Lonicera japonica is a climbing plant which can grow up to 10 m in length; the young stems are often hairy, while mature stems display a brownish bark and are empty on the inside, the leafs are oval and long, the flowers are known for their appealing perfume, white and yellow in colour, and the fruit is small and black. It is a persistent climbing plant, which offers an impressive bouquet of colour, flowers and an inviting perfume, which made it famous in our country as well as abroad.
During the study, two rooting substances were used, with 4 sublayers and 3 different cutting preparation periods, monitoring their influence on the rooting rate of Lonicera japonica cuttings, using the rhizogenic substances Atonik and Radistim. According to the research we carried out, one may observe, that the three studied factors had a real and distinctly significant influence on the rooting of the Lonicera cuttings, on the background of an environmental conditions homogeneity at the level of the experimental device and a cumulative factor action of 88.70 %. For a wider research, we also monitored the influence of cutting length on the rooting rate for the Lonicera japonica cuttings. The sublayers had a significantly higher effect (54.64 %) on the variability of this characteristic, as compared with the stimulator effect (17.74 %) and that of the periods (4.21 %). Also, the combined simple and double factor effects manifested statistically insured influences on the variability of cutting rooting for this species, higher in the case of stimulator x period interactions (5.42 %), respectively stimulator x sublayer interaction (2.95 %). Given the unilateral effect of cutting size, the average rooting percentage registered an amplitude of 41.25 % presenting values between 25.83 % in the case of 15 cm cuttings, respectively 67.08 % in the case of 10 cm cuttings, on the background of a very high variability (s%=43.01) between results pertaining to the three cutting categories. |
