Vol. 26, No. 1, 2009Indonesian Agricultural Research AbstractsAn experiment on increasing tomatoes quality in hydroponic culture was done in a plastic house ofAgriculture Faculty, UPN "Veteran", Yogyakarta. The experiment was a factorial experiment of twofactors, with five replications and arranged in randomized completely block design. The first factor wasnutrition formulation: Sundstrom (F1) and Excell (F2). The second factor was varieties of tomato:Bonanza (V1), Intan (V2) and Kaliurang 206 (V3). The aim of this research was to determine the effect ofthose treatments on quality of tomato in hydroponic culture. The result showed that the yield and qualityof Bonanza variety and Kaliurang 206 variety were improved, especially in fruit weight (1259.62 gram),fruit hardness and ascorbic acid content. The Sundstrom nutrition was the most appropriate for tomatohydroponic media, resulting in better quality, especially for fruit weight, number of fruits, fruit hardness,ascorbic acid content and sugar content.F02 PLANT PROPAGATION020 GUNADI, N.Growth and yield of 20 TPS (true potato seed) progenies in the highland of Pangalengan, West Java.Pertumbuhan dan hasil 20 progeni kentang asal biji botani di dataran tinggi Pangalengan, JawaBarat/Gunadi, N.

Seedling tuber of 20 new TPS progenies were grown in the experimental plots, which were arrangedin a randomized completely block design with 4 replications. The common cultivar of cv. Granola wasused as control. The results indicated that 4 progenies of AL-624 x TPS-67, CFK-69-1 x TPS-67, MF-II xC95LB-13.2, and MF-II x TPS-67 had higher tuber yields than those of other progenies. These 4progenies had comparable tuber yields per plant to that of cv. Granola. Two progenies of AL-624 x TPS-67 and CFK-69-1 x TPS-67 had also comparable tuber yields per ha to that of cv. Granola. The resultscould be used as a recommendation in order to select TPS progenies as alternative planting material inpotato production using TPS other than traditional seed tuber.021 KRISTINA, N.N.Shoots multiplication, rooting, and acclimatization of Gynura procumbens.

Acclimatization were performed on two kinds of media i.e. dung manure performed + soil (1 :1) or husk + soil (1 : 1). Rooting and shoots multiplication were arranged in completely randomizeddesign, with 10 replications and 2 explants for each bottle. Acclimatization was arranged in randomizedblockdesign with 10 replications and 1 plantlet for each treatment. The results showed the best mediumfor shoot multiplication was MS-free hormone with 5.4 shoots, 2 months after cultured. The highestnumber of roots was obtained in NAA 0.1 mg/l with 9.3/plantet. MS + IBA 0.3 mg/l give the longest roots(9.58 cm) and IAA 0.1 mg/l the highest number of leaf (12/plantet). Interaction between the source10
