Abstract
|
|
|
|
Initiation of root primordia and physiochemical changes according to low temperature pretreatment were analyzed in cuttings of carnation cv. Desio. Sucrose content markedly increased at 5℃ for 2wks, but starch and total carbohydrates decreased with low temperature pretreatment. Activity of auxin-like substances in stem tissue of carnation were increased when stem tissue was stored at 5℃. New protein band of 45 kDa, between 45 kDa and 55 kDa were biosynthesized after stem tissue has been stored at 5℃. Root primordia were initiated and differentiated from pericycle parenchyma cells after low temperature and plant growth regulator pretreatment.
