Abstract
Earlier studies concerning self-, free- and cross- fertilization of apricot varieties grown in Hungary, proved the existence of self-sterile as well as self-fertile varieties within the recommended assortment.
The self-sterile and partially self-fertile varieties should be planted in association with pollinizer varieties, only.
The present paper reports about the yields of trees of the widely grown, self-sterile local variety, Ceglédi óriás, depending on the distance of adequate pollinizer trees.
In the univarietal, 27 row-wide block of the relevant variety, an efficient pollinizer, Magyar kajszi was planted to the 10th and 19th row.
In the close vicinity, another block of pollinizer Rózsakajszi C. 320 was located.
The number of fruits set per tree has been counted or estimated in two consecutive years.
In both seasons, the yield of the Ceglédi óriás trees diminished with the growing distance from the nearest pollinizers trees.
Those trees in the center of the block, between the two (10th and 19th) rows of Magyar kajszi bore acceptable yield (40 kg/tree in 1987), however, considerable reduction of the number of the fruits set was already stated in the 4–5th row away from the pollinizer.
Similar gradient of fruit set was apparent in relation to the neighbouring block of Rózsakajszi C 320. The beneficial effect of the vicinity of pollinizer varieties was obvious as far as the distance of the 10th row.
Taking into consideration the self-sterility, the early blooming time and the poor fertilization of the variety Ceglédi óriás, a planting design of associating it with at least two pollinizer varieties (e.g. Gönczi magyar kajszi and Ceglédi bíborkajszi) is highly recommended.
On the basis also of earlier results, a proposal has been developed for the association of apricot varieties as recommendations for optimized yields.
Blooming time, fertilizing potential, schedule of the picking season and market possibilities have to be considered simultaneously.
