Temperature optimum of Mycobacterium leprae in mice.
Shepard, Charles C. (Communicable Disease Center, Atlanta, Ga.). Temperature optimum of Mycobacterium leprae in mice. J. Bacteriol. 90:1271-1275. 1965.-Mycobacterium leprae multiplied most rapidly in foot pads of mice kept at an air temperature of 20 C. At air temperatures of 15 and 25 C, bacillary multiplication was slightly slower; at 10 and 30 C, distinctly slower; and at 4 and 35 C, no baci...
متن کاملEffect of Temperature and Light on Germination Characteristics of Japanese Morning Glory (Ipomoea nil): Determination of Cardinal Temperatures of Germination
DOR: 98.1000/2383-1251.1398.6.115.11.1.1575.1610 Extended Abstract Introduction: In recent years, Japanese morning glory has been recognized as a new weed in some soybean cultivation areas in the Province of Golestan. Japanese morning glory, an annual herbaceous plant, belongs to Convolvulaceae family. Germination is the first step in the competitiveness of a weed in an ecological niche. ...
متن کاملstudy of different techniques for breaking dormancy and optimum temperature for germination of russian knapweed (acroptilon repens)
abstract increased knowledge of russian knapweed biology would facilitate development of an optimum control program. to examine germination characteristic of this weed, several experiments were conducted in weed research department, plant pest and diseases research institute of tehran during 2003. first experiment was a factorial with 3 replications to break seed dormancy of this weed. first fa...
متن کاملPhotocontrol of the germination of onoclea spores: v. Analysis of germination processes by means of temperature.
The physiological nature of photoinduced germination of Onoclea sensibilis L. spores was investigated by temporarily applying a range of temperatures, particularly 40 C, before and after short light treatment. Controls were germinated at 25 C.The preinduction phase, during which photosensitivity is maximally developed in the dark, is sensitive to temperature. Treatment at 40 C for 8 or more hou...
متن کاملPhytochrome and Seed Germination: VI. Phytochrome and Temperature Interaction in the Control of Cucumber Seed Germination.
Phytochrome control of cucumber seed germination is temperature-dependent. A prolonged exposure to radiation from broad spectrum far red sources (Pfr/P = 0.05 to 0.07) prevents germination at temperatures below 20 C. Above 20 C there is no inhibition and it appears as if there is an escape from phytochrome control. However, radiation from a monochromatic, narrow band 730 nanometer source (Pfr/P...
