WebFeb 22, 2007 · First, the rate of intact Z1 mRNA decline was similar to the rate of dormancy relief during 9 months of afterripening. Second, cultivated oat ( A. sativa) grains (which are not dormant at maturity) contained much lower levels of these mRNAs than did highly dormant wild oat grains. WebDec 1, 1996 · A thermal after-ripening time model for dormancy loss accounting for seed moisture in the range 6-18% was developed and accurately predicted dormancy release for Wongan Hills seeds after- ripened under naturally fluctuating temperatures. 83 View 2 excerpts, cites methods and background
WebJan 6, 2011 · It is found that an afterripening requirement is a characteristic of the genus Crocus, and it can be fulfilled in nature during the Mediterranean dry summer, and for the … WebThe transition from the dormant to the non-dormant state of a viable and mature seed can take place at low hydration by exposure to air-dry storage conditions (dry afterripening; AR). The events occurring during this loss of dormancy are of considerable physiological, ecological and agricultural interest.
WebThe effects of low temperatures upon afterripening were studied. Dry storage at 5 C significantly retarded dormancy loss (Figure 2). Intact seeds germinated less than 5% after 3 months at 5 C compared with greater than 90% germination after 6 weeks at 20 or 30 C. However, afterripening did occur during prolonged storage at 5 C.

WebDrying, whether occurring naturally or imposed prematurely, results in the permanent suppression of transcription of most developmentally-related messages and, upon subsequent rehydration, the induction of those associated with germination and growth. From 30 to 50 d after pollination (DAP) the total RNA content declines in the developing …
