spp. are soil-borne pathogens that cause damping-off and root rot diseases in many plant species such as cucumber. In the current study, the effect of dried roots-stems and leaves of (Sprengel) R.
The sepal of the Hibiscus sabdariffa L. plant is economically significant, but separating seeds from sepals during harvest is challenging; parthenocarpy (seedless fruit development) could reduce labor costs and increase profits.
The study examined the effects of gibberellic acid (GA), melatonin (M), and indole acetic acid (IAA) on inducing parthenocarpy in these plants, using varying concentrations and a randomized design.
Results showed that specific combinations of GA (800 and 900 ppm), IAA (1000 ppm), and M (100 and 200 ppm) significantly enhanced parthenocarpy production, while the control group had the highest mature seed
