      Abstract
      Pengadaan bibit dari cabutan alam seringkali mengalami hambatan karena persentase hidupnya yang rendah akibat kerusakan akar. Penelitian ini dilakukan untuk melihat daya hidup cabutan Cinnamomum iners dan Sandoricum koetjape serta melihat pengaruh penggunaan perangsang akar dan daun terhadap pertumbuhan cabutan alam. Rancangan percobaan yang digunakan adalah rancangan acak lengkap faktorial. Dua faktor perlakuan yang diujicobakan adalah faktor pemotongan akar (P) dan perangsang akar dan daun (B). Faktor P meliputi : P0 = tanpa pemotongan akar dan P1 = dengan pemotongan akar; sedangkan faktor B meliputi B0 = tanpa perangsang akar dan daun B1 = konsentrasi 2.50% B2 = konsentrasi 1.25% B3 = konsentrasi 0.83%. Pemberian perangsang akar dan daun pada Cinnamomum iners dan Sandoricum koetjape dapat meningkatkan jumlah daun dan panjang akar. Perlakuan pemotongan akar dapat meningkatkan pertumbuhan tinggi pada Sandoricum koetjape. Perlakuan yang tepat untuk meningkatkan pertumbuhan Cinnamomum iners dan Sandoricum koetjape adalah perlakuan tanpa pemotongan akar dan pemberian perangsang akar dan daun dengan konsentrasi 0.83%.
       
      Stock of the wilding often had problem because of the lower growth rate due to root damage. The objectives of this research were to consider the live rate of Cinnamomum iners and Sandoricum koetjape’s wilding and to consider the effect of root and leaf’s stimulant to the wilding’s growth. Factorial in completely randomized block design was used in this experimnent. The first factor was root and leaf’s cutting (P0 = no cutting, P1 = with cutting) and the second one was root and leaf’s stimulant application in concentration B0 = without stimulant, B1 = 2.5%, B2 = 1.25% and B3 = 0.83%. The used of root and leaf’s stimulant on Cinnamomum iners and Sandoricum koetjape’s wilding can stimulate the growth of leaves and root. The root’s cutting stimulated Sandoricum koetjape’s height. The combination treatment of root and leaf’s stimulant 0.83% and without root’s cutting showed the best effect to stimulate the growth of Cinnamomum iners and Sandoricum koetjape’s wildings.
