The influence of micephyt preparation on seed productivity ana on qualtity of hybrid seeds of Cucurbita pepo var. Giramontia Duch

Relevance. Biologically active compounds are widely used at the modern vegetable production, and especially at the seed production. Influence of Micephyt preparation in the mixed with Etrel is evaluated at the first time. The goal of the study is evaluation the effect of Micephyt in the mixed of Etrel on the obtaining of hybrid seeds of the squash (Cucurbita pepo var. giramontia Duch.). Materials and methods. Studies were carried out at the experimental plot Transnistrian State University named T.G. Shevchenko (Tiraspol) during 2010-2012. The object of studies was maternal line F1 (166/5x98/5) of squash (analog of commercial hybrid F1 Lenutsa). Materials of study were preparations: Etrel (c= 0 and 300 ppm) and Micephyt in the mixed with Etrel (c= 10 and 100 ppm). There were 2 treatments of squash plants with these preparations: at the stage 2-3 leaves, and at the stage of 6-7 leaves. Results. Treatments maternal line of squash F1 with mixed preparation “Etrel-300 ppm + Micephyt-10 ppm” show the positive effect on the seed productivity of plants...
