Characters of leaf water absorption for three turfgrasses.

The absorption on leaf surface of three turfgrasses was measured through an experiment performed by living organism, and also the relationships between leaf area and total amount of water absorption were obtained by a small-scale turf. The results showed that the relationship between water absorption rate and time accorded with power function, it was high at the beginning, and then gradually leveled off. Total amount of water absorption at per leaf area and per dry weight were different. In the amount of saturated leaf weight, per unit of leaf area of tall fescue was the highest, while per unit dry matter of Kentucky bluegrass was the highest. In addition, the equation between water absorption amount of lawn canopy leaves and mowing height was derived and validated.
