Answer: I spent some time searching the web, but didn't come across anything appropriate. You might try, though. I searched using the words 'plant', 'root', 'growth' and 'temperature'.<br><br>I think your best bet would be to find a plant physiology textbook--perhaps your school library has one. Probably the most research has been done on the optimum germination temperature for different types of seeds, so this would be a good place to start. You might search the web with thisin mind.<br><br>This site has a little information:<br><br>http://www.ag.usask.ca/cofa/departments/hort/hortinfo/misc/seeds3.html<br><br>This one is about taking cuttings; try to see if the same organization has information about seeds:<br><br>http://hammock.ifas.ufl.edu/txt/fairs/10611 <br>This address is for a Plant Propagator's society: http://www.rhombus.net/nga/newanswer.html?qnum=14967 <br>Finally, you may be able to make some inferences about the effect of temperature by thinking about the natural environment of the plant. Is it tropical, and adapted to warm soils? Temperate, and adapted to soils of varying temperatures? What stimulates roots to grow in the first place? Lots to think about!
