Abstract

The investigations were carried out in 2001-2003 at the Horticulture Experimental Station, University of Agriculture in Szczecin. The influence of truss cutting and application of Ethrel preparation on the flowering and acceleration of ripening of small-sized tomato fruit was studied. The experiment focused on the following factors: methods of acceleration of tomato fruit ripening (truss cutting, Ethrel preparation, truss cutting + Ethrel preparation) and tomato cultivars ('Cheresita F1', 'Favorita F1'). The applied methods had no influence on the number of flowers and germs of the small-sized tomato. The truss cutting increased the percentage of set fruits compared to the number of flowers. The application of Ethrel preparation along with truss cutting significantly increased the early yield of tomato fruits. The Ethrel and truss cutting accelerated the small-sized tomato harvesting by 12 days. Cv. 'Cheresita F1' produced a larger number of flowers, germs and fruits than 'Favorita F1'.

Summary

Introduction

Wp3yw zabiegów przyspieszaj1cych dojrzewanie owoców na kwitnienie i owocowanie pomidora drobnoowocowego W latach 2001-2003 w Akademii Rolniczej w Szczecinie przeprowadzono doœwiadczenie, w którym badano wp3yw ciêcia gron i stosowania preparatu Ethrel na kwitnienie i przyspieszenie dojrzewania owoców pomidora drobnoowocowego. Roœliny kontrolne odmiany ‘Cheresita F1’ oraz te, na grona których aplikowano Ethrel, tworzy3y najwiêcej zawi1zków, œrednio o 22,7 wiêcej w porównaniu do pozosta3ych zabiegów. Pomidory odmiany ‘Cheresita F1’ zawi1za3y najwiêcej owoców na roœlinie w obiekcie kontrolnym (144,46) oraz w przypadku, gdy stosowano Ethrel (143,25).
