Influence of storage and package condition effects on seed germination of Matricaria chamomilla L

Matricaria chamomilla L. is an annual plant belongs to Asteraceae family, which has been used and cultivated globally as an antioxidant and anti inflammation. This project was carried out to determine the best treatment of seed moisture content and storage temperature to maintain maximum viability in addition to investigation impact of various coating package in seed storage. A factorial experiment was conducted in completely randomized design and rates of studied factors were 30, 60, 90, 120, 150 and 180 days for time; 5, 7, 9, 11 and 13% for seed moisture; 10, 15, 20 and 25°C for storage temperature, aluminum and nano cottage for package. Increasing storage time caused reduction in seeds viability under high temperature and moisture condition. Whereas, in nano package (NP) it was lesser compared to aluminum package (AP). NP had better performance in most temperature and moisture rates. Germination percent (GP) was 95% in moisture of 5 and 7%, 25°C and 30 days. This treatment had 1 percent reduction after 6 months which was not significant. It seems that low moisture neutralized negative effect of rising temperature. Moisture of 9%, 25 °C and 30 days led to 84% of GP in both packages which reduced to 55 and 51% after 6 months in NP and AP, respectively. It can be suggested that moisture of 5 and 7% under 10 °C and NP is the best condition for chamomile seeds storage which maintain seeds viability for long-term.
