Abstract

H. IMAMUDDIN. 1987.The failure of pods and seeds development of Bauhinia tomentosa L. Suppl. Berita Biologi 3 : 35 - 37.Microscopic,observation to study the failure of pods and seeds development of Bauhinia tomentosa L. was conducted.Several buds,6 - 21 mm long, were diserved with paraffin method.The results showed that the failure of pods and seeds development of B. tomentosa were not caused by either flower morphology, pollen fertility or nticrospore development,but by abnormal development of saccus embrionalis,followed by incomplete development of egg cell,which made the flowers aborted before receptive.

DARJONO & DEWI MALIA PRAWIRADILAGA 1987. Effect of level of Phaseolus lunatus seeds in the native chicken ration on feed consumption, and body weight gain Suppl. Berita Biologi 3 :61 -65. The experiment was aimed to obtain a basic guide of the amount of P., lunatus in chicken ration during growing period. Observation using 25 cockerels and 25 pullers, was based on Completely Randomized Design. The treatment consisted of level of P. lunatus in the ration, namely RK (as control ration), RI, RII, RIII, and RIV, containing 0%, 5%, 10%, 15%, and 20% respectively. Data was analyzed using Analysis of Variant, and the difference was tested by Honestly Significant Different Test. The results showed that the level of P. lunatus up to 20% had no significant effect (P > 0,05), on feed consumption and body weight gain during growing period. The highest feed efficiency for the cockerels was RI (0,0593) followed by RK (0,0559), RIII (0,0506), RIV (0,0478), and RII (0,0350) respectively; whereas for the pullets was RII (0,0267) followed by RK (0,0262), RI (0,0225), RIII (0,0220), and RIV (0,0102) respectively.

Abstract

RAZALI YUSUF.1987.The influence of Phytophthora colocasiae on distribution of Colocasia esculenta varieties in Jawa island. Suppl.Berita Biologi 3 : 17 - 19.Field observation on varieties of Colocasia esculenta var.esculenta and C.esculenta var.antiquorum showed that the distribution of these two botanical varieties has distinct pattern. The population of C.esculenta var.esculenta are more prevalent in the lowland, whereas the population of C.esculenta var.antiquorum are confined to higher elevations.Differences in their succeptibility to the attack of the fungus Phytophthora colocasiae'it one important factor which determines the natural distribution of these two botanical varieties.

S.H. RAHAJU, H.J.D. LATUPAPUA & S.ABDULKADIR. 1987.The evaluation of some Rhizobium strains as the inoculants and then effects on the growth of Albizia chinensis and A. lebbeck. Suppl. Berita Biologi 3 : 38 - 44. A study was conducted to evaluate some Rhizobium strains on the growth of A. chinensis and A. lebbeck and used them as the inoculants. Three experiments were carried out under the green house conditions, the 0.5 gallon plastic pots were filled with sterile sand as the medium. The experimental design was carried out Completely Randomized Design with five replicates. The first and second experiments were implemented on A chinensis which were consisted of 10 and 7 Rhizobium strains respectively, whilst the third experiment was implemented on A. lebbeck by using 18 Rhizobium strains. Each experiment was lasted in three months. The parameters of investigation were dry weight of total plants, the plant parts above the medium surface, the plant parts under the medium surface, the roots and the nodules respectively, also was counted the symbiotic capacity. The results showed that all inoculated plants produced nodules except the plants that were inoculated with Rhizobium sttains Cg and Ri. The best inoculant was strain number 34 which implemented on A chinensis and A lebbeck.

Berita Biologi. 3 : 66 - 69. .The stem borer insect of Albizia falcataria causes not only damage of the trunk, but also reduce the quality of the wood.Control of the insects borer using silviculture method require knowledges about its nature, behaviour and other ecological factor.The study of damage to Albizia stand by insects borer was carried out at the Albizia plantation, Rancamaya, Bogor.Observation were made on the group stands of 2 - 3; 6 - 7 and 9-10 years old respectively.The results indicate the Albizia stand are attacked by two species of insect borer, namely Xystrocera festiva Pasc.(Coleoptera : Cerambycidae) and Arbela tetraonis Moore. (Lepidoptera : Arbelidae).X festiva attacked stands of all group categories, while A. tetraonis attacked only the young stands or the branches of old stands. The damage caused by X. festra is up to 20% of the period 8-10 years, while A tetraonis caused damage up to 30% of the same class.

Abstract

MUSTAID SIREGAR. 1987.The comparison of ground vegetation under four forest plantations in Candikuning, Bali. Suppl. BeritaBiologi. 3: 45-50.The ground vegetation under four forest plantations of different species in Candikuning (Altingia excelsa, Manglietia glauca, Agathis dammara, Pinus merkusiij have been investigated by using quadrat method. The results showed that the highest index of similarity was 53,06% between A. dammara and P. merkusii plantations, and the lowest index of similarity was 18,21% between A. excelsa and P. merkusii plantations. The species composition and community stability of these ground vegetations under "each plantation differed. The community of ground vegetation under A.excelsa plantation was more diverse and stable than the others. The ground vegetation under M. glauca, A.dammara and P.merkusii plantations were dominated by herbs, while under A. excelsa plantation were dominated by seedling of trees, that originated from A. excelsa stand and others surrounding tree species.

Testing of rice meal inoculum in the fields Suppl.Berita Biologi 3:1-5.With the aim of testing and using of inoculum by users, studies of the using of inoculum rice powder for oncom production have been carried out.The experiment utilized different kinds of inoculum which contained some strains of Neurospora spp., Mucor spp.,and Rhizopus spp.have been done at several places of oncom producers in Bandung and Bogor.The quality of products were evaluated by analyzing of organoleptic test, texture and growth of mold comparing with local oncom. The results obtained in the experimentshowed that product made by using one strain of Neurospora spp., more liked moderately and having good mold growth, finely conpact and soft texture comparing with the other products and local red oncom in Bandung and Bogor.Besides that all of the strains of Mucur spp., produced good quality of oncom comparing with local black oncom.But all of the strains of Rhizopus spp., did not capable making good quality cf oncom. About the utilizingof powder inoculum by users in general must be fuether more investigated.

(Leguminosae) has been observed at 10 flowering plants at Cibinong, Bogor. Observation were made at 6 a.m.-6 p.m. by means of collecting insects that visit the flowers of A. villosa for 30 minute with the interval time collection of 2 hours.There were found Hymenoptera (17 species), and followed by Lepidoptera (7 species) and Diptera (3 species).The community sturcture of the insect visitors at interval of 2 hours are varies, the number increased toward the mid day, and gradually declined in the evening. This fluctuation is probably due to the nectar content during the day.

Abstract

SUCIATMIH Y.INDIARTO.1987.Morphology of mycorrhizal fungi in grass roots.Suppl.Berita Biologi 3 : 26 - 30.Visual examination of roots of grass species collected from the surrounding of Herbarium Bogoriense building and Baranangsiang has shown that the main infecting organisme are Phycomycete endophytes of the vesicular arbuscular type.It was attempted to assess morphology of fungi in the grass roots.External mycelium displays dimorphism. There are thick walled asceptate hyphae and thin-walled septate External vesicles may be formed singly and are sometimes furnished with a rudimentary hyphae Root penetration takes place by hyphae entering either epidermal cells or root hairs.The internal mycelia in grasses correspond to descriptions of similar endophytes in other plants. Internal vesicles are formed mainly in the outer cortical cell layers.In general, these are located both in interaeellular and intercellular position.Internal arbuscules are usually developed in the inner cortical cells.Each cell becomes occupied by an arbuscule.
