Abstract

There are 525 native palm species to Indonesia.Chromosome numbers of 61 Indonesian palm species have been reported,unfortunately, not all species were presented by their karyotype. Re-observation of palm chromosomes is needed, because mis identification of particular species and uncorrect chromosome counts might be happen in the past. Chromosome characteristics of some families, such as Poaceae and Onagraceae were proved useful for classification.On palms, almost all species within similar genera were known had similar chromosome numbers and different in chromosome forms and sizes.Trends to employ chromosome characteristics for palm classification is possible.Since, chromosome information on palm is limited,chromosome research has great challenge to do in the future.

Abstract

The upper respiratory tract is lined with ciliated epithelium or brush border that functions as the primary filter to the respiratory tissue. Epithelial trauma caused by neonatal bordetellosis serves as the predisposing factor for other respiratory diseases in growing pig. The aim of this research was to evaluate the effectiveness life nonpathogenic Bordetella Bronchiseptica vaccine that used in sucking piglets in Indonesia, to prevent the damage of ciliated epithelium. Twenty four sucking piglets 2 to 3 day-old were divided into treatment group containing fourteen and nontreatment group containing ten. Each sucking piglet of treatment group was vaccinated with life nonpathogenic Bordetella Bronchiseptica vaccine by intra nasal with 0.5 ml/nostril dose containing more than72.0xl0 CFU/ml bacteria. Three weeks post vaccination 10 of those treatment group and 6 from nontreatment group were challenged against local isolate B. bronchiseptica BS9 (BCC2455) toxigenic with 4.2xlO'CFU/ml dose. The clinical signs, reisolation of bacteria, and histopathological changes were observed. The result showed that 3 of 10, 5 of 6, 0 of 4, and 3 of 4 treatment and challenge sucking piglet group, nontreatment and challenge sucking piglet group, treatment and not challenge sucking piglet group,and nontreatment and not challenge sucking piglet group were found lost of cilia from most of the ciliated epithelial cells of nasal mucosa respectively. Three of 10, 4 of 6, 1 of 4, and 4 of 4 treatment and challenge sucking piglet group, nontreatment and challenge sucking piglet group, treatment and not challenge sucking piglet group, and nontreatment and not challenge sucking piglet group were found epithelial cells desquamation of nasal mucosa respectively. The results indicated that life nonpathogenic Bordetella Bronchiseptica vaccine could give 70 % protection against infection of B. bronchiseptica local isolate BS9 (BCC245) toxigenic infection and 75% wild type isolate present at the farm used for this research.

Abstract

The successfull cultivation of useful plant largely depends on the quality of seeds, especially viability and germination vigor. Seed of Picrasma javanica Blume has potential use in the development of templates for new drugs, e. g. to treat malaria.For most species there is still little or no information about the suitable temperature regime for germination and seedling depelopment,therefore,it is interesting to study germination and seedling vigor of Picrasma javanica. The mature green were picked and cleaned before using for experiments.Germination was carried out in 24 compartments of a thermogradientbar apparatus.The temperature gradient extends from 4.8 to 41.6°C with 1.6°C steps from the first to the 24 th compartment. Twenty seeds were germinated in each compartment. Seeds were sown on 2 layers of filter-paper strips.Everyday for 77 days during germination the germinating seeds were recorded.For hilling experiments those seeds from compartment number 3 to number 13 of thermogradientbar apparatus were than removed to incubator 32°C for 28 days. On the seedling vigor, all germinating seed from incubator were removed for replanting in growth room with sand medium. The seedling establishment capacity in the different thermal regions can thus be identified. The results showed that seeds attained 50% germination after 43 days when placed at the gradientbar 22.4°C to 41.6°C with optimum temperature 36.8°C. A 28 days temperatuture pretreatment ranging gradually from 4.8°C up to 20.8°C has promoted germination significantly. Mechanism of pretreatment on low and high temperature was discussed.

Abstract

Eight pollination treatments were executed on Talinum triangulare Willd. to observe alternative pollination systems and its effect on some flower activities and seed setting. The treatments can be grouped to autogamy and allogamy or geitonogamy.Flowers simultaneously were treated by the eight treatments day by day for two weeks in a month with three replications.Parameters observed were fruit set, anthesis duration, seed number per capsule and presence of stigmatic curvature. The result showed that the plant species was evidently flexible in pollination systems but the plant was outcrossing species with highest seed number (58.73 ± 5.95) per capsule and did not show stigmatic lobe curvature. The second and the third highest seed number per capsule were given by natural pollination with or without anther removal and with or without artificial polination (50.5 ± 2,87 and 49.0 ± 1) and this treatments also did not showed stigmatic lobe curvature. Articial pollination with or without flower bagging, withor without anther removal and with or without natural pollination generally gave lower seed number per capsule 40.67 ± 5.69,32.67 ± 10.95, 43.67 ± 9.5) except spontan autogamy(49.29 ± 10.14) and some of this treatments showed sigmatic lobe curvature.Stigmatic lobe curvature, therefore, was occured when no pollen occupation on it until prior to naturally flower reclose. Flower would be abscised when no artificial or natural pollination was happened but its stigma was curved before shed. Primary pollination mechanism in the plant was cross polllination (allogamy) but the plant is enough flexible in pollination systems. Autogamy especially spontan autogamy seem to be alternative pollination mechanism when no natural polinator visit.

Abstract

In order to know the effect of isolation method on the occurrence and capability of soil fungi to degrade cellulose,a study was conducted in postburning forest in Wanariset-Semboja, East Kalimantan. Soil fungi were isolated using three isolation methods:incubation at 45° C, treatment with 50 % ethanol for 15 minutes, and heat treatment at 70° C for 15 minutes.Plates for heat incubation and for other methods were incubated at 45° C and 27° C for three days, respectively. Cellulose degradation test of isolated fungi was examined using Carboxy Methyl Cellulose (CMC) media. Results showed that isolation method affected diversity and population of soil fungi. Heat treatment at 70° C for 15 minutes appeared to have highest diversity and population of soil fungi. Eupenicillium Javanicum var javanicum (van Veyma) Stolk & Scott, Talaromyces byssoclamydoides Stolk & Samson, T. flavus(Klocker) Stolk & Samson, T. stipitatus C.R. Benjamin, and Penicillium argillaceum Stolk et al. were dominant in postburning forest in Wanariset-Semboja, East Kalimantan. Twenty-one isolated fungi degraded cellulose.
