| Abstract | ||
| Improving the growth and productivity of crops, including ornamental bulbs, via bio-stimulants is a very imperative topic since plant bio-stimulants have been recognized among the best agricultural practices. Polianthes tuberosa L. (Tuberose) is one of the most important flowering bulbs crop worldwide due to the excellent fragrance of spike florets. Seaweed and humic acid are among the multifunctional bio stimulants that improve the plant development. However, their impact on the production of flowering bulbs including tuberose is not well-investigated. Hence, the current study aimed to bridge this gap. The objective of this study was to investigate the effects of exogenous application of seaweed and humic acid on the growth and flowering characteristics of tuberose. Seaweed was applied at 0, 0.5, 1 and 2 mL L-1 however, humic acid was used at 0, 0.2, 0.4 and 0.8 g L-1. The results showed that the leaf length, number of leaves, spike length, spike diameter, number of florets as well as fresh and dry weights of spikes were markedly enhanced as a result of applying seaweed or humic acid treatments compared to the control. Both applications decreased the period required until flower beginning relative to the control. Further, the total chlorophyll content, carotenoids, total carbohydrates and endogenous phytohormones were also improved due to seaweed or humic acid applications. Applying seaweed at 2 mL L-1 combined with humic acid at 0.4 g L-1 was the most effective treatment. Seaweed and humic acid may be applied as promise and ecofriendly bio-stimulants to enhance the growth and productivity of tuberose. | ||
