UJI STEK PUCUK DAMAR (Agathis loranthifolia Salisb.) PADA BERBAGAI MEDIA DAN ZAT PENGATUR TUMBUH

Abstract

Pohon damar ( Agathis loranthifolia Salisb.) merupakan pohon serbaguna yang kayu dan resinnya memiliki nilai komersial tinggi. Perbanyakan secara generatif sulit dilakukan karena benih damar tergolong benih semi-rekalsitran (cepat rusak). Perbanyakan vegetatif merupakan alternatif untuk perbanyakan bibit damar. Penelitian ini bertujuan untuk mendapatkan informasi tentang besarnya pengaruh media ( zeolite , serbuk sabut kelapa : arang sekam padi (2:1 v/v), serbuk sabut kelapa : sekam padi (2:1 v/v)) dan zat pengatur tumbuh (rootone-F, IBA 100 ppm, IBA 200 ppm, IBA 500 ppm, IBA 1000 ppm) terhadap perkaran stek damar. Perakaran stek dilakukan di ruang perakaran stek sistem KOFFCO. Parameter yang diamati adalah persen stek berakar, jumlah akar, panjang akar dan biomasa akar. Media dan hormon tumbuh mempengaruhi keberhasilan stek damar. Media campuran serbuk sabut kelapa + sekam padi (2:1) merupakan media terbaik untuk perakaran stek damar. Media ini dapat menghasilkan persen berakar stek damar 67%, panjang akar 5,17 cm, jumlah akar 2,62 per stek, biomassa 0,09 gram per stek. Hormon tumbuh hanya berpengaruh nyata pada panjang akar stek damar. Konsentrasi hormon tumbuh optimum untuk perakaran stek damar adalah IBA 200 ppm.
