Several photosystems control leaf expansion in Alaska peas (Pisum sativum). Phytochrome is known to control expansion in dark-grown peas. But plants exposed briefly to red light are insensitive to phytochrome, an insensitivity that is itself phytochrome-produced. Leaf expansion in these plants is promoted by 440 or 630 nm of light (probably mediated by protochlorophyll). Plants grown in white f...

A total of 122 accessions of different wild and cultivated Pisum sp. were analysed using retrotransposon-based insertion polymorphisms (RBIP) markers. The Pisum materials included wild and cultivated (landraces and cultivars) materials from the World core collection of the John Innes Centre (JI) representing all generally recognized Pisum taxa, landraces materials from the Spanish core collecti...

Activity of endogenous auxins and growth inhibitors, gibberellins and cytokinins was observed in the extracts of seedlings of Pisum sativum under NaCl stress. After 6 days of germination, when Pisum sativum seedlings were subjected to low concentration of NaCl (50 mM) or boron (10 ppm) increased the endogenous growth regulating substances. Higher concentration of NaCl (150 mM) decreased endogen...

The effects of soil inoculation with phosphoriencontaining phosphate-dissolving bacteria (PDB) and/or magnesium (Mg) foliar application at the rates of 0, 0.5 and 1mM on growth, green pod and seed yields, and chemical constituents of Pisum sativum L. grown on a sandy calcareous soil were investigated. Results indicated that PDB and/or Mg significantly increased shoot length, number of branches ...

Studies with stem segments of peas (Pisum sativum L. var. Alaska) suggest that the pH of the medium bathing elongating tissue does not always reflect intramural (cell wall) conditions or that pH is not a controlling factor in elongation. Peeled, green segments, and peeled or nonpeeled etiolated segments appear to regulate the pH of their bathing medium causing it to become acidified with or wit...

Rhizobium leguminosarum bv. viciae GB30 is an aerobic, motile, Gram-negative, non-spore-forming rod that can exist as a soil saprophyte or as a legume microsymbiont of Pisum sativum. GB30 was isolated in Poland from a nodule recovered from the roots of Pisum sativum growing at Janow. GB30 is also an effective microsymbiont of the annual forage legumes vetch and pea. Here we describe the feature...

Lectins are present in microorganisms, plants and animals and have attracted great interest due to their varied physiological roles in cell agglutination, anti-tumour, immunomodulatory, antifungal and antiviral effects. Legume lectins are important to the pharmaceuticals but they are produced in low amounts in the plant seeds. Moreover, the genes controlling these proteins are conditionally act...

In a study of the effect of soil bacteria upon the etching power of the roots of Canada field peas upon polished marble, it has been shown that the presence of the bacteria increases the etching power of the roots.

A study was conducted to check the effect of different sowing dates and row spacing on the growth, seed yield and quality of offseason pea (Pisum sativum L. cv. Climax). Significant differences were recorded among sowing dates for days to germination while nonsignificant results were found for row spacing and interaction (A × B). Maximum days to germination were recorded in D1 (20 th April) and...
