Trypsin inhibitor contents of lupin seeds and other grain legumes

Abstract: Analyses for trypsin inhibitor were carried out on a group of legume seed samples previously evaluated nutritionally in rat growth studies. Sweet lupin seeds (Lupinus albus and L. angustifolius) had no detectable amount of inhibitor (less than 0.1 mg/g). Glycine max (soya beans) had 26.2 mg/g. Phaseolus lunatus (lima beans) and three varieties of P. vulgaris had 10–20 mg/g; the variety called “pinto beans” had an inhibitor level within the range 2.0–3.5 mg/g shown by field peas (Pisum sativum) and broad beans (Vicia faba). Wrinkled garden peas (P. sativum) had less than 1 mg/g which was of the same order of magnitude as commercial, imported soya bean meal and other heat processed soya bean. Common beans and peas had no detectable trypsin inhibitor after boiling in water for 1 h and freeze-drying.

Notizen: Phytoalexin Production by Flowers of Garden Pea (Pisum sativum )

Abstract: Abstract The isoflavonoid phytoalexin pisatin has been isolated from fungus-inoculated petals of 16 Pisum sativum cultivars. Pisatin was usually accompanied by trace quantities of maackiain. No other fungitoxic compounds were detected.

Variability in number of pods and yield in commercial crops of vining peas ( Pisum sativum L.)

Abstract: Data were collected from 218 commercial crops of vining peas ( Pisum sativum cv. Dark Skinned Perfection) to test the hypothesis that variability between commercial crops in the yield of vining peas is associated with variation in the number of pods per plant. Yield varied widely between crops; the coefficient of variation of crop yield adjusted to tenderometer reading 105 was 25%. Only a small part of this variation could be accounted for by the correlation between yield and the estimated number of pods per plant ( r = 0·067, 216 D.F.), and significance levels were not substantially improved by allowing for the effects of sowing date and plant density, or by using data on number of pods at each separate node in place of the overall totals per plant. Consequently the hypothesis stated above is not supported and it is suggested that variation in the weight of peas per pod was the main cause of variation in yield between crops. A number of significant relationships were noted in the correlation analyses; (1) the mean number of pods per node at adjacent nodes tended to be positively correlated; (2) the number of pods per node at the first podding node tended to be positively correlated with plant density; (3) the numbers at the upper nodes tended to be negatively correlated with sowing date and with harvest date.

Associative effect of inoculation of different strains of Azotobacter and homologous rhizobium on the yield of moong (Vigna radiata), soybean (Glycine max) and pea (Pisum sativum)

Abstract: It has been observed that in the case ofVigna radiata andGlycine max incorporation of suitable strain of Azotobacter gave higher yield than obtained by the use of Rhizobium as inoculant. In the case ofVigna radiata even a strain of Azotobacter isolated from the rhizosphere of berseem gave similar yields as Rhizobium. In the case ofPisum sativum association of Rhizobium with a strain ofAzotobacter chroococcum isolated from the rhizosphere of pea gave numerically higher yield than Rhizobium alone. It may be possible that statistically higher yield may be obtained when a suitable strain of Azotobacter is used after screening a large number of strains of Azotobacter from the rhizosphere of pea.

A comparison of several grain legumes at two sowing times: I. Seed yield and components

Abstract: Cultivars of Lupinus angustifolius, L. albus, L. luteus, Vicia faba, and Pisum sativum were sown on 13 August and 25 October 1974. Some of the later sown plots were irrigated to determine if adequate soil moisture levels could compensate for the late sowings. Early sowings of L. albus cvs. Ultra and Neuland and P. sativum cv. Pamaro gave best seed yields (462,369, and 423 g/m2 respectively) but the L. albus cultivars had greater protein yield than P. sativum (169,139, and 107 g/m2). Late-sown L. albus had significantly higher seed and protein yield than P. sativum. Due to disease and lodging in the irrigated plots, L. albus was the only species to respond to irrigation and yields of seed and protein were similar from early-sown (462 and 444 g/m2 respectively) and irrigated late-sown (169 and 162 g/m2 respectively) treatments. This indicates that moisture availability during the summer influences seed yield from late sowings and that temperature may not be so important. Pod number was the main com...

Chromosome Analysis in Suspension Culture of Vigna Sinensis Var. Black and Pisum Sativum L.

Abstract: SUMMARYThe study on the extent of chromosomal variations in suspension cultures initiated from hypocotyl segments of Pisum sativum var. Arkel and Vigna sinensis var. black reveals aberrations like inhibition of cell plate formation, spindle abnormalities, chromosomal breakage, polyploidy and aneuploidy. Such aberrations are frequently observed mostly in aneuploid cells and their frequencies increase with the number of passages. Asynchronous behaviour of daughter nuclei resulting in multinucleate cells is observed more frequently in cultured tissues of P. sativum L. than in Vigna sinensis var. black. In progressively older passages of Vigna sinensis var. black diploid cell populations gradually increase more rapidly than the tetraploid and aneuploid cells, indicating the selective advantage of diploid cells over others. By contrast in progressively old passages of Pisum sativum L. the frequencies of cells with 11 and 12 chromosomes are high. In the resulting cell population a range from 7 to 14 chromosomes...

Influence of light, phytohormones & acetylcholine on the de novo synthesis of acetylcholinesterase in roots of Pisum sativum

Abstract: Pisum sativum seeds contain a conserved acetylcholinesterase (AChE) which is active during the early stages of germination. The enzyme activity soon disappears and reappears after 72 hr of germination. A protein devoid of catalytic ability, but exhibiting similar chromatographic and electrophoretic properties as the active AChE, could be detected after 24 hr of germination. The pattern of incorporation of labelled amino acids into AChE and the influence of cycloheximide revealed that the AChE found in the roots from 72 hr onwards was entirely new. During this period of growth, the AChE protein accounts for 4–10% of the total proteins in the root tissue.

The vitamin A and C content of Coriandrum sativum and the variations in the loss of the latter with various methods of food preparation and preservation

Abstract: The leaves ofCoriandrum sativum contain 51.4µg of betacarotene (85.6 IU) per gram and 361mg L-ascorbic acid per 100g on a dry weight basis. The vitamin C in the plant did not change significantly for three days when the cut stems were placed in water and maintained at a temperature of 17 °C. Cooking for 5 minutes lowered the vitamin C content in 4 and 10 volumes of water by 41 to 49% and 61 to 67%, respectively. Cooking for 10 minutes in the same amount of water increased the loss by a few percentage points.

The effect of cultivation temperature on nitrate reductase, glutamine synthetase and glutamate dehydrogenase levels in isolatedPisum sativum roots

Abstract: Nitrate reductase (NR), glutamine synthetase (GS), and glutamate dehydrogenase (GDH) levels are differently influenced by cultivation temperature, NR level being influenced most and GDH level least. The differences caused by cultivation temperature are more pronounced in roots cultivated without sucrose in which a slower decrease in NR and GS levels and a lower increase in GDH level occur at 14 and 18 °C than at 24 °C in comparison to roots cultivated with sucrose. Sugar consumption also tends to be slower at 14 °C than at 24 °C in roots cultivated without sucrose.
