Dahlia ( Dahlia sp. ), a species of the Asteraceae family, is widely cultivated in China and exhibits seasonal blooming. The main challenges associated with this species are low cross-breeding efficiency and slow breeding. In this study, dahlia leaves and petals were employed as test materials to ascertain the optimal conditions for protoplast isol...

... of dahlia petal tissues by shredding, blocking, and crushing methods, the 248 number of protoplasts and their viability were counted after 4 h of enzyme digestion. The shredding 249 method yielded the highest number of protoplasts, at 3.67 × 10⁵ per millilitre, which was 2 to 11 times 250 higher than that of the crushing and blocking methods (Fig. 7a). The viability of dahlia protoplasts was 251 found to be greater than 80%, although the yield was lower at 2 and 4 hours. The viability was ...
