原始语种摘要: Decent taste and the salt and drought tolerance of purslane (Portulaca oleracea L.) make it a potential vegetable crop for the future. This study investigates the effects of foliar application of 5-aminolevulinic acid (5-ALA), a new plant growth regulator, on the growth, mineral composition, and bioactive compounds of purslane. Three different levels of 5-ALA (0, 25 and 50 mg L-1) were sprayed at 1) two leaved stage and 2) upon the onset of inflorescence appearance on purslane seedlings. Results showed that 5-ALA application enhanced biomass accumulation in the plant shoot and increased shoot length. Concentration of nitrogen, potassium, magnesium, zinc and iron increased in the shoots of 5-ALA treated plants, while the calcium concentration remained unaffected. Phenolic compounds of the...
