Cereal breeding programs are interested in increasing the number of generations per year to reduce the time needed to develop new cultivars. A common method to accomplish this is to extend the photoperiod to speed up plant growth. For oat, this method is problematic because the species responds to changes in light and temperature. Current methods of fast generation cycling in oat require embryo rescue, which is labor intensive and has a low success rate. Recently a method was developed using increased photoperiod and foliar mineral supplement to reduce generation time for wheat and barley. We evaluated this newly published method in oat and found that anthesis occurred 15 ± 3 days faster, however there was a 3-fold reduction in seed count and a 2-fold reduction in inflorescence weight. In addition, we measured endogenous ascorbate to evaluate the physiological status of the plants under fast generation cycling conditions. For oat, fast generation cycling would be effective to more rapidly advance populations using single seed descent, but not as useful when seed yield is important.
The synthetic systemic acquired resistance elicitor benzothiadiazole (BTH) has been shown to elicit avenanthramide biosynthesis in the oat cultivar ‘Belle’. This report investigates the response of multiple oat cultivars to BTH as well as 2,6-dichloroisonicotinic acid (INA) at different growth stages. Oat seedlings (‘Gem’, ‘Kame’ and ‘Ogle’) were treated with 2,6-dichloroisonicotinic acid (INA) or benzothiadiazole (BTH) at the three leaf (Z13) stage and subsequently assessed for accumulation of avenanthramides and analyzed for the activities of hydroxycinnamoyl-CoA:hydroxyanthranilate N-hydroycinnamoyl transferase (HHT). In addition, four cultivars (‘Belle’, ‘Gem’, ‘Kame’, and ‘Ogle’) were treated at the Z43 stage with BTH. The results indicated that after 48 h avenanthramides accumulated to significantly higher levels in the oat leaves in response to both INA and BTH treatment and this response tended to be fairly long lasting (336 h or more). Both elicitors also raised the activities of HHT enzyme in seedling leaves after 48 h. Genotypic differences in the kinetics and quantitative response were also observed in both the seedlings and the mature plants. The magnitude of avenanthramide production in the leaves was somewhat higher in the more mature plants. Filling grain also showed higher levels of avenanthramides compared to the untreated controls.
