At completion of 90 days in Trial 1, all shaded Osage orange seedlings were significantly taller than seedlings exposed to less or no shade.
It can be inferred from these findings that Osage orange will tolerate increasing shade without detriment to above-ground seedling biomass.
Generally, treating Osage orange seedlings with increased shade resulted in increased growth and above-ground biomass, while decreasing below-ground biomass.
Overall, intercropping Osage orange with soybean tended to decrease plant growth in Osage orange (Table 4).
Mean plant height of Osage orange differed significantly (P [less than or equal to] 0.
Generally, experimental data showed less overall plant mass and lower heights for Osage orange seedlings grown in the third row, or northern facing edge, of blocks three and six (Figure 1).
Although results from the field trial are somewhat contradictory to results obtained in the greenhouse trials, decreased biomass in Osage orange seedlings which were heavily intercropped is more likely a factor of competition for nutrients and water and not directly due to shading.
Based upon results obtained from both the greenhouse controlled environment shading trials and the field intercropping experiment, it can be reasoned that Osage orange seedlings will tolerate increased shade amounts without detriment to overall biomass.
Osage orange (Maclura pomifera): History and economic uses.
Cedarburg, WI, furniture designer/craftsman Charles Radtke uses Osage orange and mulberry, a wood it closely resembles, in some of his custom pieces.
Osage orange is unique in that it is monotypic, a genus with only one species, (Maclura pomifera) although at one time there were many species of Maclura.
