Response of Rumex vesicarius, L. plants to three different growth regulators [electronic resource].

Includes references.

Response of Sorrel (hommaidh) plants to three various growth regulators; i.e. naphthalene acetic acid (NAA), gibberellic acid (GA₃) and mefluidide was studied during two growing winter seasons of 2010 and 2011, at the Department of Plant Production, College of Food and Agriculture Sciences - King Saud University. Four different concentrations sprayed onetime for each growth regulator applied as follows; GA₃ (0, 10, 20 and 30 ppm), NAA (0, 50, 100 and 150 ppm) and Mefluidide (0, 500, 1000 and 2000 ppm). The used concentrations varied significantly in their effects on the vegetative growth and flowering characters of the plants. Sprayed plants with GA₃ showed significant increase in plant height, number of leaves per plant, length of inflorescences stalks and root length. Irrespective of concentration, mefluidide produced the largest leaf area, number of inflorescences and number of flowers per plant. It also caused faster initiation of flowering however, GA₃ and NAA delayed it. Use of NAA reflected increasing number of branches. Generally, foliar application of low concentration level of mefluidide 500 ppm was the best treatment for obtaining better plants growth, represented in a maximum leaf area per plant with higher number of inflorescences per plant as well as faster flowering.
