| Abstract | ||
| The prediction of seed viability is important for seed producers, and its prediction in storage depends on the understanding of the quantitative relationships between seed loss, seed moisture and storage temperature. In order to study the effect of temperature, seed and time on the deterioration of the anise seed, and also quantitative characterization of this effect and determining the coefficients of life, this study was carried out in a randomized complete block design in a factorial experiment in the Agricultural Laboratory of Tehran University. The temperature was measured at 4 levels (5, 15, 25 and 35 o C), soil moisture contents in 4 levels (5, 9, 13 and 17%) and six times (one, two, three, four, five and six months) as the factors were this test. The results of analysis of variance showed that the effect of temperature on seed moisture content was significant for germination indices at 1% level. With increasing temperature and humidity, germination declined over time. Life coefficients after six months of storage showed that survival curves can be plotted with a single source. Also, the results showed that by increasing the moisture content at any temperature, especially at higher temperatures, the life expectancy decreases with increasing moisture content. Using the life-time equation, the coefficients KE=4/21, CW =1-66, CH =0 038/0 and CQ =0,00039 were calculated. | ||
