Sterilisasi Dan Penggunaan Zat Pengatur Tumbuh Bap (Benzile Amino Purin) Terhadap Pertumbuhan Eksplan Tunas Pisang Abaka (Musa Textilis Nee) Melalui Teknik In Vitro

This study aims to determine the most appropriate method and sterilization technique for the growth of abaca weevil shoot explants taken directly from the field and to determine the effect of the dose of growth regulator BAP (Benzile amino purine) on the growth of abaca feed. explants (Musa textilis Nee). through in vitro techniques. This study uses the multilevel sterilization method and the sterilization method using direct observation, namely when the explants have become shoots. The results showed that the appropriate sterilization method was a fixed sterilization method with bayclin treatment with a concentration of 30% for (30 minutes), 20% for (20 minutes), 10% for (10 minutes) with several techniques carried out so that the explant was successful. grow, namely in the 6th technique. Induction of shoots of abaka banana weevil explants in BAP treatment was best at 7 ppm treatment by producing 5 shoots. With the height of each shoot, namely: a (0.9 cm), b (0.3 cm), c (0.4 cm), d (0.4 cm), and e (0.5 cm)

Pengaruh Pemberian Trichoderma sp. Dan Plant Growth Promoting Rhizobacteria (PGPR) Terhadap Pertumbuhan Akar Stek Pucuk Tanaman Krisan (Chrysanthemum morifolium R.)

This study aims to determine whether there is an interaction and influence of concentration from the administration of Trichoderma sp. and Plant Growth Promoting Rhizobacteria (PGPR) on the root growth of chrysanthemum plants. This research was carried out at the Center for Protection and Quality Testing of Horticultural Food Crops and the Screen House Office of the Center for Seeds, Agricultural Nurseries and Agrotourism Show Window, Tomohon City. This research was conducted from June to August 2022. Primary data was obtained from the results of the study including the variables root length, root weight, and percentage of living cuttings while secondary data was obtained through books obtained from local bookstores and the internet via Google Scholar in the form of books, articles journals and theses related to research topics. The results showed that the longest plant roots were produced at the concentration level of Trichoderma sp. solubility of 107 and PGPR 15ml/l (T1P3) with an average of 11.6 cm and the heaviest roots were produced at the concentration level of Trichoderma sp. solubility 109 and PGPR 10ml/l (T3P2) with an average of 0.49 gram
