LIGHT INTENSITY AS IT AFFECTS GROWTH AND BRANCHING OF THREE WOODY PLANT SPECIES (HETEROPHYLLOUS, EUONYMUS, BIFURCATION RATIO)

Gary W. Knox Purdue e-Pubs (Purdue University System) 1984

Other claims from this paper (16)

Intervention effect Low light produced more leaf primordia in terminal buds of Euonymus.
Association Euonymus bud primordia number did not correspond to next-year shoot leaf number.
Intervention effect Euonymus in full sunlight had the greatest stem and root soluble sugars and starch.
Intervention effect Light did not influence bud morphology in privet.
Intervention effect Light did not influence stem and root soluble sugars and starch in privet.
Intervention effect Light did not influence bud morphology in viburnum.
Intervention effect Light did not influence stem and root soluble sugars and starch in viburnum.
Intervention effect Viburnum dry weights were greatest under 53%, 70% and 100% light after one season.
Association Prior-year light strongly affected second-season plant dry weight.
Intervention effect Viburnum grown in full sun in 1982 had the greatest dry weights in 1983.
Intervention effect Privet shaded in 1982 had the greatest shoot dry weights in 1983 regardless of 1983 light.
Intervention effect Full sun in 1982 increased viburnum branch number, branch length and internode length in 1983.
Intervention effect Privet in 100% light in 1983 was more branched than shaded plants.
Observation Willowwood viburnum tolerated 53% to 100% light.
Intervention effect Light intensity did not significantly affect Euonymus growth.
Recommendation The authors suggest varying light to improve growth and branching and shorten time to sale.
