Review - All MASP1 Positives As well as Drawbacks

ancova analysis carried out using the R programming environment (R Core Team 2012) was used to test if the slope of the relationship MASP1 between vein and stomatal density was the same regardless of whether changes were induced by VPD or by irradiance. R2 was also calculated for both relationships. The relationship between transpiration and leaf hydraulic conductance under high and low VPD was plotted against the same relationship in plants grown under high and low irradiance to test whether transpiration was maintained at rates appropriate for the hydraulic capacity of the vascular system. R2 was calculated for the relationship between plants grown under contrasting irradiance. In T.?ciliata, VPD had a substantial effect on leaf size and a small but significant effect on vein and stomatal density (Fig.?1). Leaves from plants grown under high VPD were about one-third (38%) the size of those grown under low VPD (P?PFI-2 supplier stomata (P? This response was considerably less than the proportional response expected if vein and stomatal density were controlled by the ��dilution�� effect of leaf area (P??0.05) (irradiance data from Carins Murphy et?al. (2012) (Fig.?3). Epidermal cell size did not vary significantly between plants grown under high and low VPD (P?>?0.05), although the stomata of plants grown under low VPD were slightly (14%) larger than those of plants grown under high VPD (P?AZD6738 cell line total number of epidermal cells per leaf was proportional to leaf size (Fig.?4). The total number of stomata and length of veins per leaf were also related to leaf size, although these relationships were not directly proportional, as the total vein length per leaf in plants grown under low VPD was 9% less than expected if directly proportional to leaf area, and the total number of stomata was 24% less than would be expected if directly proportional to leaf area (P?
