Maturity Degree

The chemical composition of strawberry fruit depends mainly on cultivar, fruit maturity degree and climatic conditions in the growing period. Fruit quality is also determined by a cultivation technology. The influence of two biostimulants (Atonik SL and Betokson Super 050 SL), which were used separately, in combination with each other or with the liquid fertilizer InsolCa, on yielding and fruit quality of two strawberry cultivars: ‘Senga Sengana’ and ‘Kent’, was tested. Betokson Super 050 SL + InsolCa tended to improve the yield of both cultivars. Significant differences compared to the control were evident especially in 2001. Fruits of ‘Senga Sengana’ started ripening later and had more ascorbic acid, anthocyanins and acidity than ‘Kent’. The use of Betokson Super 050 SL + InsolCa improved the content of ascorbic acid, anthocyanins and sugar as well as acidity in strawberries of both cultivars. The use of Betokson Super 050 SL + Atonik SL significantly increased the content of ascorbic acid and sugar in fruits of both cultivars. ‘Kent’ strawberries also responded to the treatment with an increase in anthocyanin content and acidity.

The quality of pineapple guava fruits during post-harvest storage depends directly on their quality at harvest and is influenced by climatic conditions during growth. The aim of this study was to determine the influence of climatic conditions on certain parameters of fruit quality during post-harvest storage. Twenty trees were tagged in two locations within the department of Cundinamarca (Colombia), recording the climatic conditions during fruit growth until harvest. The fruits were differentiated by place of origin and stored at 18 ± 1ºC (76 ± 5% relative humidity, RH) for 11 d or 5 ± 1ºC (87 ± 5% RH) for 31 d, evaluating several quality attributes every two d. The places of origin were San Francisco de Sales (1,800 m a.s.l., 20.6oC, 63-97% RH, with an average annual precipitation of 1,493 mm) and Tenjo (2,580 m a.s.l., 12.5oC, 74-86% RH, with an average annual precipitation of 765 mm). The results indicated that the fruits stored at the highest temperature were sweeter and had reduced weight and firmness, lower acidity, and faster postharvest senescence (lower post-harvest durability). The postharvestN fruit characteristics were determined by considering the fruit quality during growth and the influence of climatic conditions during cultivation in each location. At the higher altitudes, the total soluble solid content in the fruits was higher and firmness decreased, and the total titratable acidity and weight loss were lower. For fruit color, significant differences were not observed that would demonstrate the effect of climatic conditions during the post-harvest period.
