| Abstract:
Fruit-stem stiffness is one of many maturity indices used by durian growers. A tool was developed to assess objectively the maturity of durians according to this index. It was made with a "Effegi" firmness tester attached with a multiple plunger head, consisting of six cylinders of 1 mm diameter each. ‘Monthong’ durians were harvested at 104, 111, 118, and 125 days after anthesis for fruit-stem stiffness and maturity evaluation. The stiffness measurement was made by plunging the bark of the lower fruit stem with this tool. The reading was found related to days after anthesis, firmness and soluble solids content of the pulp, and number of phloem fiber in the bark. The possibility of using this tool to determine durian maturity is discussed. | |
