Abstract

ABSTRACTBasil (Ocimum basilicum L.) is cultivated in many countries as vegetable crop, and as herbal medicine or pesticide for mosquito larvae, but there is limited information on its seed viability. Three experiments were conducted at Seed Science and Technology Laboratory Departement of Agronomy and Horticulture IPB from January to June 2011. Experiment one tested viability of basil seeds with different maturation obtained from different fruit maturity and drying treatment. Experiment two stored basil seed for 12 weeks in ambient condition and tested seed viability weekly. In experiment three, two seed lots that have been stored for 2 and 14 weeks in ambient condition were invigorated with GA3 1,000 ppm and KH2PO4 1.5% and light treatment 820 lux m-2. It was revealed that basil seed was physiologically mature at 44-49 days after flowering with 12.5% moisture content and low viability of 34.0%. After-ripening period of basil seed was two week where the seed viabilty increase to 56.7%. Seed viability did not significantly change during 12 weeks stored in ambient condition. Maximum viability of basil seed (64.34-66.52%) could be achieved by invigoration treatment  with GA3 1,000 ppm and light treatment 820 lux m-2.Keywords: dormancy, germination, seed maturity, vegetable crop

Abstract

Nutmeg is an Indonesian native plant, produces essential oill as an export commodity. However, it has low seed uniformity that mengurangi keseragaman tanaman di lapang. The main objective of this research was to obtain morphological characteritics as parameter for nutmeg mother plants selection. This field research was carried out from August-December 2014 at Toisapu, Wakal and Lula nutmeg seed source plantations in Ambon, and Seed Storage and Testing Laboratory, IPB. Characterization was undertaken on ten mother plants from each  Wakal and Lula seed source plantations and eight mother plants from Toisapu seed source plantation. Quantitative and qualitative characters of vegetative, fruit, mace and seed from every mother plants were analyzed with  Gower’s similarity test. Mother plants that produced high uniformity seed was the 7th (0.80), the 8th (0.93) and the 10th (0.80) mother plants in Wakal; the 2nd (0.80) mother plant in Toisapu; the  2nd (0.82), the 5th (0.80), the 6th (0.82), the 8th (0.84), the 9th (0.80) and the 10th (0.93)  mother plants in Lula. Those selected mother plants produced morphological uniform seed morphologically. Lula seed plantation had the highest uniformity level among mother plants (0.77-0.87) compared to Toisapu (0.70-0.87) and Wakal (0.69-0.84) mother plants. The morphological characteristic can be use to select the source seed mother plants which able to produce high morphological uniformity seeds.Keywords: Gower’s similarity, seed production, uniformity
