Abstract
Seed viability is one of the most important physiological quality benchmarks of seeds. The use of appropriate germination media can affect the results of seed viability testing. This study aims to determine the optimal germination media in tobacco seed viability testing. This research was conducted at the Seed Laboratory of the Indonesian Sweetener and Fiber Crops Research Institute, Malang in January - March 2019. The research method used a two-factorial randomized block design (RAK). The first factor is tobacco seed varieties consisting of Kasturi in 2007, Bojonegoro in 2012 and Kemloko in 2014. The second factor is the seed germination media consisting of straw paper, cotton, towel tissue, paperboard and newspaper. The results showed that the Kemloko variety of tobacco seeds germinated in the towel tissue had the best seed vigor and viability percentage. Seed germination media with paperboard, towel tissue and straw paper can be used to test the viability of tobacco seeds because they have a percentage of simultaneous growth, percentage of the growth speed, percentage of germination, percentage of the growth potential maximum and normal seedling dry weight which are equally well
Highlights
One of the leading commodities of smallholder plantations in East Java Province is tobacco (Nicotiana tabaccum L)
Seed viability testing is carried out to determine the physiological quality of seeds using appropriate germination media
The Tobacco Plant (Nicotiana tabacum Linn.) Is a plant native to the American continent and entered Indonesia about 400 years ago, so it has long adapted to the diverse growing
Summary
One of the leading commodities of smallholder plantations in East Java Province is tobacco (Nicotiana tabaccum L). Seed viability testing is carried out to determine the physiological quality of seeds using appropriate germination media. Testing viability of seeds such as germination requires optimum conditions on germination media, temperature and humidity. The results of the Setiarini (2010) study showed that the pre-germination treatment for watermelon without seeds cultivar New Lucky is to moisten the seeds with water on paper straws for 2 days, plant them on sand media or mix soil, sand and compost (3: 2: 1). According to Agustin and Lestari (2016) that germination media using flannelette, newsprint, samson paper, towel tissue, cotton, stencil paper, rock wool and filter paper are suitable for use in the viability test of lettuce and onion seeds. Research on appropriate germination media, especially paper substrates, is needed to obtain optimal test results on tobacco seeds. This study aims to determine the optimal germination media in testing the viability of tobacco seeds
