Abstract

The objective was to evaluate plant growth regulators and ethylene inhibitors on the development and leaf abscission of Schinopsis brasiliensis Engl. Zeatin (ZEA) was evaluated in concentrations combined with concentrations of indolacetic acid (IAA), naphthalene acetic acid (NAA) and indolbutyric acid (IBA). ZEA and 6-benzylamino purine (BAP) were evaluated in concentrations plus a control. Ethylene inhibitors, silver nitrate and cobalt chloride were evaluated in four concentrations. The addition of 0.2 μL-1 of NAA to 0.4 μL-1 of ZEA promotes a greater number of baraúna sprouts. At concentrations of 5 and 10 μM, cobalt chloride is more efficient than silver nitrate for reducing leaf abscission in baraúna. IAA is the most suitable auxin to be associated with ZEA for higher shoot length and number of buds. Silver nitrate from a concentration of 20 μM completely avoids leaf abscission while cobalt chloride has a maximum reduction in abscission at a concentration of 40 μM.

巴西小檗的增殖、形态发生和叶面脱落。在体外

目的是评价植物生长调节剂和乙烯抑制剂对巴西小茴香发育和叶片脱落的影响。玉米素(ZEA)与吲哚乙酸(IAA)、萘乙酸(NAA)和吲哚丁酸(IBA)浓度联合测定。测定ZEA和6-苄基氨基嘌呤(BAP)的浓度和对照。对四种浓度的乙烯抑制剂、硝酸银和氯化钴进行了评价。NAA添加0.2 μL-1, ZEA添加0.4 μL-1，可促进baraúna芽的数量增加。在5 μM和10 μM浓度下，氯化钴比硝酸银更有效地减少baraúna叶片脱落。IAA是最适合与ZEA配用的生长素，可以获得较高的茎长和芽数。20 μM浓度的硝酸银完全避免叶片脱落，而40 μM浓度的氯化钴最大程度地减少叶片脱落。

期刊介绍： The Boletín Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas (BLACPMA), [Latin American and Caribbean Bulletin of Medicinal and Aromatic Plants]; currently edited by the publishing house MS-Editions, is a bi-monthly international publication that publishes original peerreviewed research in the field of medicinal and aromatic plants, with nearly 20 years of experience. BLACPMA is a scientific journal that publishes two types of articles: Reviews (only in English) and Original Articles (Spanish or English), its main lines of action being agronomy, anthropology and ethnobotany, industrial applications, botany, quality and standardization, ecology and biodiversity, pharmacology, phytochemistry, pharmacognosy, regulatory and legislative aspects. While all areas of medicinal plants are welcome and the experimental approaches used can be broad and interdisciplinary; other areas of research that are not mentioned depend on the Editorial Committee for their acceptance.
