Fig. 1From: Tolerance of citrus plants to the combination of high temperatures and drought is associated to the increase in transpiration modulated by a reduction in abscisic acid levelsPhenotypic traits of citrus plants in response to a combination of drought and heat stress. Intact sprouts (%) of Carrizo and Cleopatra seedlings subjected to drought and heat stress (40 °C) in combination for 10 days. For each genotype, asterisks denote statistical significance with respect to initial values at p ≤ 0.05Back to article page
