Autumn-olive

Significantly more Nitrobacter inhabited the soil in plots of walnut mixed with European alder than in plots of walnut mixed with autumn-olive or walnut alone. Apparently juglone concentrations were not sufficient to inhibit populations of these nitrifying microorganisms. 

To gain more understanding of the European alder decline and because of our concern about the future growth of black walnut planted with nitrogen-fixing species, a study was initiated to measure soil juglone concentration and to estimate the number of Nitrobacter and Nltrosomonas bacteria in a black walnut plantation containing plots of black walnut alone and in mixture with European alder and autumn-olive. 

The mean juglone concentration in soil beneath plots of autumn-olive/ black walnut was significantly lower than in soil beneath European alder/black walnut and black walnut-alone plots (Table I). Juglone concentrations also differed with sampled depth (Table I). Significantly higher concentrations were present at the 0-8 cm depth than at lower depths. 

Mean organic matter was greatest in the European alder/black walnut treatment, followed by the walnut-alone and autumn-olive/black walnut treatments (Table III). The mean pH was lowest in the autumn-olive/black walnut treatment, followed by the European alder/black walnut and walnut-alone treatments. 

The almost bare to sparsely covered understory under autumn-olive in autumn-olive/black walnut plots has been attributed to reduced light intensity caused by the dense shade. The understory conditions rapidly approach those of a hardwood "forest" compared to the open European alder/black walnut and walnut-alone plots (38). Thus, the autumn-olive shorten the time it would normally take old-field conditions to disappear (37). The overall height of autumn-olive and the understory plot conditions have not changed in the last 4 or 5 years, while growth of the black walnut has continued at an improved rate (39). 

In summary, there is little reason to be concerned about allelopathy in mixed plantations where walnut is grown for timber as the harvested crop. Allelopathy does appear to be a factor to consider before planting European alder as a nurse crop with black walnut. Black walnut has had no apparent effect on the autumn-olive but is probably responsible for the decline and mortality of the European alder. These results present interesting possibilities for future research on the plant/soil/microbial relationships related to the metabolism of aromatics.

Some species, such as ash, have seasonally deciduous leaves, which fall off in the autumn after they become non-functional. Other species, such as olive, have persistent leaves, in that there are always some leaves attached to the tree, even when they are no longer functional. In most species in this family, the leaves arise opposite to one another on the stem. The leaves of some species, such as lilac and golden bell, are simple in that they consist of a single blade. The leaves of other species, such as ashes, are compound, and are composed of many separate leaflets. 

The olive tree has persistent leaves, blooms in the spring, and produces mature fruits in the late autumn or winter. The unripe fruits are green and bitter, while ripe fruits are purple to black in color. The bitterness of the green, unripe fruits can be removed by soaking them in a solution which is alkaline (high pH) or is saturated with salt. Once the bitterness has been removed, green olives are typically pickled in a salt solution for later eating. 

Plants may also play a role in the transfer of compounds to the atmosphere. Eight species (soybean, barley, and lettuce Russian olive, autumn ohve, green ash, hybrid poplar, and honeysuckle) were grown hydroponically in a solution...

In autumn necrotic spots found on leaves then spreads to stems. Foliage turns olive-green and then in early spring turns black and eventually dies. The root can also die. 

The Benecol range now includes an olive oil variant, launched in autumn 2000, as well as the Original and Light (40% fat) versions in its spreads portfolio. The manufacturer has also extended the brand into other areas, including cream cheese spreads (initially launched with the fat spreads, but since reformulated and relaunched), as well as yoghurts and snack bars -opening up a unique market sector that McNeil describes as cholesterol management .
