RESPON PEMBERIAN HORMON TUMBUH DAN MIKORIZA TERHADAP PERTUMBUHAN STEK RAMIN (GONYSTYLUS BANCANUS (MIQ.) KURZ)
Get PDFThis study was conducted to determine the effect of growth hormones and mycorhyza application on the growth of ramin cuttings. A Completely Randomized Design with 5 replicates was used in this study. The experiment consisted of two stages i.e hormon treatments (control, Rapid root, Root Up, IBA 250 mg/l, IBA 500 mg/l, IBA 1000 mg/l), Fusarium and mycorhyza applications. The result showed that the highest number of root was obtained from Root Up (12,83 cm), while the lowest was from Fusarium treatments (4,67 cm). IBA 250 mg/l enhanced the number of roots and the length of root significantly but not stimulate the development of new leaf. While mycorhyza application improving the growth of the new leaf and the root development of ramin
STUDI KERAGAMAN JENIS, KANDUNGAN GIZI ESENSIAL DAN KALSIUM OKSALAT DIOSCOREA DI PULAU BALI DAN LOMBOK
Get PDFDioscorea tuber has many benefits, for example as food or as traditional medicine. The high carbohydrate and protein contents make this plant suitable as a food. However, the presence of crystal oxalate, that causes irritation is an disadvantage aspect on the development of this species. Both of wild and cultivated species will assure the gene flow which is important in efforts to improve the tuber quality should be examine further. This research aimed to observe the biodiversity of Dioscorea in Bali and Lombok, to recognize the utilization and to reveal their nutrients (carbohydrate, protein and fat) and also the contents of calcium oxalate. The results showed that there are five Dioscorea spesies, namely Dioscorea alata L. (ubi) (11 cultivars), Dioscorea esculenta (Lour.) Burkill (ubi aung), Dioscorea hispida Dennst. (gadung), Dioscorea bulbifera L. and Dioscorea pentaphylla L. The highest carbohydrate content (87,42% ) is found in D. alata (ubi ungu cultivar) from Lombok, while the highest protein content (5,05%.) is found in D. alata (ubi dadap cultivar) from Singaraja, Bali. Furthermore, the highest percentage of fat content (0,85%) is found in D. bulbifera from Karangasem, Bali, whereas the high quantity of glaucomannan (44,52%.) id found in D. pentaphylla from Tabanan, Bali, while D. esculenta from Jembarana, Bali has the highest calcium oxalate (0,57%), and D. alata (ubi injin cultivar) from Karangasem, Bali has the least calcium oxalate (0,18%)

ANATOMI DAUN PIPERACEAE DARI KAWASAN GUNUNG SLAMET, JAWA TENGAH
Get PDFLeaf anatomy of Piperaceae from Gunung Slamet, Central Java has made with standard paraffin and paradermal method. The results showed that Piperaceae has dorsiventral leaf, hypostomatatic or amphistomatatic, tetracytic and cyclocytic stomata type. Hypoderm tissue exist in upper and/or lower part of leaf, mesophyll was arranged by 1-2 layers of palisade and 2-7 layers of sponge tissue. There were 3 types of trichome i.e. glandular trichome which had globose cell with short stalk, bicellular glandular trichome and multicellular & uniseriate non-glandular trichome. The shape of the crystal of Piperaceae from gunung Slamet are sand, needle, drusse or prismatic which distributed in hypodermis, mesophyll and midrib. Piperaceae petiole was arranged by open or sometimes closed circle vascular bundles. These open vascular bundles were crescent shape or resemble to U and V shapes
