Response of two seed-grown artichoke cultivars to GA3 and melatonin treatments

Abstract

Abstract Background Globe artichoke Cynara scolymus L. is an important vegetable crop. Poor crop stand due to the low ratio of stumps surviving is the common problem which occurs with using vegetative parts. The current study evaluated two seed-propagated cultivars of artichoke: treated by GA3 and melatonin applications in newly reclaimed land. Results Results showed that Imperial Star produced higher values of vegetative growth, yield productivity, and chemical contents, compared with Romanesco cultivar. GA3 foliar application treatment ranked the first to increase vegetative growth, yield productivity, and chemical contents, followed by melatonin treatment, compared with untreated control. Conclusion It could be concluded that the use of GA3 and melatonin were favorable for the production of both artichoke cultivars: Imperial Star and Romanesco. The highest productivity was achieved by foliar application of GA3 to Imperial Star cultivar.
