This study was carried out to evaluate the effects of Gibberellic acid and Paclobutrazol respectively on promote flowering and vegetative growth reduction in strawberry in order to enhance production. Gibberellic acid and paclobutrazol are plant growth regulators. Gibberellic acid can act as a promoter while, paclobutrazol act as an inhibitor. Gibberellic acid at 100 mg/l, 30 and 90 days and pa...
It was observed that acetoacetic acid when coupled with 4-nitrobenzenediazonium salt in a buffered carbonate solution yielded a strong green color upon further alkalization. This reaction was given by relatively few of the biochemical compounds that have been tested, and the procedure has been developed so that, as applied to blood filtrates, it is believed t,o afford a. satisfactory measure of...
