Role of the Cotyledons in the Phototropic Response of Lavatera cretica Seedlings.
Young seedlings of Lavatera cretica L. exhibit positive phototropism. The hypocotyl perceives unilateral illumination with blue light and curves towards the light source by unequal growth. In addition, the cotyledonary laminas perceive the vectorial component of unilateral illumination with blue light and reorient normal to the beam by creating a turgor differential in their pulvini. Excision o...
متن کاملEffects of breathing carbon dioxide upon the pulmonary circulation.
IN THE 2 companion papers, we have considered some effects of acute hypoxia on the pulmonary circulation. The present study, concerned with the effects of acute hypercapnia on the pulmonary eirculation, was prompted by 2 prospects: (1) that an acute increase in alveolar and arterial P 0, brought about by the inhalation of air enriched with carbon dioxide, might simulate the effects on the pulmo...

متن کاملInfluence of Light and Darkness upon Carbon Dioxide Fixation.
For plants sensitive to photoperiodism light is generally essential for flowering, and the requirement for CO2 with the light indicates a photosynthetic function for the light period (21, 10). There appears to be an additional role of light in which it apparently alters a photoreceptor pigment controlling floral initiation (22). Evidence has been advanced recently that CO2 is also essential dur...
