摘要

本试验的目的是测定生长素和细胞分裂素对江铃草营养繁殖的影响。用9种不同激素水平处理插条；对照（不含激素），将插条末端浸入50ppm、100ppm、150ppm和200ppm的生长素（吲哚3-乙酸）溶液中，并将插条端部浸入50ppm或100ppm或150ppm或200ppm的细胞分裂素（苄基氨基嘌呤）溶液中15分钟，然后在塑料盘中种植。21天后，将插条用塑料袋移植到温室的土壤中。在移植后50天收获牧草以确定产量和质量。结果表明，激素对株高、叶片数、一级分枝数、三级分枝数以及产量和营养价值均有影响。结果表明，植物激素可以作为饲料用于黑曲霉的营养繁殖。

Evaluation of auxin and cytokinin use for vegetative propagation of Asystasia gangetica for forage production

The aim of the experiment was to determine the effects of auxin and cytokinin application on vegetative propagation of Asystasia gangetica for forage production. Stem cuttings were treated with 9 different hormone levels; control (without hormone), immersion of ends of cuttings in 50, 100, 150, and 200 ppm solutions of auxin (indole 3-acetic acid) and immersion of ends of cuttings in 50, 100, 150, and 200 ppm solutions of cytokinin (benzyl amino purine) for 15 minutes, followed by planting in plastic trays. After 21 days, cuttings were transplanted into soil in polybags in the greenhouse. Forage was harvested 50 days after transplanting to determine yield and quality. The results showed that hormones affected plant height, leaf number, primary branch number, tertiary branch number, yield and nutritional value. It can be concluded that plant hormones can be used for vegetative propagation of A. gangetica as forage.

期刊介绍： The Journal publishes, in English or Spanish, Research Papers and Short Communications on research and development, as well as contributions from practitioners (Farmer Contributions) and Review Articles, related to pastures and forages in the tropics and subtropics. There is no regional focus; the information published should be of interest to a wide readership, encomprising researchers, academics, students, technicians, development workers and farmers. In general, the focus of the Journal is more on sown (''improved'') pastures and forages than on rangeland-specific aspects of natural grasslands, but exceptions are possible (e.g. when a submission is relevant for a particularly broad readership in the pasture and forage science community). The Journal will also consider the occasional publication of associated, but closely related, research in the form of an additional scientific communication platform [e.g. a re-make of the former Genetic Resources Communication series of the former Division of Tropical Crops and Pastures of the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia]. Areas of particular interest to the Journal are: Forage Genetic Resources and Livestock Production[...] Environmental Functions of Forages[...] Socio-economic Aspects[...] Topics within the aforementioned areas may include: Diversity evaluation; Agronomy; Establishment (including fertilization); Management and utilization; Animal production; Nutritive value; Biotic stresses (pests and diseases, weeds); Abiotic stresses (soil fertility, water, temperature); Genetics and breeding; Biogeography and germplasm collections; Seed production; Ecology; Physiology; Rhizobiology (including BNF, BNI, mycorrhizae); Forage conservation; Economics; Multilocational experimentation; Modelling.
