Anthocyanin content of coriander (Coriandrum sativum L.) leaves as affected by salicylic acid and nutrients application

摘要

A field experiment was conducted to assess the influence of salicylic acid and some important macro and micro elements on anthocyanin content of coriander (Coriandrum sativum L.) leaves as antioxidant, at the experimental field of Gorgan University, Golestan, Iran, in 2007. Based on the soil analysis nitrogen, phosphorus, potassium and zinc fertilizers were added to the experimental field with 75, 45,170 and 30 kg/ha, respectively. Salicylic acid at the rate of 10-4molar, iron, magnesium, molybdenum and boron in a rate of 2-3 g/L were sprayed on foliage part two times at 40thand 47thdays after sowing. Other plots were sprayed with distilled water. Results showed thatapplication of zinc and nitrogensignificantly increased and decreased anthocyanin contentin coriander leavesas compared with control and led to the highest and the lowest rates of anthocyanin, respectively. Also other treatments did not show significant difference than controlbut phosphorus and potassiumhad negative effect on anthocyanin content, while other treatments increased it insignificantly
