Foliar application of nano-silicon enhances drought tolerance rate of pot marigold (Calendula officinalis L.) by regulation of abscisic acid signaling.

ABSTRACT: Pot marigold (Calendula officinalis L.) is an herbaceous ornamental and medicinal plant. Climate models predict a reduction of precipitations and increasing the average temperature. Therefore, agricultural plants will be more frequently exposed to water deficit stress. To investigate the influence of nano-silicon foliar application (0, 50, 100, and 200 mg L^- 1) on the alleviation of drought stress (100, 75, and 50% Field capacity (FC)) adverse effects on marigold plant characteristics, a factorial experiment was conducted based on a completely randomized design with three replications. The chlorophyll content of plants treated with nano-silicon 200 mg L^- 1 decreased by 8.39% when drought stress increased from 100 to 50% FC. In line with electrolyte leakage percentage,
