Hyacinth Bean

 

(Dolichos lablab), an herbacious, generally twining plant of the family Leguminosae. The leaves are trifolio-late. The large, fragrant flowers are white, reddish, or purple; they are in axillary racemes. The fruit is a pod, with three or four globose, ovate, or flattened seeds. The hyacinth bean has been cultivated since ancient times for food and forage; it does not grow wild. It is cultivated primarily in the tropical and subtropical regions of Asia and Africa. The unripe pods and the ripe seeds are used as food. Many cultural forms are known. The hyacinth bean is grown in Western Europe and the Caucasus as an ornamental.

The results of this study demonstrated that addition of NaCl at a concentration of 0.4 to 0.6 M significantly improved the protein solubility, foaming stability and emulsifying activity of pigeon pea, cowpea, white bean and hyacinth bean flours.
The first involved grafts between soybean and mung bean, and the second involved grafts between soybean and hyacinth bean. Seeds were surface sterilized by immersing in 950 mL [L.sup.-1] ethanol for 10 s, followed by 4 min treatment with 10 g [kg.sup.-1] sodium hypochlorite, and then rinsed four times with sterilized, purified (reverse osmosis) water.
Reciprocal grafts involving mung bean shoots and soybean roots, and hyacinth bean shoots and soybean roots, were also made but not used in the current experiment.
Given that the seedling size of hyacinth bean was approximately twice that of mung bean at the time of grafting (reflecting larger seed size of hyacinth bean), the similar shoot mass of self-grafted hyacinth bean and mung bean plants at harvest (Table 1) indicates that mung bean self grafts were more compatible.
For hyacinth bean grafted combinations, similar nodule numbers occurred for self-grafted hyacinth bean and for Williams 82 soybean shoots grafted to hyacinth bean roots.
With the hyacinth bean graft combinations, the USDA 4787 strain tended to induce greater nodule mass, but was significantly greater in only the hyacinth bean self graft.
