Abstract

Garlic (Allium sativum L.) is included in the genus Allium sp., propagated vegetatively through clove. In plants that are propagated vegetative, viral systemic diseases will be carried over to the next generation. In conventional methods/ tissue culture techniques combined with size and heat treatment the explant material can used as virus elimination. The activity research conducted at the Balitsa tissue culture laboratory from April to July 2018. The purpose of the study was to see the effect of size, heat treatment of explant material on the growth and development of garlic variety Tawang Mangu. The treatments were (1) explant size E1 = 1/3 clove, E2 = shoot tip, E3 = meristem tissue, (2) heat treatment 37oC, T1 = without treatment, T2 = heat treatment for 2 weeks, T3 = heat treatment for 4 weeks, T4 = heat treatment 6 weeks. The composition of the growing media: MS + MS vits + sucrose 30 g/l + IAA 2 mg/l +Kinetin 2 mg/l + GA3 0.01 mg/l + Gel gro 2 g/l, pH 5.7. The results of the study (1) were visually observed that the smaller the size of the explants and the length of heat treatment, the lower the percentage of explants that grew normally. (2) Percentage of contamination 33.33 – 60% caused by bacteria or fungi. (3) The percentage of infected plantlet with virus with DAS ELISA technique were 40 – 66.67%.

Abstract

The expired status is addressed to the seeds that have exceeded the recommended planting period by the producer, while invigoration is the improving process of a vigor or performance of the deterioration seeds. The research purposes were to find out the best composition of kind and immersion time of a flora material extract that could improve physiological quality of the expired chili seeds. The research was conducted at the Seed Laboratory of Indonesian Vegetable Research Institute (IVEGRI), Lembang from Mei 2018 to December 2018 using a Completely Randomized Design (CRD) of 11 treatments which was repeated three times. The treatments consisted of: (1) Control (expired seeds without treatment); (2) Green coconut water 15% + Incubation 24 hours; (3) Ambon banana extract 15% + Incubation 24 hours; (4) Ambon banana extract 15% + Green coconut water 15% + Incubation 24 hours; (5) Cucumber extract 15% + Incubation 24 hours; (6) Green coconut water 15% + Incubation 48 hours; (7) Ambon banana extract 15% + Incubation 48 hours; (8) Ambon banana extract 15% + Green coconut water 15% + Incubation 48 hours; (9) Cucumber extract 15% + Incubation 48 hours; (10) Green coconut water 15% + Incubation 72 hours; (11) Ambon banana extract 15% + Incubation 72 hours. Then, the incubated seeds were germinated using top of paper (TP) method by the Copenhagen Tank apparatus. The results showed that the use of green coconut water 15% + incubation 24 hours (treatment No. 2) or cucumber extract 15% + incubation 48 hours (treatment No. 9) could improve viability and germination speed performance in range 12.67-13.33% and 3.85-5.10%/etmal respectively of the expired chili seeds with viability condition less than 75.00%.

Abstract

Seeds are one of the factors that support the success of plant cultivation. This study aims to obtain information on seed production of 17 shallot varieties in the highlands during the rainy season. Research was conducted to find out the production of shallot seeds in Indonesian Vegetable Research Institute (IVEGRI) Lembang (1,250 m above sea level) from October to December 2020. The material used is in the form of 17 varieties of shallot from the IVEGRI, namely: Sembrani, Katumi, Maja Cipanas, Bima Brebes, Kuning, Pikatan, Trisula, Pancasona, Mentes, Kramat 1, Kramat 2, TSS Agrihort 1, TSS Agrihort 2, Violetta 1 Agrihorti, Violetta 2 Agrihorti, Violetta 3 Agrihorti, Ambassador 1 Agrihorti. Wet weight, dry weight of askip and seed weight per plot (15.4 m2) obtained range from 26.9 kg -58.4 kg, 18.0 kg -36.5 kg, and 10.0 kg -26.3 kg. Violetta 2 Agrihorti is the variety that produces the highest wet weight per plot, and Sembrani is the variety that produces the dry weight of askip and the highest seed weight. The ratio between the weight of the seeds planted with the seeds produced in this rainy season planting ranges from 2.6 (Sembrani) – 11.0 times (Violetta 3 Agrihorti) on average 7.1 times. The production of onion seeds can be carried out in the rainy season and is influenced by the variety.
