Ripening of climacteric fruits does require ethylene while ripening of non-climacteric fruits does not. Naturally climacteric fruits can produce a threshold value of ethylene to ripening processes but requires many days to do so, which in turn results in a delay in ripening. Stimulation of fruit ripening is to apply externally ethylene or can be done by other means and individual methods have advantages and disadvantages. In addition to shortening of ripening time, stimulation of fruit ripening also results in uniformity of fruit ripening, good colour development, less shriveling and decay. Stimulation of fruit ripening involves many factors and each factor affects quality of ripened fruits. Key words : calcium carbide, climacteric, ethylene, fruit, joss stick, leaf, quality, ripening ∫√√≥“πÿ °√¡ “¬™≈ ‡°µÿ …“. ÚıÚ˘. °“√ ÿ °¢Õߺ≈‰¡â . ¢à “« “√‡°…µ√»“ µ√å ÛÒ(ˆ) : Ò-¯ _______.
