PENGARUH GA3 DAN BEBERAPA JENIS LARUTAN KIMIA TERHADAP BUNGA DAN KARAKTER MORFOLOGIS TETUA PADI HIBRIDA
ABSTRACT: The aim of the
present study is to optimize the dose of GA3 and substitution chemicals that
affect on floral and morphological traits of parental lines for hybrid rice
seed production. The experiment was conducted at glass house on field station
Sukamandi, Indonesian Center for Rice Research, during April-August 2010. The
experimental material comprising both the parental lines of hybrid Hipa 7 i.e.
IR58025A and IR40750 were treated with 10 treatments of different kind of GA3,
chemicals, and one untreated check was grown in randomized block design with
three replications. The results indicated that a liquid GA3 60 ppm, urea 2%,
phosphate 1%, and glycine 40 ppm could influence some of the characters
favoring outcrossing i.e stigma exertion, panicle exertion, anther and filament
length. These chemical (urea 2%, phosphate 1%, and glycine 40 ppm) showed the
possibility of the economizing cost of seed production and substitute of GA3
