Abstract

The effect of coating the seed of clover crops by water absorbing seed process (WASP) technology pelletization on its germination capacity was studied in conditions of diverse drought intensities simulated by different concentrations of polyethylenglycol (PEG) 8000 solution. Drought resistance was monitored in the seed of five fodder clover species: L., L., L., Medik. and Scop. In the seed of given plant species, germination capacity was determined along with the share of dead and hard seeds. Although the coating significantly ( < 0.05) affected the drought resistance of seeds, the germination capacity increased only in conditions of milder drought (simulation with PEG: 0.1-0.3 mol). With the increasing intensity of drought induced by higher PEG concentrations (0.4-0.7 mol) the number of germinable seeds demonstrably decreased and the number of dead seeds increased in the coated seed as compared with the uncoated seed. The coated seed can be appropriate for use in , and , while the uncoated seed can be used in and .

摘要

通过吸水种子处理（WASP）技术造粒对三叶草作物种子进行包衣处理，研究了其在不同浓度聚乙二醇（PEG）8000溶液模拟的不同干旱强度条件下对种子发芽能力的影响。对5种饲料三叶草种子的抗旱性进行了监测，分别为：白车轴草、红车轴草、草莓车轴草、天蓝苜蓿和杂三叶。在给定植物物种的种子中，测定了发芽能力以及死种子和硬种子的比例。虽然包衣显著（P<0.05）影响种子的抗旱性，但发芽能力仅在轻度干旱条件下（用PEG模拟：0.1 - 0.3摩尔）有所提高。随着PEG浓度升高（0.4 - 0.7摩尔）导致干旱强度增加，与未包衣种子相比，包衣种子中可发芽种子数量明显减少，死种子数量增加。包衣种子适用于[具体地区1]、[具体地区2]和[具体地区3]，而未包衣种子可用于[具体地区4]和[具体地区5]。 （注：原文中部分植物学名后的“L.”“Medik.”“Scop.”等未明确含义，以及部分地区名称未给出具体内容，翻译时保留原文形式）
