在人工喷雾下,油橄榄栽培品种嫩枝扦插发根能力的试验在西班牙,用β—吲哚丁酸激素处理可促进油橄榄嫩枝的发根能力。大量的油橄榄栽培品种可用2500ppm—5000ppm 吲哚丁酸而提高繁殖力。那些原来处理不当的插条,再用吲哚丁酸处理也获得效应,而且发了根的插条数量随着吲哚丁酸浓度的增加而增加。用吲哚丁酸处理前,在插条的基部割一、 Tests on rooting ability of shoots of olive cultivars under artificial spraying In Spain, treatment with beta-indole butyric hormone promotes the rooting ability of olive shoots. A large number of olive cultivars can use 2500ppm-5000ppm indole butyric acid to improve fertility. Those with improperly handled cuttings and then with indole butyric acid also had an effect, and the number of cuttings with roots increased as the indole butyric acid concentration increased. Before treatment with indole butyric acid, cut one at the base of the cuttings,
