    In the previous paper, the authors reported the germination of the seeds of American and European Iawn grasses (Kentucky blugrass, colonial bentgrasses Highland bent and Astoria bent, redtop, Bermudagrass, Chewings fescue and Italian ryegrass) in Japan and the repression effects on their growth. The present experiments were carried out to know the irrigation effects and the sunbeam effects on their growth, and the following results obtained.
    (1) By the irrigation, the growth of American and European lawn grasses were quickened and the height of them increased.Irrigation of 10 litres per 3.3m2 once or twice a day were effective.
    (2) By the results of sunbeam deficiency, their weight (fresh and dry meaure), the amount of stems and stolons, the length and amount of roots decreased, and the height of them increased. Redtop was least influenced by sunbeam deficiency, while Bermudagrass was most influenced.

    This stem cuting were tested in the 130day's duration, using shades which were divided into three grades.
    And the treatments were done spray using solution of Sodium α Naphtalen, Rootone, banding of black tape and the leaves spray of Urea.
    Result;
    (1) 60-100% of rooting percentage was obtained for what have been regareded have to root.
    (2) If appears that it is adnisable to keep shading for a long period.
    (3) Good results were obtained under shades, covering not so thick permiting sun light a little.
    (4) No relation was found between grades of shading and ways of treatments, so far as their rooting ratio is concerned.

    5-1 We can see splendid growth in Cynodon dactylon (Bermudagrass) by supplieing N-manure as compared with Zoysia japonica.
    5-2 The sprout indicates high rate, and rebirth forth is surpassing.
    5-3 It appears over tred site or solidsoil.
    5-4 I think, Cynodon dactylon is adapted with “Overtreding Turf”.
