Not AvailableConcentration of endogenous gibberellic acid (GA3), abscisic acid (ABA) and indole-3 acetic acid (IAA)
in achenes and pericarp of two varieties viz., ‘Crifty Duty’ and ‘Five Star’, were determined at weekly
interval starting from 14th till 63rd days after pollination (DAP). GA3 content in achenes initially
increased till 35-42 DAP, while ABA was low during the period. In pericarp of both the varieties, ABA
content was more than GA3 while in achenes, ABA content was lower than that of GA3. Proportion of
GA3 to ABA was found to be higher in achenes of 'Five Star' compared to that of 'Crifty Duty' except at
35 DAP, where in the proportion of GA3 over ABA was more in 'Crifty Duty' compared to 'Five Star'.
Maximum IAA content was recorded at 42 DAP and 35 DAP respectively in achenes of ‘Crifty Duty’
and ‘Five Star’ suggesting its role in embryo development.Not Availabl
