The study involved in testing the effects of two amended organic media （loam ＋ sheep manure and loam ＋ peat moss （1：1）） and different concentrations of seaweed （sea force 2） extract including （0, 0.5, 1, 1.5 and 2 mL/L） on growth and flowering of Periwinkle （Vinca rosea） plant. The results showed that growing vinca plants in peat moss medium and spraying sea force 2 extract with low concentrations especially 0.5 mL/L resulted in positive significant difference in vegetative and flowering characteristics.展开更多
