甘藍與結球白菜貯藏試驗

Abstract

「初秋」甘藍與「煙台」結球白菜各以厚0.03m / m 之PE袋包裝，進行長期冷藏試臉。發現PE袋包裝可以減輕二者葉片黃化、離層形成、莖部纖維化及苞葉軟鬆等品質劣變現象；袋內添加乙烯吸收劑，除更可減輕上述品質劣變外，能有效抑制甘藍黑心（Tip burn）生理病的發生，但不能抑制結球白菜的黑心病。後者發現與二氧化碳農度過高（> 5%）有關。 'Chu-chiuo' cabbage and 'Ien-tai' Chinese cabbage were packed in 0.03m/m thick polyethylene (PE) bag for 2-5 month storage. KM(subscript n)O4 on vermiculite as ethylene absorbent inhibited the quality deteriorations of cabbage as leaf yellowing, stem fiberization and sprouting, head intumescence and physiological disorder of tip burn, however, disorder of black leaf speck was not alleviated. Disorder of tip burn was seriously appeared in the treatment without ethylene absorbent after 3-month storage. Packaging with ethylene absorbent kept cabbage in freshness for 5 months compared with the mere acceptable condition in perforate package for 3 months.
