On the treading-pressure effects and the mowing effects on the growth of American and European lawn grasses

Abstract

Experiments were carried out to know the treadingpressure effects and the mowing effects on the growth of American and European lawn grasses (Kentucky bluegrass, colonial bentgrasses-Highland bent and Astoriabent, redtop, Bermudagrass, Chewings fescue and Italian ryegrass) in Japan, and the following results obtained.
(1) By the tread, the height of them became low, and by the moderate tread, their weight (fresh and dry measure), the amount of stems, stolons and roots increased, but by the over tread, all decreased, while the length of roots was not influenced. As a rule, Highland bent, Astoria bent and Bermudagrass were comparatively strong to the tread, while Kentucky bluegrass and Italian ryegrass were comparatively weak.
(2) By the mowing, their weight (fresh and dry measure), the height of them, the amount of stems and stolons and the length of roots decreased, and by the moderate mowing, the amount of stems, stolons and roots of some kinds increased, but by the over mowing, all decreased. As a rule, Bermudagrass was comparatvely strong to the mowing, while Kentucky bluegrass and Italian ryegrass were comparatively weak.
