthenocarpy. Berry setting by streptomycin treatment was variable according to environmental conditions. 5. In 'Campbell Early' and 'Tanored' cultivars, streptomycin severely reduced viability of pollen.
