Atmospheric carbon dioxide (CO2) concentration has increased from 280 ppm (parts per million, mole fraction basis) in preindustrial times to 370 ppm today. As concentrations of CO2 and other greenhouse gases rise, global temperature is anticipated to increase. Elevated CO2 will improve crop yields due to increased photosynthesis. However, at above-optimum temperatures for reproductive growth pr...

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 new growth inhibitor, tentatively named pisumin, which increased under red light and remained at initial level or decreased when dwarf pea (Pisum sativum L. cv Progress No. 9) seedlings were transferred from red light to dark, has been isolated in the form of a colorless powder from light-exposed epicotyls of dwarf peas, and characterized partially as an aliphatic carboxylic acid (molecular w...

 Gregor Mendel. Conducted hybridization experiments on garden peas for seven years (1856 – 1863) and proposed laws of inheritance.  Mendel conducted artificial pollination/cross pollination experiments using several true-breeding pea lines.  A true breeding line is one that, having undergone continuous self-pollination for several generations.  Mendel selected 14 true-breeding peas’ plant v...

The number of psychiatric patients requesting Euthanasia or Assisted Suicide (EAS) continues to increase. aims this systematic review were to: 1) describe the available data related having received EAS (pEAS) for each country in which is allowed; 2) and ethically salient points that arise. PubMed, PsycINFO, Scopus databases searched identify articles published up September 2020. Among retrieved...

Field pea (Pisum sativum L.) and wheat (Triticum sativum L.) were either sole cropped or intercropped in a complete design of five relative proportions and five density levels to determine the effects of interspecific interaction in an intercrop on wheat baking quality. It is shown how pea interspecific competitive ability for factors such as light and water results in an increase in wheat prot...
