ROOT CUTTINGS FOR ROADSIDE SLOPE STABILIZATION - INTERIM REPORT

THE PRINCIPAL REQUIREMENT IN ESTABLISHING HIGHWAY PLANTINGS IS SPEED. HOWEVER, IN MANY AREAS WOODY ORNAMENTAL PLANTS ARE MORE EFFICIENT THAN GRASS. AT PRESENT MOST SUCH PLANTS ARE EMPLACED ONLY AFTER SEVERAL SEASONS' GROWTH. IN THE CASE OF SLOPES, OTHER MEANS OF ESTABLISHMENT MUST BE USED. DIRECT SEEDING AND USE OF YOUNG SEEDLINGS HAVE BEEN TRIED, BUT ALMOST NO ATTEMPTS HAVE BEEN MADE AT MASS PROPAGATION WITH ROOT CUTTINGS, IN SPITE OF THE FACT THAT THIS METHOD IS PROBABLY THE LEAST EXPENSIVE AND MOST SIMPLE ONE, CAN BE ACCOMPLISHED BY MECHANICAL MEANS, AND IS THE BEST ONE FOR INCREASING PLANTS THAT DO NOT BEAR RELIABLE SEED. WITH THE FOREGOING IN MIND, EXPERIMENTS WERE DESIGNED TO EVALUATE THE FOLLOWING: (1) FEASIBILITY OF STABILIZING ROADSIDE SLOPES WITH WOODY ORNAMENTAL PLANTS PROPAGATED FROM ROOT CUTTINGS, (2) RESPONSE OF SPECIES OF PLANTS COMMONLY PROPAGATED BY ROOT CUTTINGS UNDER HIGHWAY CONDITIONS, (3) RATES OF PLANTING OF ROOT CUTTINGS NECESSARY FOR SUFFICIENT SLOPE COVER, (4) OPTIMUM PLANTING DATES FOR PROPAGATION BY ROOT CUTTINGS, AND (5) USE OF GROWTH REGULATORS FOR INDUCTON OF ROOTS ON ROOT CUTTINGS. THE DESIGN AND RESULTS OF THREE EXPERIMENTS ARE REPORTED.
