Abstract
The root (wilt) of coconut. Is a disease of unknown the etiology, and of con-sidersble economic importance to Kerala. Root decay It a common phenomenon associ-ated with root (wilt) disease wherein 12 to 90% root rotting has been reported in diseased palms. A study was therefore conducted to induce root production In root (wilt) affected coconut palms and to regenerate the damaged root system. Root (wilt) diseased middle aged pelms were used for this study. Growth hormones IBA and NAA, pehnols and amino acids In different concentrations singly and In combinations were applied by the lanolins pasta method to the base of the stem (near bole region) after debarking the same at ground level. The points of application were then covered with soil which was kept moist during the rainless period by water-Ing. Root initiation was observed between six months to one year after treatment. The palms which .received the treatment IBA 500 ppm + phenols 400 ppm each, produced the maximum number of roots. The next effective treatment was found to be NAA 500 ppm + Glutamic acid 500 ppm.
