Pharbitis

The alkaline hydrolysis of the ether-insoluble resin glycoside fraction from seeds of Ipomoea nil (L.) Roth (syn. Pharbitis nil Choisy) yielded a pentasaccharide of ipurolic acid, which was named pharbitic acid C (tetradecanoic acid, ll-[(0-6-deoxy- S-D-glucopyranosyl-(1 4)-0-6-deoxy-a-L-mannopyranosyl-(l—>6)-0-[6-deoxy-a-L-mannopyranosyl-(l—>2)-0-jS-D-glucopyranosyl-(l—>2)]- S-D-glucopyra-nosyl)oxy]-3-hydroxy). On complete hydrolysis, it produced two o-glucoses, two L-rhamnoses, one o-quinovose, and the aglycone moiety (77).

A combination of the rice lamina inclination assay and GC/MS or GC/SIM analyses have allowed for identification of the brassinosteroids in various plant tissues These include brassinolide, 6-deoxodihydrocastasterone, brassinone from the insect galls of Castanea crenata (18,20) castasterone and 6-deoxodihydrocastasterone from the stems, leaves and flowers of Castanea crenata (20) brassinolide, castasterone, typhasterol (7), and teasterone (8) from leaves of Thea sinensis (21-23) castasterone and brassinone from the fruit of Pharbitis purpurea ( Japanese morning glory ) (24) brassinolide, castasterone and 24-epibrassinolide(29) from immature seed and/or pollen of Vida faba (broad bean ) (25,26) brassinolide and castasterone from the pollen of Alnus glutinosa (European alder) (27).

Another possible reason why GA treatments do not induce flower initiation may be due to improper timing and/or supraoptimal doses. For example, exogenous GAs either promoted or inhibited flower formation (as measured by number of flower buds produced) in plants of the dwarf strain Kidachi of the SDP Pharbitis nil that were marginally induced by 1 inductive long night. Promotion of flowering was observed when the GA treatment occurred 11 to 17 h before the inductive dark period, while GA application immediately after the inductive dark period caused a reduction in the flowering response [9, 18].
