TAILIEUCHUNG - Correlations between changes in the amount of endogenous phytohormones and flowering in the safflower (Carthamus tinctorius L.)

Changes in the amounts of endogenous gibberellic acid (GA3), indole-3-acedic acid (IAA) and abscisic acid (ABA) during different growth periods of the safflower were studied by high-performance liquid chromatography (HPLC). | Tr.

A correlation was confirmed between low levels of GA , as well as high levels of ABA, and the initia3 tion of flowering. IAA reached its maximum level during bud formation, indicating that IAA might play an active role in the differentiation of bud formation. Changes in the amount of endogenous phytohormones in flower buds located in different parts of the plant indicate that ABA in particular plays an important role in the formation of flowering order in safflower. Key Words: Carthamus tinctorius L., flowering buds, phytohormones, HPLC Aspir Bitkisinde (Carthamus tinctorius L.) İçsel Hormon Düzeyindeki Değişimler ile Çiçeklenme Arasındaki İlişkiler Özet: Aspir bitkisinin farklı büyüme dönemlerinde içsel gibberellik asit (GA3), indol-3-asetik asit (IAA) ve absisik asit (ABA) değişimleri yüksek basınçlı sıvı kromatografisi (HPLC) ile incelenmiştir. GA ’in düşük ve ABA’in yüksek düzeyleri ile çiçeklenmenin uyarılması arasında yakın bir ilişkisinin varlığı 3 saptanmıştır. En yüksek IAA düzeylerine tomurcuklanma döneminde ulaşılmıştır. Bu sonuç, aspir bitkisinin çiçek tomurcuğu farklılaşmasında, IAA’in etkin bir rol oynadığını göstermiştir. Aspir bitkisinin konumları farklı çiçek tomurcuklarındaki içsel hormon değişimleri, çiçeklenme düzenin oluşumunda özellikle ABA’in etkin rol oynadığını ortaya koymuştur.
