The experiment was aimed to study the effect of hydrogen cynamide on tea growth and production after pruning. The experiment was conducted at Goalpara Tea Plantation (1100 m above sea levels) from September 1994 to March 1995. Clone TR12025 planted in 1976 with 29 months pruning cycle was pruned a week before application of hydrogen cynamide. Randomized Complete Block Design was used in this experiment with four treatments and four replications. Treatments consist of hydrogen cynamide 0.00 % (control), 0.50 %, 1.25 % and 2.50 %. An experiment unit consists of 20 tea plants. The results showed that treatments of hydrogen cynamide was not significantly increase the number of shoots and weight of "tipping" (shoot tipped on first plucking). The production was not significantly increased by the treatments. However, hydrogen cynamide at 0.50 % could increase 11.5 % fresh weight (equivalent 0f 9.9 % dry weight).

In this experiment. the changes on leaf osmotic potential and accumulation of proline and abscisic acid were identified from drought-tolerant and drought - sensitive soybean genotypes. Three drought - tolerant (Mlg 2805, Mlg 2984 and Mlg 2999) and two sensitive soybean genotypes (Mlg 2510 and Mlg 3541) were subjected to drought condition created by regulating water supply in greenhouse. The results revealed that exposing plants to drought stress brought about a decrease of leaf osmotic potential. The decrease of which was greater in drought-tolerant genotypes (6.91 to 10.11 bars) than in sensitive genotypes (0.55 to 0.69 bars). The decreasing of leaf osmotic potential was followed with increasing praline accumulation, especialy for Mlg 2805. Only Mlg 2805 showed the significant ABA accumulation when the plants were subjected to drought stress. It is suggested that the drought tolerance was associated with the reduction of leaf osmotic potential (osmotic adjusment) in which proline might play an important role. The role of ABA could not be clarified since there had been a great variability in ABA content of all tolerant genotypes.

Two sets of experiments were conducted to determine the effect of growth hormones, argynine, and coconut water, on the adventitious shoot induction from garlic tissue, and also to find out the best medium for adventitious shoots proliferation. Both experiments could induce direct adventitious shoot and indirect adventitious shoot formation, from calli. Medium with 2 ppm Kinetin and 0.4ppm 2,4-Dproduce good quantity and quality of shoots. The number of shoot from this medium were 32.6 shoots per explant. Medium with 0.5 ppm Kinetin, 0.1 ppm 2.4-D, 25 ppm Argynine, and 10% coconut water produce the highest diameter and good quality of calli, while medium with 1 ppm 2iP and 25 ppm Argynine induced adventitious shoot from calli and produced the highest number of shoot per culture (33.9 shoots).

The objective of the experiment was to find out if sterilization of the media prior to planting, combined with application of various rates of chicken manure for fertilization, would increase production of calla lily tubers with are 3 - 5 cm diameter size. The experiments used two plots, one with sterilized and the other with non-sterilized media and chicken manure. Small tubers with ± 1 cm diameter and had fulfilled their dormancy requirement were planted. Chicken manure was applied at four different rates: 3, 5, 7, 9 kg/m2, and replicated four times. Data were taken on height, fresh and dry weight of plants, number of leaves. and percentages of various tuber size, following harvest. Tubers showed better results in terms of fresh and dry weight, and percentages of larger than 3 cm diameters tubers. Highest yields were obtained with 3 kg/m2 chicken manure.

The experiment was aimed to study the effect of number of lungs and leaves at lung to growth of shoots and first time harvest at lung pruning of height land tea (Camellia sinensis). The experiment carried out at Gedeh Tea Plantation, PTPN XII, Cianjur, West Java, from December 1993 to March 1994. In this case we used tea Clone TRI 2025. The experiment was arranged in Randomized Block Design with 3 replications. The first factor, number of lungs, consisted of 3 different level : 2, 3, 4 lungs per tea. The second factor, number of leaves at lung, consisted of 3 different levels : 25, 50, and 75 leaves per lung. The Experiment showed that number of shoots and first time harvest affected by number of lungs, but number of lungs didn't affect to height of shoot, percentage of banji, wet weight shoots on tipping and first pluck production were not affected. The tea with 4 lungs had significantly greater number of shoots than 2 or 3 lungs. The earliest first harvest time was achieved by 2 lungs tea (3 to 9 days earlier), but was significant with 3 lungs tea.

Polyamines have been reported to have a role in habiting senescene. Polyamine application inhibited fruit softening and extend fruit shelflife. The common polyamine included putrescine, spermidine, and spermine. The objective of the present study was to determine the effect of concentration and length putrescine application on some quality changes in banana. The result showed that putrescine had some effects on weight loss, inhibited fruit softening, and color development. However, the effect were not consistent. The best concentration and length of application could not determine. It was suggested that pressure infiltration was used for polyamine application

Field experiment for soybean seed production was carried out in Darmaga Experimental Station from June to September 1992. Three varieties of soybean, namely Lokon, Wilis, and Amerikana (early, middle, and late maturity, respectively) were planted both by saturated and conventional soil culture. Seed quality testing was carried out in the Laboratory of Seed science and Technology at IPB, Bogor, from September to October 1992. Yield components and seed production of the three varieties showed the same pattern in both saturated and conventional soil culture. Seed quality of Lokon and Wilis varietieswere higher than that of Amerikana in both cultivations. This was due to the less field weathering experienced by Lokon and Wilis varieties. Compared to the conventional soil culture, the saturated soil culture improved the yield components, seed production, and performance of seed physical and physiological quality of the three varieties.
