Abstract
The chilling of a part of the root did not cause any significant decrease in shoot water content (Fig. 1A). In spite of this RWP dropped significantly already after 2 h of root chilling and remained clearly below that of control plants for the whole treatment period ( ) f f Fig. 1B . ABA levels in chilled roots increased a ter 4 h o treatment but much more so in the chill tolerant genotype than in the sensitive one (Fig. 2B). Similarly, ABA concentration in xylem sap and ABA delivery rates via transpiration stream in treated plants were above those of control plants, especially in the chilling tolerant genotype (Fig. 3). The pH value of xylem sap increased significantly during root chilling compared to control plants, especially in chill tolerant genotypes (Fig. 4). Fig. 2. Abscisic acid (ABA) level in leaves (A) and in the part of the root protruding from the pot (B) and chilled at 8 oC in three maize genotypes. Nimba and S277 are chill tolerant genotypes and S41791 is chill sensitive. Vertical bars are the least statistical difference at p ≤ 0.05 within each genotype and each parameter measured.
