Popis: | The concentration of all fatty acids decreases during abscission in balsam fir, though saturated fatty acids decrease the least. The ratio of saturated:unsaturated fatty acids is strongly correlated with abscission. Postharvest needle abscission is a huge challenge in the balsam fir Christmas tree and greenery industry. It was hypothesized that lipid and fatty acid changes postharvest are linked to needle abscission. Branches were cut, hydrated in the lab to determine needle loss and water uptake. Other branches were sampled weekly for membrane injury, and lipid and fatty acids (FA). Total polar lipid and fatty acids decreased significantly (p |
