Abstract

Taro (Colocasia esculenta (L.) Schott) is an important tuber crop, grown widely in humid tropics and a source of carbohydrate for many people in Asia, Africa, and the Pacific islands. The leaves and stalks of taro are used as vegetable, as they contain a high protein that is useful for people diet in developing countries. Taro is underutilized plant that has potency as an alternative food.Plant propagation of taro is usually done by using its rhizome or stolon so that the genetic diversity is very limited. In vitro and irradiated techniques can increase its genetic diversity and multiply the plant that has superior quality and quantity.Taro "Ketan" grown tissue culture have been irradiated with gamma rays S Gy and 10 Gy were planted on two different environmental locations.There were many variants as the results of these treatments. Gamma rays and environmental locations caused genotype changes that were stolon number, plant height, corm fresh weight, and leaf blight disease.Gamma rays caused morphological changes that were orientation, undulation, outline of sinus, margin of lamina,and petiole color.

Abstract

Cendana {Santalum album L.)merupakan tumbuhan yang termasuk dalam kelompok suku Santalaceae. Sebagai anggota kelompok tumbuhan parasit, pada fase pertumbuhannya cendana memerlukan interaksi dengan tumbuhan lain yang berfungsi sebagai inang, melalui alat-alat kontak yang disebut haustorium. Sistem perakaran cendana, di mana padanya haustoria berkembang, lebih didominasi oleh pertumbuhan horizontal. Jenis tanaman inangnya tidak spesifik, sehingga pemilihan jenis tanaman inang untuk cendana dapat disesuaikan dengan model-model yang akan dikembangkan yaitu model agroforestri atau konservasi.

Abstract

S. DANIMIHARDJA,SAEFUDIN,F. SYARIF & N.SETYOWATMNDARTO. 1987. The growthof some fast-growing legume species in the field after seedling inoculation with Rhizobium.Berita Biologi 3(8): 377 - 381.Eleven species of fast growing legumes were grown in the field after their root seedlings were inoculated with two selected strains of Rhizobium sp.The results indicated that Acacia villosa was the fastest growing species (324.8 cm in height and 28.35 mm in diameter after 13 months of planting).The slowest one was Albizia procera (86.20 cm and 10.45 mm).The statistical analysis indicated that between species there were highly significant differences either in height or in diameter of the plants. Between treatments there was significant difference in diameter, but not in height.The interaction between treatments and species was highly significant difference in diameter, but not significant one in height. After 13 months of planting 6 species had already produced pods,namely Acacia villosa,Albizia lebbeck,Bauhinia acurninata, B. purpurea, Caesalpinia pulcherrima and 7 C.sappan.The death rates were ranging from 19% (in Albizia chinensis),30%(in A. falcatariaj, 46% (in A. procera),47% (in A. lebbeck), until 50% (in Acacia auriculiformis).

Abstract

SAEFUDIN & R. SANTOSA.1986.The effect of nitrogen, phosphorous and potassium fertilizers on the growth of Ipomoea aquatica Forst. Berita Biologi 3 (5): 214-218.Experiments to study the effect of nitrogen, phosphorous and potassium fertilizers on the growth of Ipomoea aquatica, a leafy vegetable, were carried out on four sites, i.e. in the villages of Teluk, Karangklesem, Purwokerto Kulon and Sumampir of the district of Banyumas respectively. The rates of application used were 0, 125, 250 and 375 kg of urea, triple superphosphate or potassium chloride per ha. The nitrogen fertilizer increased significantly the growth of Ipomoea aquatica with optimum rate 250 kg of urea per ha. Potassium chloride increased slightly the stem elongation, but not the vegetable yield, while the phosphorous fertilizer did not show any significant effect.Among sites, the highest yield was obtained from the plot in the village of Teluk, followed by Karangklesem, Purwokerto Kulon and Sumampir in decreasing order.
