A new indole-3-acetic acid metabolite was isolated from broad bean (Vicia faba L. cv Chukyo) seedlings. It was a conjugate of dioxindole-3-acetic acid, aspartic acid, and glucose and was identified as 3-(O-beta-glucosyl)-2-indolone-3-acetylaspartic acid (molecular weight 484) from ultraviolet, infrared, nuclear magnetic resonance, and mass spectra. Its natural content in 4-day-old Vicia seedlin...

With isolated epidermal strips of Vicia faba, the intensity of potassium-staining in the guard cells of stomata was calibrated against the uptake of radioactively labeled potassium. By using this calibration, the quantity of potassium that had accumulated in the guard cells, as stomata of leaves of Vicia open in the light, was estimated. Results support the hypothesis that in leaves, as well as...

The article provides an overview of information on the two invasive species of Siberia that are weeds of crops Malva verticillata L. and Vicia hirsuta (L.) S.F. Gray. It provides information on the distribution of species, morphology, biological and ecological characteristics. Active ability of Vicia hirsuta to spread with the seed of oil plants and honey plants was revealed. The possible conse...

Allium cepa, Guard Cell Protoplasts, Malate, Vicia faba Isolated and purified guard cell protoplasts of starch-containing ( Vicia faba) and starch-lacking (Allium cepa) stomata were used to study the metabolism of malate and Clanions as correlated with the K +-induced swelling of protoplasts. The correlation between swelling and malate synthesis in starch-containing and the inhibition of this c...

Broad bean (Vicia faba L.) is an important crop worldwide. An increase in seed yield would increase both the grain reserve and the profit for farmers. Previous studies on increasing broad bean seed yield have focused mainly on increases at the whole population level. Few studies have focused on the differences in plant type within populations. In this study, we classified broad bean plants into...

New discoveries of legumes in the lower Galilee at the prehistoric site of Ahihud in Israel shed light on early farming systems in the southern Levant. Radiocarbon dating of twelve legumes from pits and floors indicate that the farming of legumes was practiced in southern Levant as early as 10.240-10.200 (1σ) ago. The legumes were collected from pits and other domestic contexts dated to the Ear...

The activity of cathepsin D inhibitor is markedly higher in common vetch seed coat than in embryo cotyledons. The occurrence of considerable amounts of the inhibitor in the seed coat of vetch was confirmed by the fluorescent microscopic technique, with the use of fluorescein-marked cathepsin D.

The nitrogen (N) effect of legumes is one of the main reasons for their inclusion in rotation systems and their success in rainfed agriculture of Mediterranean areas. The comparative analysis of this effect in relation to alternative systems or practices is essential for a comprehensive appreciation in their merit. This field experiment was comprised of four three-year rotation cycles. Wheat (T...
