Evaluation of some varieties and breeding lines of tomatoes Lycopersicon esculentum, Mill.) in regard to leaf area and leaf efficiency and relation of partial defoliation to early and total yields, fruit size, soluble solids, leaf rolling, and blossom-end rot



Evaluation of some varieties and breeding lines of tomatoes Lycopersicon esculentum, Mill.) in regard to leaf area and leaf efficiency and relation of partial defoliation to early and total yields, fruit size, soluble solids, leaf rolling, and blossom-end rot



Diss. Abstr 22: 4146-7



Early yields of partially defoliated plants were greater than those of control plants in tests with 7 varieties, both early and late. Total yields of all varieties were highest on the control plants, except for San Marzano which yielded as well with 40 leaves or with two-thirds of its foliage as with all its foliage. Fruit size decreased as the number of leaves was reduced, except for Geneva 11 which produced larger fruits on plants grown with 40 leaves than on the controls.
