Abstract

The aim of this research was to examine the yield characters of peanut in drought stress. The experiment was conducted by using of peanut cv. Kelinci that is sensitive genotype as female parent and US 605 which is tolerant genotype as male parent, including the F2 population F1 offspring from hybrid cv. Kelinci (P1) with US 605 (P2). The number of pods, amount of filled pods, dry weight of pods, dry weight of seed, the number of seeds, are measured during harvest. Expression of all yield characters were influenced by genetic factor, except the variable weight of seed. All of yield show the quantitative and qualitative characters. The result analysis of Mendelians genetic yield showed all characters were controlled by 2 until 3 gene with the dominant and resesif epistasis combination pattern. Result from joint scalling test analysis showed all variable were not only determined by additive and dominant influence but also by genetic interaction. Additive influence with the high narrow sense heritability most of all variables together can give opportunity to obtain tolerant peanut line with heigh yield.

Abstract

Water stress due to drought is the most significant abiotic factor limiting crop growth and development. Drought stress inhibit germination and seedling growth, and extention of inhibition in germination under drought stress condition is varying in varieties. The previous research result showed that the differences in germination response under drought stress can be used as early test for screening to drought tolerance in plants. The objectives of this experiment were to evaluate the germination response of 36 soybean varieties under drought stress simulated by polyethylene glycol (PEG), to know the drought-stress tolerance level of 36 soybean varieties based on germination response in medium containing PEG, and to identify drought tolerant varieties. Soybean seeds were germinated in sand medium containing several PEG (6000) at concentration 0%, 15% and 20% which equivalent to 0, -0,41 and -0,67 MPa during 5 days. Germination responses were observed by calculating vigor index, germination percentage, lateral root number and measuring hypocotyl and root lenght and seedling dry weight. The level of drought stress tolerance of soybean varieties were evaluated based on index of reduction and drought sensitivity on germination variables in stres and non-stres conditions. The research result showed that drought stress on germination media simulated by PEG decreased vigor index, germination percentage, lateral root number, hypocotyl and root lengths and dry weight of seedling. The inhibition of germination increased with reduction of water potential. The water potential -0,41 MPa inhibited vigor index and hypocotyls length in all tested varieties, but inhibited germination percentage, lateral root number and dry weight of seedling in some varieties. However, decreasing of water potential -0,67 MPa inhibited almost germination variables in all varieties, except root length. Each tested soybean variety showed differences of germination response to drought stres. Varieties of Dieng, Tidar and Sibayak showed less inhibition than others, but Anjasmoro, Burangrang, Galunggung, Kipas Putih and Tambora showed more inhibition in seedling growth. Based on index of reduction and drought sensitivity on germination variables, Dieng and Tidar were identified as tolerant varieties, while sixteen varieties as medium tolerant and seventeen varieties as sensitive ones.

Abstract

Identification of nematode species is the first step in the resolution of major nematological problems. Accurate identification of maize cyst nematode species is essential for more detailed research, particularly for it control measure. Although morphological observations by using the key characters of each nematode are suitable for identification purposes, the cyst nematodes could not be clearly identified based on it due to the wide variations. For the identification of the cyst nematode species, key characters relating to body surface, head, mouth, esophagus, tail as well as habitat and feeding habits was used in the present examination. Procedures for the permanent and temporary preparations of nematodes were used. The nematode specimens were observed under the microscope to confirm the key characters. Results of measurements and descriptions revealed that the cyst nematode collected from maize roots in Madura island have the same ambifenestrate as that of Heterodera zeae. The underbridge is short and thin and there is two layer of bullae arrangement in vulval cone, the first layer with four finger-like bullae located immediately below the underbridge and the second layer very randomly located below the first one. These characteristics are of H. zeae. These complete of morphological identifications are a new report of H. zeae in Indonesia.

Abstract

Development and insecticidal activity of axenic infective juveniles (IJs) originating from endotokia matricida in maternal bodies of Steinernema glaseri and S. carpocapsae were investigated with a comparison to IJs developed in monoxenic culture. In comparison with the monoxenic steinernematids, the axenic ones grew slower and produced fewer IJs when they were cultured in a sterile chicken liver extract medium supplement with an autoclaved nematode infected Galleria mellonella larva. The phenomena of endotokia matricida, an intra-uterine development of hatched juvenile, occurred in an axenic culture as did the monoxenic ones. Although it occurred faster in monoxenic culture, the ratio of females bearing endotokia matricida was more numerous in axenic ones. These axenic females also produced IJs through the endotokia matricida phenomenon. Compared to the normal IJs develop in monoxenic culture, the IJs originated via endotokia matricida of axenic nematodes showed lower insecticidal activity and it could not reproduce in G. mellonella cadaver.

Abstract

Unequal understanding among tin mining stake holders on trade regulation often triggered social conflict and therefore it was suggested to build political will especially among national, provincial, and regencial/municipal government levels. One important effort to bring out political will is presenting an independent and scientific study on comparision between socio-economic and environmental impact of tin mining. Purposive sampling was conducted to inconventional miners at reserved forest at Lubuk Kelik hamlet, pepper farmers at Silip village, and rubber farmers at Bencah village. Tin mining changed soil properties and microclimate, reduced vegetation composition and structure, arbuscular mycorrhizal fungi, phosphate solubilizing microorganism, ants, and Collembola population. Land conversion increased and contributed up to 95% income. The welfare improvement, however, was apparent as the recovery cost was neglected by inconventional tin miners, and only pepper land conversion showed benefit. Inconventional tin mining regulation needs improvement in order to increase land use efficiency and recovery cost. Understanding on ecological balance of more people and for more sustainable social welfare should be improved as well.

Abstract

Flavan-3-ol is a secondary metabolite in tea plant that is used as anti obesity agent. The difficulty in obtaining Flavan-3-ol out of tea plant is due to dependency on season, need for large land, need for very intensive care and relatively low production. Therefore flavan 3-ol production needs tobe developed in vitro culture technique. This technique can cope with the handicapes above. It can effectively control production and requires less space. The purpose of this research was to enhance fl avan 3-ol production by modifyingmedium and precursor appropriately. The steps of this process were: (1) Callus induction through cultivating the tea shoot explants on medium fi lled with some growth hormone, (2) fl avan-3-ol induction on callus culture using Cu 2+ elicitor. (3) Observation over callus growth, (4) Observation over qualitative characterizes of flavan 3-ol. The result of the research using Cu 2+ elicitor shows that the production of flavan-3-ol increases by 12.5%.
