THE INDUCEMENT AT THE ROOTEDNESS PROCESS OF KERRIA JAPONICA CUTTING USING RADISTIM TYPE BIOACTIVE SUBSTANCE
Journal Title: Natural Resources and Sustainable Development - Year 2011, Vol 1, Issue 1
Abstract
Kerria japonica is a shrub cultivated as decorative plant for its small, lasting and shining leaves,oval-elongated (3-5 cm/2,5-4,5 cm), with short tail (0,5-1,5 cm) and for the various colored sepals (pink, red, violet)gathered around the yellow flowers with no decorative value (Cuisance P; 1992). In present it is known as a decorative plant cultivated in field. In areas with less favorable climate conditions where the minimal temperature goes down during winter below the resistance limit, they are cultivate in pots placed outdoor during the summer and indoor during the cold season (Thome S; 2002). In our country Kerria japonica is no very spread because of the shortage of cutting caused by the low rate of multiplication. In order to increase the efficiency of multiplication on vegetative way, between 2009-2011, in the green houses from Oradea we have wached over the Kerria japonica cuttings rootedness process using stimulating substances of Radistim type.
