Lee, J.S. (University of Seoul, Seoul, Republic of Korea)
To improve the graft-take percentage and quality of the saddle grafted ruby balls with Hylocereus trigonus as rootstocks during summer, the plant growth regulators (PGRs) were treated 5 days after grafting, Globe diameter and root numbers were largest with 90 mgㆍL-¹ indole-3-yl butyric acid (IBA) treatment regardless of the measured dates from grafting, while 75 mgㆍL-¹ ancymidol showed longest root length. The chlorophyll contents was highest with 100 mgㆍL-¹ diniconazole and lowest with 90 mgㆍL-¹ IBA.
