Abstract
Plant growth regulators now play a large roll in agricultural practices in many parts of the world. Since agriculture is a major enterprice in the Ryukyus, it was imperative that this University initiate research with these chemicals so that they also may be used here in the future. Although there are many of these chemicals which can be used, only a representative number were used in these preliminary tests. These were of two types; namely, inhibitory and stimulatory. The former was used to control Oxalis violacea L. and the latter was used to induce roots on cuttings of Chrysanthemum morifolium. The inhibitory chemicals, or herbicides as they are now called, were effective in reducing growth of the Oxalis of varying degrees. Dalapon at 20 pound per acre gave excellent control (Table 1). The most significant findings of these test were that, Dalapon, Kuron and Esteron 245 greatly reduced the number and size of Oxalis bulblets. In one instance they were reduced from 305 bulblets per 20 square centimeter to 19 per square centmeter (Table 2). The newer chemicals used to promote roots of Chrysanthemum cuttings were just as effective as some of the commercial rooting compounds. The materials " 3-(2, 4-DP) and 4-(2, 4-DB) " produced many roots and the naphthaline and indole materials produced fewer but longer roots (Table 3). These and other plant growth regulators need further testing here before they can be recommended for general use by the farmers and nursery men.
