This study aims to identify and determine the viability and vigor of seeds of some species of plants in Ambon city market. This research was conducted in the Laboratory of Seed Control and Certification Institute (BPSB) Passo and at the Faculty of Agriculture, University of Pattimura Greenhouse Ambon from February to April 2012. The method used was testing seed with duplo system and using T test with three replications. There were eight seed plant types tested, i.e corn, mustard, long bean, eggplant, bitter melon, cucumber, large chili, and cabbage. Responses observed consisted of viability parameters, i.e. germination percentage, germination rate, and germination rate index, and vigor parameters consisted of simultaneity sprouted seeds and sprouted seeds pace. The results showed that seeds in the market city of Ambon, such as corn, mustard, long beans, eggplant, bitter melon, cucumber, large chili, and cabbage were in excellent quality, as shown by the results of the seed germination rate which reached 90.33 - 97.33% at laboratory test, meanwhile at greenhouse test the rate reached 90.33 - 94.33%, strong vigor with synchrony seed grow were 51.00 - 64.67%, and the growth rate reached 29.46 - 33.65%.
This study was aimed to determine the proper dose of ash desiccant on maize seed stored for 30, 60 and 90 days. The design used was a Completely Randomized Factorial Design, with two factors and three replications. The first factor was desiccant dose (D) : Do = 0 % (control), D1 = 5 % (12.5 g of seed weight), D2 = 10% (25 g of seed weight), D3 = 15 % (37 g of seed weight), D4 = 20 % (50 %g of seed weight), D5 = 25 % (62.5 g of seed weight). The second factor was length of storage (S) : S1 = 30 day storage, S2 = 60 day storage and S3 = 90 day storage. The result show that use of desiccant only gave effect on the water content of seeds (12.31 %) and speed of seed growth vigor parameters (24.84 %). Use of desiccant in 90 day storage were able to maintain water content of seeds (12.43 %), seed germination viability parameter (100 %), and vigor of seeds, which consisted of seed growth simultaneity (66.77 %) and seed growth speed (28.71 %). The interaction between the use off ash desiccant and the length of storage had no effect on viability and vigor of maize (Zea mays L) seeds but had an effect on their water content after storage (12.73%).
This study aimed to determine the best level of phosphate basic fertilization for seed production of Hulaliu corn varieties with high viability and vigor. This study was conducted in two places, namely in Booi Village, Saparua Subdistrict, Central Maluku District, for experiment with phosphate fertilization treatment, and in the Laboratory of Balai Besar Perbenihan dan Proteksi Tanaman Perkebunan Maluku in Passo, Baguala Subdistrict, Ambon, for testing seed viability and vigor. The experimental design used was a single factor Randomized Block Design with five levels of phosphate fertilization, consisting of P1 = 50 kg P2O5 per ha; P2 = 55 kg P2O5 per ha;. P3 = 60 kg P2O5 per ha; P4 = 65 kg P2O5 per ha, P5 = 70 kg P2O5 per ha = 70 kg, and with three replications. The results showed that the optimal levels of phosphate fertilization to enhance seed viability and vigor of Hulaliu local corn varieties were between 55 to 70 kg P2O5 per ha.
Indonesia is the centre of origin and distribution of durian plants globally, so it has a high genetic diversity of durian plants. Durian propagation can be done vegetatively through grafting. The success of durian grafting is primarily determined by many factors, one of which is the grafting position. This study aimed to examine the best grafting positions on the success rate of grafting of local durian (Durio zibethinus L.) from Maluku. The research was carried out in a nursery located in Telaga Kodok hamlet, Hitulama Village, Leihitu District, Central Maluku Regency, which lasted for six months, namely from December 2021-February 2022. The study was in an experimental form using a randomized block design (RAK) 1 factor with five repetitions. The factor being tested is the position of the grafting, which consists of 5 levels: grafting on the stem hump, grafting 10 cm, 15 cm, 20 cm, and 25 cm above ground level. The study's results obtained information that the grafting position treatment had a significant effect on the percentage of success and the increase in the number of leaves at the end of the observation. The highest rate of grafting success in the study was found in the treatment of the grafting position on the stem stump, which resulted in a success percentage of 98%.
