Abstract:
For exploring the causes of the hard-end disorder of ‘Whangkeumbae’ fruits,the fruits with hard-end disease were selected as test materials in the experiment,via the determination of fruit weight,fruit shape index,the color difference,the content of stone cell,pectinesterase (PME),phenylalanine ammonia-lyases (PLA) of disease fruit and normal fruit,to discuss the reason causing to the hard-end disorder of ‘Whangkeumbae’.The results showed that stone cell content in diseased fruit was significantly higher than normal fruit,the PLA activity in diseased fruit was significantly higher than normal fruit,but there was no difference on the PME activity between diseased fruit and normal fruit.The above results pointed out that PLA was closed to the hard-end disorder of Whangkeumbae.However,PME activity had no obvious effect on the pulp hardening.
