Abstract

The research was conducted to study the effect of storage condition and osmoconditioning treatment on the viability of gmelina seed. The experiment was designed as a factorial experiment in a completely randomized design. The factors studied were storage condition (K), and osmoconditioning treatment (c). storage condition consist of room temperature condition (28-32oC) (K1) and under aircondition temperature (K2), where as osmoconditioning treatment consist of control (Co), PEG 0,4 MPa (C1), PEG 0,8 MPa (C2), KNO3 0,5 MPa (Ca3) and KNO3 0,1 MPa (C4). Observation was carried out in beweekly basis during sixteen weeks storage periods. The parameters observed were potential viability, growth strength vigour, and rate of metabolic activity changes. The research results showed the osmoconditioning treatment using PEG 0,4 and 0,8 MPa significantly increase total normal seedling. Moreover, osmoconditioning treatment using KNO3 0,5 MPa, and 1,0 MPa in the condition at under air conditioner room increase free fatty acid of the storage seed.

Abstract

Effectiveness of In Vitro Inhibitor Effects of Botanical Pesticides on Growth of Some Pepper Seed Born Pathogens ColoniesABSTRACT. Recently, the use of bio-pesticides significantly increases to control some plant diseases due to the drawback of chemical pesticides to environment. Some experiment have been done to evaluate the effectiveness of some vegetable oil as bio-pesticides to inhibit the colony growth of pepper seed born pathogens in vitro. Various concentrations of vegetable oil were added onto potato dextrose agar medium (PDA), afterward, the growth of pathogen colony in treatment was compared to control (medium without vegetable oil). Evaluation was done in certain period time depend on the growth of every pathogen colony Among the vegetable soil tested, clove oil and Andropogon nardus oil showed a very high inhibitory effect to colony growth of P. capsici, C. capsici, F. oxyporum, R solani, and S. rolfsii. Concentration 0.01% of those oil already inhibited the colony growth of all pathogens more than 75%, with the exception of A. nardus oil which required 0.03% to inhibit C. capsici colony. Concentration of clove and A. nardus oil above 0.01% completely inhibited growth of all pathogens colonies, except for F. oxyporum. Meanwhile, others vegetable oil like Curcuma xanthorrhiza, Kaempferia galangal, Kaempferia pandurata, and Curcuma domestica oil have a low inhibitory effect on growth of all pathogens colonies. To get inhibitory effect more than 75% on the growth of colonies, those vegetable oil needed concentration higher than 0.02%. However, K. galangal and C. domestica required 0.02% oil concentration for P. capsici and S. rolfsii, respectively.

Abstract

Persistence and Breaking Seed Dormancy of Land Rice CultivarsABSTRACT. Previous studies have been done to break seed dormancy in rice (Oryza sativa L.). However, since the behavior of seed dormancy are different for different varieties, there is a need to find effective methods for breaking dormancy in four most important cultivars of low land rice. Low land rice seeds were harvested at 95 days after planting (cv. Kalimutu and cv. Gajah Mungkur), 105 dap (cv. Way Rarem) or 115 dap (cv. Jatiluhur), and dried to 13% moisture content. The seeds were stored in an envelope paper at ambient temperature and relative humidity (28-310C, RH 81-89%) for up to 9 weeks with 1 week interval. Persistency of seed dormancy in each cultivar was determined based on the time needed to reach a minimum of 85% germination capacity. Various methods of breaking dormancy were applied: untreated control, soaking in water for 24 h, soaking in water for 48 h, soaking in 1% KN03 for 24 h, soaking in 1% KN03 for 48 h, soaking in 120 ppm GA3 for 24 h, soaking in 120 ppm GA3 for 48 h, heating 500C for 72 h, heating 500C for 48 h + heating in water for 24 h, heating 500C for 48 h + heating in water for 48 h, heating 500C for 48 h + heating in 1% KN03 for 24 h, heating 500C for 48 h + heating in 1% KN03 for 24 h, soaking in water for 24 h + in damp cloth for 24 h, mantriconditioning using sawdust and mantriconditioning using rice hull ash. Soon after the treatment the seeds were germinated, and seed viability and vigor were observed. Results of experiment showed the viability and vigor of low land rice seeds were increased after storage. Persistence of seed dormancy was different in each cultivar i.e. 3 weeks in Kalimutu (germination capacity 90%), 4 weeks in Way Rarem (87%), 6 weeks in Gajah Mungkur (92%), and 9 weeks in Jatiluhur (85%). Soaking the seeds in 1% KN03 for 48 h was the most effective method for breaking dormancy of Kalimutu, Gajah Mungkur and Way Rarem at harvest (0 weeks). Heating the seeds in a 500C oven for 48 h followed by soaking in water 24 h was the only effective method to break dormancy in cv. Jatiluhur at 2 weeks after harvest, while the time of harvest none of the method was effective.
