Avocado cultivation in the world and Turkey, especially Hass cultivar,
increases rapidly in recent years. The fruit quality of avocado is directly related
to harvest maturity and post-harvest ripening process and the identification of
maturity index has a very large commercial importance. For this purpose; in
the fruit samples of Hass cultivar taken at 15-20 days interval from October to
June, some fruit quality traits (dry matter, flesh firmness, weight loss, taste,
colour of fruit skin and flesh) during the harvest and ripening process and
relationships between of these parameters were analysed. As a result, it was
found that the most reliable maturity index was the dry matter (DM) content
and that there was a direct relationship between its accumulation and the
harvesting time. In cases these index values were insufficient, the other
postharvest analyses (taste, fruit skin colour, fruit hardness and weight loss)
made a contribution to determination of maturity. During the ripening process,
very high levels of a positive correlation between harvest time and dry matter
(r= 0.92 to 0.96) was observed. According to the fruit maturity of the Hass
cultivar, three different harvest periods were defined as early, optimum (most
suitable) and late harvests. It was determined that from early October to late
December as early harvest (23-25% DM), from January to late May as
optimum harvest (26-37% DM), and from beginning to end of June as late
harvest (≥38% DM).
