Abstract

The purpose of this study was to determine the effects of gibberellic acid (GA 3 ) on male and female sterility, seed yield, oil and fatty acid syntheses, growth and development properties in safflower ( Carthamus tinctorius var. Yenice). GA 3 was applied in five different doses at three different stages, and induced male sterility at a rate of up to 93.0%. This finding has important implications for the practical use of GA 3 in hybrid seed production. GA 3 applications significantly decreased the seed yield per plant both in isolation and non-isolation. Although fatty acid syntheses did not change with any application, oil synthesis increased significantly from 33.8% to 38.8% with the application of 300 ppm GA 3 at the budding stage.

Özet

Bu çalışmada, gibberellik asit (GA3) uygulamalarının aspirde ( Carthamus tinctorius L.) erkek ve dişi kısırlığı uyarımı, tohum verimi, yag ve yag asitleri sentezi ile büyüme ve gelişme özellikleri üzerine etkileri araştırılmıştır. Üç farklı dönemde ve beş farklı dozda uygulanan GA3'in, % 93.0 oranlarına varan erkek kısırlığa neden olduğu, böylece hibrid tohum üretiminde GA3'den pratik olarak faydalanılabileceği belirlenmiştir. Hem izolasyonlu hem de izolasyonsuz koşullarda GA3'in tohum verimini önemli miktarlarda düşürdüğü saptanmıştır. GA3 uygulamalarının yağ asitleri sentezi üzerinde önemli bir etkisi olmadığı, tomurcuk döneminde uygulanan 300 ppm GA3'in ise yağ sentezini % 33.8'den % 38.8'e kadar artırdığı tespit edilmiştir.
