| 英文摘要 | The effect of stratification on dormancy release of grape seeds crossing from the sub- to the supraoptimal range of temperatures and water contents was analysed by modified threshold models. the stratification impacted on dormancy release in three different ways: (i) dormancy was consistently released with prolonged stratification time when stratified at temperatures of < 15 degrees c; (ii) at 15 degrees c and 20 degrees c, the stratification effect initially increased, and then decreased with extended time; and (iii) stratification at 25 degrees c only reduced germinable seeds. these behaviours indicated that stratification could not only release primary dormancy but also induce secondary dormancy in grape seed. the rate of dormancy release changed linearly in two phases, while induction increased exponentially with increasing temperature. the thermal time approaches effectively quantified dormancy release only at suboptimal temperature, but a quantitative method to integrate the occurrence of dormancy release and induction at the same time could describe it well at either sub- or supraoptimal temperatures. the regression with the percentage of germinable seeds versus stratification temperature or water content within both the sub- and supraoptimal range revealed how the optimal temperature (t-so) and water content (w-so) for stratification changed. the t-so moved from 10.6 degrees c to 5.3 degrees c with prolonged time, while w-so declined from > 0.40 g h2o g dw-1 at 5 degrees c to similar to 0.23 g h2o g dw-1 at 30 degrees c. dormancy release in grape seeds can occur across a very wide range of conditions, which has important implications for their ability to adapt to a changeable environment in the wild. |
