| Abstract:
Strawberries (Fragaria x ananassa Duch.) cv. Pajaro, recently introduced in the South of Chile, present problems of uneven distribution of the red colour during ripening. In the preliminary work here presented chlorophyllous pigments and chlorophyllase activity was analysed in fruit at three different stages of maturity. Chlorophyllase activity in green (polar diameter 1.798 cm, equatorial diameter 1.295 cm, weight 1.687 g), light green (polar diameter 2.360 cm, equatorial diameter 1.93 cm, weight 3.156 g) and ¾ red fruit (polar diameter 3.372 cm, equatorial diameter 2.592 cm, weight 15.659 g) was 8.95 ± 0.70 nmol chlorophyll/h g f.w., 7.57 ± 1.05 nmol chlorophyll /h g f.w. and 3.85 ± 0.18 nmol chlorophyll/h g f.w., respectively. | |
