The Cassia angustifolia GaM possesses the potential to become a new source of commercial gum due to its high content in the endosperm (about 50%) and its valuable rheological properties. It was suggested, in a similar way as for other GaMs, for usage as an additive in pharmaceutical formulations [188, 246]. Also the Ipomoea seed gum in its natural form, and after modification by grafting, has the potential to be used as a commercial gum [178]. 

Grafting of polyacrylamide onto guar gum [431] and Ipomoea gum [178] in aqueous medium initiated by the potassium persulphate/ascorbic acid redox system was performed in the presence of atmospheric oxygen and Ag" " ions. After grafting, a tremendous increase of the viscosity of both gum solutions was achieved, and the grafted gums were found to be thermally more stable.

An interesting feature of this list is that some of our most troublesome and difficult to control weeds are not suspected allelopathics. Many weeds, such as morningglory (Ipomoea spp.), cocklebur (Xanthium strumarium L.), and sicklepod (Cassia obtusifolia L.), which make almost all lists of serious weed species, are strong competitors with little or no evidence of allelopathic activity. In fact, cocklebur is probably the epitome of what a competitor can be, being even more devastating than... 

Five-g samples of wheat plant material were soaked in 150 ml of water for 10 hr at room temperature. The mixture was filtered and the filtrate used to germinate pitted morningglory (Ipomoea lacunosa L.) and ragweed (Ambrosia artemisiifolia L.) seed. The effect of the extract on germination was tested in the presence and absence of light.

Ipomoea obscura (L.) Ker-Gawl., or obscure morning glory, is a slender climber common on fences. It is native to tropical East Africa, the Mascarene Islands, tropical Asia, throughout the Malay Archipelago, to northern Australia and Fiji. The leaves are cordate to 5 cm long and the flowers are infundibuliform and creamy white (Fig. 35).
