EFFECT OF DIFFERENT STORAGE MEDIA AND TEMPERATURES ON THE GERMINATION OF QUINOA (Chenopodium quinoa) SEEDS
Project no. 893 · Status: Kapanmış · 2018
Summary
An experiment was conducted to determine the effects of different storage media and storage temperature on the viability of quinoa seeds. Mature seeds have been collected from quinoa field in Izmir, Turkey in October 2017. Germination and emergence tests were conducted in factorial randomized complete block design using five storage media (cotton bag, paper bag, nylon bag, airtight plastic tube and vacuum) and four storage temperature (ambient, 16°C, 4°C, -24°C) as treatments. After conducting initial germination and emergence test, sample seeds were taken randomly from each storage media under different temperature and tested for germination at each four months interval since the time of seed collection. Emergence test was also conducted by sowing seeds in sand bed. Germination and emergence percentage data were recorded. There was statistical significant difference on the germination and emergence percentage of quinoa seeds due to storage media, storage temperature and their interactions. The germination percentage of the seeds reduced gradually with increasing storing period. After 24 months, the germination and emergence of the seeds was found to be below 70%. Statistically highest germination and emergence percentage were observed for seeds stored in plastic tubes under -24°C followed by nylon bags and vacuum bags the same temperature, and, the minimum values were recorded for seeds stored in cotton bags under ambient temperature. It was concluded that storing quinoa seeds for not more than 24 months in airtight (hermetic) plastic tubes under -24°C is better in maintaining the viability of the seeds.
