Jurnal Sains Dasar Vol 3, No 1 (2014): April 2014
Publisher : Faculty of Mathematics and Natural Science, Universitas Negeri Yogyakarta

This research aims to know the influence of chili’s seed priming on improving germination, growth, and development in the field, before, during, and after stress conditions (water stress and disease). Priming is a technique of seed pretreatment with osmoticum solution or moist solids, which allows slow inbibition; thus radicals emergence and growth are prevented. It is a simple and easy technique to apply, which can increase the germination, and performance or vigour in a broad spectrum. Implementation is in three trials, each trial consisting of 2 stages. The first stage on the early experiment was priming (priming treatment with 4 days incubation and priming test), and the second stage was the germination (germinating the seed that has been treated by priming and germination test). The first stage on the further experiment is priming and the second stage were growth and development test before, during, and after the stress conditions. The results showed that seed priming treatments can maintain and improve the quality of seeds, and increase germination, both germination percentage and germination rate, as well as enhance the growth of plant height and total leaves of Chili at age 2 wat (weeks after transplanting). Key word: priming technique, disease, water stress, plant resistance

Publisher : Faculty of Mathematics and Natural Science, Universitas Negeri Yogyakarta

This research aims to to know the seed viability of the two dates on the market. It has been done from July to November 2014, in the laboratory of Mathematics and Natural Science Faculty, Yogyakarta State University. The type of Dates seeds are Sayer (oval-cilindrical, ±3cm, dark orange brown/more light than another), and Lulu (round, ±2cm, dark maroon reddish /more dark than Sayer’s). Viability test by germination testing; conducted on plastic tray with cotton sheet and fabric covered; fill with 100 grains of seeds. Repeated 4 times. Incubation at room temperature (±30oC). The parameters were seed fresh weight, seed dry weight, seed moisture, germination percentage and germination rate. The results were analyzed by compare mean - independent samples t test of SPSS 18’th. The results showed that the viability of both of Date’s seeds from local’s market (Sayer and Lulu) is high. Sayer’s have better viability than Lulu’s (due to the germination percentage and germination rate). Keywords: date seed, viability test, germination test
