Field Beans

1. Broad bean plants caged with bees produced more seeds per pod, more seeds per plant, heavier seeds and a greater weight of seeds per plant than plants caged without bees. They also had more mature pods at the first harvest but the total number of pods picked was about the same for cages with and without bees. The flowering season of plants caged without bees was extended.2. Field bean plants caged with bees had more seeds per pod and more seeds per plant than plants without bees.3. For both crops, plants in the open had about double the number of pods, beans and weight of beans as plants in cages.

1. The reaction of spring and winter types of field beans and of Windsor broad beans to artificial vernalization treatments and to successional field sowing has been studied.2. The broad bean type came into flower earlier and at a lower node on the stem than any of the field bean types, and this was not affected by either vernalization treatments or successional sowing.3. The field bean types flowered at a low node when sown in winter, but in summer sowings the level of the first flowering node was much higher; the response of the winter types was more extreme than that of the spring types.4. In the summer sowings vernalized plants came into flower earlier and at a lower node than unvernalized, but in the winter sowings both vernalized and unvernalized material flowered at an equally low node.5. A convention for naming the different stems contributing to the yield was evolved, and using this it was shown that the date of sowing affected the stems produced.6. The survival of plants in the field was not found to be affected by vernalization previous to sowing.

SummaryFusarium solani f. sp. fabae Yu & Fang was isolated from root-rotted field bean (Vicia faba)plants at the Research Farm, Hudeiba Agricultural Research Station, Northern Province, Sudan. This is the first record of this fungus on field beans in the Sudan. Cultural and morphological characteristics of the fungus on potato-dextrose agar (PDA) and the symptoms caused are described.

Vicia Faba L

Debray and Maupas (1896) described a disease of broad beans, Vicia Faba L., occurring in and around Algiers, N. Africa, caused by the stem eelworm, Anguillulina dipsaci, the adults of which were considerably larger than from any other host plant attacked by this species; the females being 1·758 mm. to 2·216 mm., and the males 1·716 mm. to 2·016 mm. long. As far as the writer is aware, from the time their paper appeared to the present time no further record of such giant forms of A. dipsaci has been published. During the past few years the writer has encountered similar large forms in diseased broad bean stems, first in material originating in Portugal and on two later occasions in bean plants grown under ordinary field conditions in this country, and it seems desirable to put on record a short account of his observations.

Pollination And Fertilization

SUMMARYIncidences of pollination and fertilization were surveyed in 21 commercial crops of field beans (16 of winter, 5 of spring) in southern Cambridgeshire (England) in 1982 and 1983. During the first part of the flowering season of winter beans, from 30 to 75% of flowers were not pollinated, and thus could not set pods. Where the pollination was largely spontaneous, relatively few pollinated flowers were fertilized and within them, relatively few ovules were fertilized. Later in the season and through most of the spring-bean flowering season, over 90% of flowers were pollinated and over 75% of ovules were fertilized. Incidences of pollination and fertilization varied greatly among the fields, and provision of hives of honeybees in fields of winter beans was associated with an improvement in the incidence of pollination from poor to moderate in 1983 but not in 1982. It is concluded that the incidence of pollination in many fields of winter beans is too low early in the season for an optimum distribution of yield along the stems.

SUMMARYFertilization of four field bean cultivars was examined in irrigated and non-irrigated plots. The overall fertilization of the ovules examined was 33%; in irrigated plots it was 25% and in non-irrigated plots, 41%. Only 48% of fully formed flowers had at least one fertilized ovule. Fertilized ovules occurred most frequently at the first ovule position in the ovary (nearest the stigma), and this frequency declined at successive ovule positions. There was in general a higher fertilization percentage at the upper flowering nodes while fertilization percentage dropped from the first flower position in a raceme to the last. At all the flowering nodes and raceme-flower positions, the cultivars Erfordia and Outlook generally had a higher fertilization frequency than Maris Bead or TI. The significance of these results is discussed.

Broad Beans

Adequate nutrient intake, especially of protein and micronutrients, enhances growth of children and decreases susceptibility to disease. Major contributing factors to malnutrition among infants and children are low purchasing power of the family resulting in poor quality foods. A cross-sectional and laboratory-based study was conducted at Titecha Kebele in Ethiopia to assess the consumption pattern of broad bean. The work also assessed use of broad bean for complementary feeding of young children, following FAO/WHO/UNU’s recommendation of adding up to a maximum of 40% legumes to cereal-based complementary food for young children. Study participants were mother-child pairs (n=169), and children were between 6-35 months of age. Most families were in poverty with stunting, wasting, and underweight present in 22.5, 4.7, and 8.3% of study children, respectively. Questionnaires gathered information on dietary intakes, and focus group discussions were used to obtain indepth information on the mother’s attitude and knowledge of child feeding, as well as overall consumption of broad beans. The mean dietary diversity score of children was approximately two out of a possible eight, and no child had consumed meat, fish, or vitamin A-containing fruits or vegetables the day before the study. Sixty percent of mothers did not provide bean-based food for their children, with the most frequently reported reason being lack of knowledge of its nutrient value for young children. To a typical complementary food of barley-maize porridge, 10, 20 and 30% of cereal was replaced by processed broad beans (Vicia faba), which increased in protein content, with no meaningful change in phytate content. Sensory evaluation showed that participant children and mothers preferred the taste of the 10% broad bean porridge; however, all added broad bean porridges had similar acceptability to the barley-maize control. Thus, inclusion of processed broad bean can effectively be done to improve nutrient content and nutrient availability of traditional cereal-based complementary foods in the Titecha kebele region of Ethiopia.

Floral Nectaries

The floral nectary of Vicia faba L. (faba bean, broad bean, or field bean) consists of a disk which bears a long, basal, tapered projection. Large, open stomata, located at the tip of the projection, probably serve as exits for nectar. Phloem is present in the floral nectary. The extrafloral nectary consists of numerous secretory and nonsecretory trichomes aggregated on the abaxial surface of each stipule. Both xylem and phloem are present in the stipule beneath the extrafloral nectary. In both nectary types, large companion cells accompany the phloem. Epidermal and parenchyma cells of the floral gland, as well as the companion cells, develop wall ingrowths and are therefore transfer cells. Ultrastructural evidence suggests a granulocrine mechanism of nectar secretion in the floral nectary, wherein both apoplastic and symplastic routes for prenectar movement and escape appear feasible. Floral and extrafloral nectar differ in sugar concentration and in the predominance of sucrose, both of which are higher in exudate from floral nectaries.
