Abstract
To encourage the production of seedlings, it is necessary to give plant growth regulatory with sufficient doses and the right time of soaking time to meet the needs of seedlings to grow more optimally. This study aimed to determine the response of the several types of natural plant growth regulatory and the duration of soaking time to growth of lime cuttings. The design used in this study was a Randomized Block Design with two factors, first factor : the concentration of several types natural plant growth regulatory consist of control, 40ml/l bamboo shoots, and 400g/l sprout extract. Second factor : Soaking time ( 2 , 3 and 4 hour). The variables were shoot length, number of leaves, root length, number of roots, wet weight and dry weight of the plant, also live percentage. The result showed that plant growth regulator from bamboo shoots and sprout extract combined with 4 hour soaking time have great value for shoot lengt at 30 DAP, besides at 75 DAP bamboo shoots plant growth regulatory showed the great value if combined with 3 hour soaking time.
