The effect of accelerating the rooting of cuttings rooting cuttings. Mulberry eaten fresh Chiang Mai to determine the appropriate use of hormone concentrations and the best way to stimulate the rooting of mulberry eaten fresh. Chiang Mai. The experimental design was Completely Randomized Design (CRD) number 4 Rep. 3-the save data, the number root length characteristics include root and root rating. The test showed that a try. Root length is the difference statistically significant. For many roots And the roots There is no difference statistically. This trial showed that growth in average root length hormone NAA concentrations 3,500 ppm. as a result, mulberry twigs been reviewed with the highest average root length is 10.19 a centimeter. Followed by the hormone NAA concentrations 4,000 ppm. as a result, root length average is 9.84 b centimeter. And the average number of root hormone NAA concentrations 3,500 ppm. there is a root of the average maximum is 14.3 roots. This is the hormone that causes the roots of the mulberry twigs eaten well when compared to other hormone concentrations, and others. In this experiment, the use of hormone NAA intensity resulted in the emergence of roots and root best a minor hormone IBA. The use of this hormone, when compared with the use of hormonal agents B1 with water (control) NAA and IBA were treated hormone rooting hormone better trade B1 and water (control).
