Abstract:
Taking ‘Whangkeumbae’ as materials,by using the microscopic section dyeing technology,the contents of pectin，cellulose，callose and starch in the flesh tissue of ‘Whangkeumbae’ pear fruit with or without ‘hardend disorder’ were observated.The results showed that disease fruit had a high stone cell density，big volume and high cellulose content comparison with normal fruit.The content of callose had no obvious difference between diseased fruit and normal fruit.In addition，the contents of starch grains and pectin in diseased fruit were increased，and near the skin forming block mass compared to normal fruit.These results indicated that ‘hardend disorder’ of ‘Whangkeumbae’ was related to cell size，pectin and cellulose contents of flesh tissue.The cellulose and pectin increase of flesh tissue may be one of the causes of pulp hardening.
