Abstract
This investigation as ‘conducted in the laboratory of icultu’e Departaent at the Faculty of Agriculture, Assiut
iversity, during two successive years in 1981 and 1982 asons to study the effect of some growth regulators and heat artificial ripening of mature Solo Papaya fruits. Some sical and chemical characteristics of Papaya fruits were
udied during ripening such as; weight and volume of fruits, ;entages of total soluble solids, reducizg sugars and total ‘s as well as starch, total ad di ty ezpressed as grams of .c acid per 100 grams of pulp and vitamin “C” content ressed as MG of ascorbic acid per 100 grams of pulp.
4 Papaya fruits were harvested on first week of both April and 27o ve Z,er 1982 at wifo,iyi’ stage of 1,28 turi v rihe 2 B. 5
‘ded 4 and total acidity as citric acid reached a level 0.08%’. This experiment was planned as factorial in
dcoc1iplete blocks design with three replications.
Representative samples were taken randonily at four days ai until fruits deteriorated after sixteen days. Five ent ripening treatments were used as follows:
Control (at room temperature).
2,4-D at 200 p.p.ni. (ciippin five minutes).
;hrel at 2000 p.p.rn. (dipping five minutes).
