Abstract: | Results of experiments concerning comparison of tomato fruit properties which were collected from plants obtained in three manners are described. Control plants were received from seeds. Remaining plants were derived in vitro from leaf and shoot fragments on MS medium supplemented with IAA 0.2 mg·l−1 and BA 2 mg·l−1 (Górecka and Krzyżanowska 1991, Górecka et al. 1994) or with Fari’s et al. (1992) method of obtaining plants by decapitation of sterile seedlings and culture on MS medium without hormones. Evaluation of physical and chemical fruit characters was performed. In the spring experiment the biggest diameter (72 mm), weight (154 g) and volumne (151 ml) were characterized to fruits from plants obtained in vitro on MS medium with IAA and BA. Also fruits from plants received by Fari’s methods were significantly superior in these characters over fruits from the control plants. The fruits from the plants obtained in vitro on MS medium with IAA and BA had highest sugar content (2.95 % f.wt.) and fruits from in vitro plants after Fari’s method contained highest vit.C-13.4 mg·100 g−1 f.wt (significant differences in comparison to control fruits). In other characters fruits from in vitro did not differ as compared to control ones. In the autumn experiments significant differences among fruit groups and characters evaluated were not stated. Generally, yield quality was poorer in the all autumn treatments. |
