Abstract

ABSTRACT Rosemary (Rosmarinus officinalis L.) is an important medicinal and aromatic herb, used by various pharmaceutical, food and cosmetics industries. For most species, seed-based multiplication is effective and convenient, but for rosemary, seed germination is a problem due to the mucilaginous seed coat, and sometimes the germination is no more than 10–20% resulting in non-uniform crop establishment. This investigation was carried out to improve seed germination by using low-cost organic seed priming techniques. Eleven pre-sowing seed treatments were tested, based on locally available resources, including: soaking seeds in water (cold and hot), bovine urine (5%, 10%, 15% and 20% concentration), bovine dung slurry, buttermilk, compost tea and Agnihotra ash, and comparing with an untreated control. All the pre-sowing seed treatments increased the percentage of seed germination in rosemary compared with the control, except buttermilk, which had an adverse effect. Among the different treatments, seed germination was significantly increased to 46.7% for seeds treated with bovine dung slurry and to 42.0% for seeds treated with bovine urine5.0%, compared with those in the control where the germination was 9.7%. The bovine dung slurry treatment also recorded uniform and early germination (9 days for initiation and completion at 43 days) resulting in a significantly higher rate of germination (1.4) than the control. The number of leaves, the root length and the seedling vigour were also recorded to be the highest for seeds treated with bovine dung slurry, followed by bovine urine5.0%.
有机播前种子处理对迷迭香种子萌发和生长的影响
迷迭香(Rosmarinus officinalis L.)是一种重要的药用和芳香草本植物,广泛应用于制药、食品和化妆品行业。对于大多数品种来说,种子繁殖是有效和方便的,但对于迷迭香来说,由于粘质种皮,种子发芽是一个问题,有时发芽率不超过10-20%,导致作物建立不均匀。本研究采用低成本的有机催种技术提高种子萌发率。根据当地现有资源,试验了11种播前种子处理,包括:将种子浸泡在水(冷水和热水)、牛尿(5%、10%、15%和20%的浓度)、牛粪浆、酪乳、堆肥茶和Agnihotra灰中,并与未经处理的对照进行比较。除酪乳对迷迭香种子发芽率有不利影响外,播前处理均使迷迭香种子发芽率高于对照。在不同处理中,牛粪浆处理的种子萌发率为46.7%,牛尿处理的种子萌发率为5.0%,显著高于对照组的9.7%。牛粪浆处理还记录了均匀和早期发芽(9天开始和43天完成),导致发芽率(1.4)显著高于对照。牛粪浆处理的种子叶片数、根长和幼苗活力最高,其次是牛尿(5.0%)。

期刊介绍: Biological Agriculture & Horticulture aims to act as the central focus for a wide range of studies into alternative systems of husbandry, and particularly the biological or organic approach to food production. The Journal publishes work of a sound scientific or economic nature related to any aspect of biological husbandry in agriculture, horticulture and forestry in both temperate and tropical conditions, including energy and water utilization, and environmental impact.
