The objective of the experiment was to determine the effect of coating materials and storage temperatures in inhibiting the ripening process of banana fruits. The experiment consisted of two factors namely storage temperatures (ambient and cool) and coating materials (control, Carnauba wax, bee wax, and Sempefresh). One experimental unit consisted of two fingers of banana. The experiment was replicated three times. Observation was conducted on the following variables: peel color development, weight loss, fruit softening, ratio of flesh and peel weight, sugar content, and titratable acidity. Result of the experiment showed that carnauba wax 6 % inhibited weight loss, fruit softening, and the increase of flesh and peel weight ratio. Bee wax inhibited fruit softening, peel color development and sugar content. Fruit treated with carnauba wax 6 % could be stored at cool temperature for 25.9 days, 10.5 days longer than untreated fruit stored at ambient temperature. Among the three coating materials, Sempefresh had the lowest effectiveness in inhibiting bananaf ruit ripening process. Key words: Coating, Ripening, Banana, Shelf life

A study to obtain a method of rapid clonal propagation of bananas was done. The investigated cultivars were Pisang Mas (AA), Pisang Ambon Kuning (AAA), Pisang Barangan (AAA), and Pisang Rajabulu (AAB). The basal medium was MS, the treatment were IAA (0 - 4.5 mg/l) and BAP (0 - 10.5m g/l), and the explants were suckers from the field. The experiment was designed with Randomized complete design, and repeated in 10 bottles for each treatment. The result of experiment showed that IAA alone significantly induced shoot multiplication. The role of IAA could be replaced by BAP. Cultivars, IAA and BAP interacted each other to induce shoot multiplication. The best treatment to induce shoot multiplication was the combination of IAA and BAP, and the concentration depend on the cultivar. After 8 weeks, the highest number of axilar shoots (12.6 shoots/bottles)w as obtained by Pisang Ambon (AAA), followed by Pisang Mas (AA) 8.2 shoot/bottle, Pisang Barangan (AAA) 7.8 shoot/bottle, and Pisang Rajabulu (AAB) 7.6 shoot/bottle.

The study was conducted to find out some factors affecting low disease intensity and slow diseased development on several traditional rice through i.e. a) regeneration ability afterwards pathogen invation, b) to drive on sclerotium formation on traditional rice straw (i.e. Bayar pahit. Bayar palas. Karang dukuh, Lemo. Pandak) and improve variety (IR 36) in the moisture chamber, and also in water agar + rice sheath extract, c) the difference of internode and sheath long. The result revealed that some traditional rice (Bayar pahit, Bayar palas, Karang dukuh, Lemo and Pandak) possesa good regeneration ability afterward rice hills damaged by a pathogen invation. Pathogen also faided to produce sclerotium on Bayar pahit, Bayar palas, Karang dukuh and Lemo, and it was more due to the lack of available nutrition for pathogen fisiological prosses in the several traditional varieties. It was also possibly has inhibitor chemical compounds that inhibit sclerotium formation. There was known that stem internode was longer than sheath. So the pathogen could not reach to uppers heath. Diseased development was really slow on the traditional varieties that had three characteristics mentioned above. Key word: Rice, Sheath blight, Tidal swamp

The research was conducted at Seed Science and Technology Field Experimental and Laboratory, Faculty of Agriculture, Bogor Agricultural University since January until July 1998. Randomized Block Design was used in this experiment which consist of two factors and three I replications. The first factors were row spacing 60 cm x 25 cm (J1) and 60 cm x 45 cm (J2) and the second factors were application of 100 ml paclobutrazol/plant with concentration 0 ppm (P1), 125 ppm (P2), 250 ppm (P3) and 500 ppm (P4). The plant height was increased at narrow spacing especially at 0 ppm paclobutrazol. Paclobutrazol application reduced plant height, increased stem diameter and it's caused minimal lodging at generatif period. The highest seed production per plot was resulted at 60 cm x 25 cm with 250 ppm and 500 ppm of paclobutrazol (146 % and 155 % as compared with control treatment), and the highest seed production per plant showed at 60 cm x 45 cm and 60 cm x 25 cm with 500 ppm of paclobutrazol (197 % and 198 % compared with control treatment). Paclobutrazol125 ppm, 250 ppm, and 500 ppm increased flower diameter, number seed per flower, 1000 seed weight, germination capacity, and seed vigour. The optimum combination of treatment was showed at 60 cm x 25 cm and 250 ppm of paclobutrazol.

Tm-2 adalah gen yang mengendalikan ketahanan terhadap tomato mosaic virus (ToMV) pada tomat (Lycopersicon esculentum) dan berasal dari Lycopersicon peruvianum. Pada penelitian ini digunakan dua galur tomat yang mempunyai latar belakang genetik yang sarna GCR26 dan GCR3 6, akan tetapi keduanya dapat dibedakan oleh adanya gen Tm-2 pada GCR36. Melalui analisis random amplified-polymorphic DNA (RAPD) terhadap dua galur tomat tersebut di atas diketahui adanya primer RAPD yang menghasilkan fragmen spesifik untuk GCR236. Selanjutnya fragmen tersebut sekuennya dianalisis, dan dari hasil analisis sekuen tersebut dibuat sepasang primer sequence characterized amplified region (SCAR) Yang merupakan marka DNA kodominan yang bisa membedakan baik genotipe homozigot gen Tm-2. Oleh karena fragmen dihasilkan terkait dengan Tm-2, maka primer SCAR tersebut merupakan sarana yang dapat digunakan untuk pemulian tanarnan tomat bagi pembentukan varietas tahan virus.
