Abstract

Cutting is an alternative kiwifruit propagation, to obtain rootstocks or to directly root its. As a clonal propagation method, there is no loss of desirable agronomic characteristics. This study was carried out to evaluate the rooting of softwood cuttings of kiwifruit ‘Bruno’, ‘Elmwood’ and ‘Matua’ (Actinidia deliciosa) and ‘MG06’ (Actinidia chinensis) submitted to indolebutyric acid (IBA) treatment. The cuttings were immersed, at their base, in concentrations 0, 1000, 2000, 4000, 6000 and 8000 mgL-1 of IBA. After 90 days, the following variables were evaluate: percentage of rooted cuttings, callus and leaf retention per cutting; average length of the three largest roots; average number of roots and root dry matter mass. The rooting of ‘MG06’ is higher than ‘Elmwood’ and ‘Matua’, not differing from ‘Bruno’. ‘Matua’ presented the lowest rooting. The AIB increases the rooting percentage, and with an estimated concentration of 4,640 mgL-1, it, can obtain 48.9% of rooted cuttings.
吲哚丁酸处理4个kiwizeiros基因型草本扦插生根的研究
扦插是猕猴桃繁殖的一种替代方法,可获得砧木或直接根茎。作为无性系繁殖方法,没有损失理想的农艺性状。以猕猴桃‘Bruno’、‘Elmwood’、‘Matua’(Actinidia deliciosa)和‘MG06’(Actinidia chinensis)为材料,研究了吲哚丁酸(IBA)处理对猕猴桃扦插生根的影响。在岩屑底部分别浸入浓度为0、1000、2000、4000、6000和8000 mg -1的IBA。90 d后,对扦插生根率、愈伤组织率和叶片保持率进行评价;三个最大根的平均长度;平均根数和根干物质质量。‘MG06’的生根高于‘Elmwood’和‘Matua’,与‘Bruno’相差不大。“Matua”的生根率最低。AIB处理可提高扦插生根率,在4640 mg -1的浓度下,可获得48.9%的扦插生根率。

期刊介绍: The Iheringia, Série Botânica is a publication edited by the Museu de Ciências Naturais, Fundação Zoobotânica do Rio Grande do Sul, since 1958. The name Iheringia is actually a tribute to Hermann von Ihering (a German researcher who became a Brazilian citizen) and his important studies in the Natural Sciences.The journal has the mission of publishing articles, reviews and original scientific notes that cover diverse areas in Botany, and may be written in Portuguese, Spanish and English. The journal is widely available in both international and national scientific community. The issues are published and distributed twice a year to 118 national institutions and 152 international institutions. The distribution is either free of charge or by exchange.
