  Phytochrome and Seed Germination VI. Phytochrome and Temperature Interaction in the Control of Cucumber Seed Germination
  Frone A. Eisenstadt 2 and Alberto L. Mancinelli a Department of Biological Sciences, Columbia University, New York, New York 10027 Abstract Phytochrome control of cucumber seed germination is temperature-dependent. A prolonged exposure to radiation from broad spectrum far red sources (Pfr/P =...

  Differential rates of water loss were achieved in picked avocado ( Persea americana Mill.) fruits, either by controlling the evaporation rate or by supplying water through the fruit stalk. A negative linear correlation was found between the daily rate of water loss from fruits and their ripening,...

  Alkaloid Changes in Tobacco Seeds during Germination
  Nicotine, nornicotine, anabasine, and anatabine, normally found in growing and mature tobacco ( Nicotiana tabacum L.) plants, were extracted and quantified from mature tobacco seeds and young tobacco seedlings. The rate of net alkaloid disappearance and accumulation in tobacco seedlings was...

  Greater Length of Ribonucleic Acid Synthesized by Chromatin-bound Polymerase from Auxin-treated Soybean Hypocotyls
  An investigation has been made of the RNA synthesized by chromatin-bound RNA polymerase from soybean hypocotyls ( Glycine max var. Wayne). Polymerase activity is 4- to 5-fold higher with chromatin from tissue treated with 2,4-dichlorophenoxyacetic acid, a synthetic auxin, compared to untreated...

  Rapid Phytochrome-mediated Changes in Adenosine 5′-Triphosphate Content of Etiolated Bean Buds
  This study was designed to determine the effects of red and far red irradiation on ATP metabolism in etiolated bean buds ( Phaseolus vulgaris L. var. Red Kidney). Compared to dark controls, red irradiated buds show an initial decline in ATP content at 15 seconds following a 5-minute irradiation....

  Differential centrifugation of several plant extracts indicates that the majority of the hydroperoxide isomerase activity is present in the cytoplasm of the cell. However, lesser amounts of isomerase activity were found in the mitochondrial and microsomal fractions of sunflower seedlings. Sucrose...

  A Water Potential Threshold for the Increase of Abscisic Acid in Leaves
  A relationship between abscisic acid concentration and leaf water status is reported. Water potentials were measured in leaves of Ambrosia artemisiifolia L. and Ambrosia trifida L. throughout a period of dehydration of intact plants. Tissues from the same leaves were analyzed for abscisic acid....

  A nitrogen-fixing association can be readily established in vitro between Rhizobium and cultured soybean root cells. Plant cells are grown as a thin callus on the surface of solid defined medium containing low levels of inorganic nitrogen and inoculated with bacteria during the active phase of...

  The photosynthetic assimilates in leaves of Perilla crispa attached to the plant were labeled by treating the leaves with 14 CO 2 . When subsequently detached, these leaves exuded a negligible amount of radioactivity from the cut petiole into water. Ethylenediaminetetraacetate (EDTA), citric...

  A Digital Diffusion Porometer Circuit
  An automatic digital diffusion porometer circuit is described. The circuit is highly stable with respect to temperature and supply voltage. The device is capable of high timing accuracy over very short measurement intervals, so that measurements may be made rapidly without the danger of stomatal...
