Abstract

Inventia se refera la agricultura, in particular la o metoda de selectare a genotipurilor de tomate rezistente la temperaturi inalte. Metoda de selectare a genotipurilor de tomate rezistente la temperaturi inalte include colectarea florilor complet deschise, separarea anterelor si polenului, divizarea polenului in trei parti, amplasarea fiecarei parti in termostate cu trei fonduri de temperatura: 38, 45 si 48°C si tratarea polenului la fiecare temperatura mentionata timp de 3, 4 si 6 ore, semanarea polenului tratat pe mediul nutritiv, care contine, in % mas.: zaharoza 15, acid boric 0,006 si apa distilata restul, si cultivarea lui timp de trei ore la temperatura de 27°C, determinarea viabilitatii polenului dupa raportul dintre numarul de grauncioare de polen germinate si numarul total de grauncioare analizate, exprimate in procente, cu prelucrarea ulterioara a datelor obtinute prin metoda de analiza dispersionala trifactoriala cu determinarea indicilor capacitatii de adaptibilitate integrala dupa valorile medii ale viabilitatii polenului pe toate fondurile de temperatura, capacitatii de adaptibilitate specifica dupa actiunea de lunga durata a temperaturii si capacitatii de adaptibilitate specifica dupa actiunea nivelului inalt al temperaturilor, fiind selectate genotipurile care au indicii determinati mai inalti.The invention relates to agriculture, in particular to a method for selecting genotypes of tomatoes resistant to high temperatures. The method of selecting genotypes of high temperature resistant tomatoes includes collecting fully open flowers, separating anthers and pollen, dividing pollen into three parts, placing each part in thermostats with three temperature backgrounds: 38, 45 and 48 ° C and treating pollen at each mentioned temperature for 3, 4 and 6 hours, sowing the pollen treated on the nutrient medium, which contains, in% mass .: sucrose 15, boric acid 0.006 and the rest distilled water, and its cultivation for three hours at a temperature of 27 ° C, determination of pollen viability according to the ratio between the number of germinated pollen grains and the total number of analyzed grains, expressed as a percentage, with subsequent processing of data obtained by the method of three-factor dispersal analysis on all temperature backgrounds, the specific adaptability capacity du for the long-term action of the temperature and the specific adaptability capacity after the action of the high temperature level, being selected the genotypes that have higher determined indices.
