Indeterminate tomato hybrid Raisa plants were grown in autumn and spring 1998 in non-heated polyethylene greenhouses to determine the effect of defoliation on dry matter accumulation and distribution to fruits. In autumn, average daily radiation fell below 8.4 MJ m-2 day-1, at about 51 days after planting. In spring, average radiation were still low in the weeks just after planting and reached about 13.3 MJ m-2 day-1 when fruits began to ripen. Treatments consisted of plant bearing one, two, and three (control) leaves per sympod, by pruning leaves below each new truss, just after their appearance. The number of leaves per plant differed by a factor of about 2 and 3, as a consequence of pruning, affecting fruit set, and consequently, the number of fruits per plant. No constant ratio was found between number of leaves and fruits. The total dry matter was higher on plants with 3 leaves per sympod, but fruit dry matter did not differ significantly among the treatments in both seasons.
