Özet

Kabuǧuyufka is one of the table grape varieties grown in Turkey. However, it shows both flower drop and shatter berry formation (millerandage). In this study, GA3+CCC and CCC were applied for overcoming this problem of this grape variety and ovule development was also investigated. Plant Growth Regulator (PGR) application did not effect the anatomical structure of megasporogenesis and megagametogenesis. The abortion of embryo sac and ovule appeared after full bloom. Zygote degenerated two weeks after full bloom. Most of the control sample sections showed embryo and endosperm degeneration at about three weeks later than full bloom. Application of PGR's increased the number of developing ovule in the berry and slightly decreased the size of ovule in normal sized berries. © Academic Journals Inc.
