Abstract
There are unexpected cases in apple or pear storage practice, i.e. external effects such as high or low temperatures, CO 2 stress and intensive oxygen pull down may disturb normal ripening of fruits. Physiological consequences of these disturbances are expressed in certain cases only in incomplete ripening, while in irrevocable cases they are manifested as serious tissue damages such as non-parasitic storage disorders known as core flush, soft scald, and internal or external CO 2 injuries. It has been widely demonstrated in pome fruits that in a transient phase of maturity, during the pre-climacteric, ripening of pome fruits is preceded by changes in gene expression, detachment of new mRNA-s and the synthesis of compounds that are certainly essential for ripening processes. It is likely that this transient phase is closely related to changes on molecular level, and therefore, it may be considered as critical when external effects influence fruit life. __
