This invention relates to (22R,23R,24S)-22,23-epoxy2.alpha.3.alpha.-isopropylidenedioxy-B-homo-7-oxa-5.alpha.-stigmastan-6-one which is of value as a plant growth regulator, a process for preparation thereof and a plant growth regulating composition containing the same.
摘要:
A plant growth promoter comprising as the active ingredients (i) a jasmonic acid or jasmonate of the formula (1): ##STR1## wherein R.sup.1 is pentyl or pentenyl and R.sup.2 is hydrogen or alkyl, and (ii) a brassinosteroid of the formula (2): ##STR2##
摘要:
A composition for inhibiting flowering of plants and a composition for prolonging the duration of flowering are disclosed. The compositions of the present invention comprise S-(+)-abscisic acid as an effective ingredient.
摘要:
The present invention provides plant growth promoters each comprising, as an active ingredient, a jasmonic acid derivative represented by the following formula: ##STR1## wherein R.sup.1 represents a pentyl group or a pentenyl group and R.sup.2 represents a hydrogen atom or an alkyl group. These promoters exhibit excellent growth promotion effects particularly on root vegetables, potatoes (tuber crops), cereals, fruit vegetables, fruit trees, flowers and ornamental plants and industrial crops.
摘要:
The present invention relates to a plant growth regulator comprising as an active ingredient an epoxycyclohexane derivative represented by general formula (1): ##STR1## wherein R.sup.1 is a hydrogen atom, a C.sub.1 -C.sub.6, alkyl group or C.sub.3 -C.sub.6 cycloalkyl group, and R.sup.2 and R.sup.3 are independently C.sub.1 -C.sub.6 alkyl groups or are combined to form a C.sub.2 -C.sub.3 polymethylene group which may be substituted with a C.sub.1 -C.sub.6, alkyl group, as well as to a plant growth regulator comprising the epoxycyclohexane derivative and a brassinosteroid as active ingredients. The epoxycyclohexane derivatives exhibit a potent plant growth regulating action which is equivalent to or higher than that of abscisic acid, and are useful as plant growth regulators such as a plant growth accelerator, a germination growth accelerator, a transpiration and wilting inhibitor, a cold resistance enhancer, an accelerator for growing, thickening or maturing fruits, roots, stems or bulbs, etc.. A synergistic effect is achieved by combination of the epoxycyclohexane derivative with a brassinosteroid.
摘要:
A plant growth regulator comprising as the active ingredients gibberellin and a jasmonic acid ester represented by the following formula (1): ##STR1## wherein R.sup.1 and R.sup.2 represent hydrocarbon groups. Gibberellin and the jasmonic acid ester are applied as a mixture, or as single agents each containing one of the two compounds, which are applied concurrently, or separately by a procedure wherein, while the earlier applied one is still in force, the other is applied.
摘要:
Brassinosteroid derivatives expressed in formula (I) and formula (II) ##STR1## and a plant growth regulator containing one type or two types of these brassinosteroid derivatives as active ingredient. The invention thereby presents novel brassinosteroid analogous compounds expressed in formula (I) and formula (II) and a plant growth regulator containing these compounds showing a persisting plant growth regulating action.
