Abstract
The invention comprises the compound of the formula below, named gibberellin A7, and its salts and esters:- <FORM:0914893/IV (b)/1> Gibberellin A7 is prepared by cultivating an active strain of Gibberella fujikuroi in an aqueous nutrient medium, and after the active growth of fungus has ceased, adjusting the pH of the medium to, and maintaining it at, a value of 5-9; or by cultivating said active strain in an aqueous nutrient medium in which the initial concentration of the carbon source is 20-45% w/v glucose monohydrate or its equivalent carbon content. The methyl ester of gibberellin A7 is prepared by esterifying the acid with diazomethane; the O-acetyl derivative is prepared using acetic anhydride; the ammonium and sodium salts are prepared from the corresponding hydroxides, and the calcium salt from calcium carbonate. Specification 783,611 is referred to.ALSO:The invention comprises plant growth promoting compositions containing the compound of formula <FORM:0914893/I/1> named gibberellin A7, or a salt or ester thereof (see Group IV(b)), and a carrier or diluent therefor. The compositions may be liquid, such as aqueous or non-aqueous solutions or suspensions which may contain surface-active agents; or solid, such as tablets, powders or granules, which may also contain fertilisers, pesticides and/or antifungal agents. Specification 783,611 is referred to.
