Floral induction by gibberellic acid in Impatiens balsamina, a qualitative short-day plant.

abstract：MAIN CONCLUSION:Trehalose increased drought tolerance of tomato plants, accompanied by reduced water loss and closed stomata, which was associated with the upregulated ABA signaling-related genes expression, but not in ABA accumulation. Drought is one of the principal abiotic stresses that negatively influence the grow...
