Effect of pyrazinamide and salicylic acid on the storage quality of Chinese toon bud after harvest
In order to prolong the storage period of Chinese toon bud and improve the quality of postharvest Chinese toon,we used Chinese toon bud as raw materials and the endogenous hormones salicylic acid and pyrazinamide as entry points.The toon bud samples were treated with 100 μmol/L pyrazinamide for 20 min,50 µmol/L salicylic acid for 10 min,and 100 μmol/L pyrazinamide for 20 min followed by 50 μmol/L salicylic acid for 10 min,respectively.The morphologic changes of Chinese toon bud on the 1st,3rd,5th and 7th days of storage were observed,and the contents of soluble solid,weight loss,soluble protein,anthocya-nin,total flavone,chlorophyll,malondialdehyde and nitrite were determined.Combined with the experimen-tal phenomena and data,the results showed that salicylic acid and pyrazinamide had certain fresh-keeping effects.The combination of 100 μmol/L pyrazinamide and 50 μmol/L salicylic acid had the best fresh-keep-ing effect on Chinese toon bud,which could maintain better morphological character and effectively inhibit the increase of malondialdehyde and nitrite contents during the storage of postharharvest Chinese toon bud.The study can provide some reference for the preservation of Chinese toon bud sinensis and the devel-opment of its sinensis industry.
