Sucker Free Sunday €? Issue 28



I loved the music at suckerfree. This restaurant doesn't remind me of a soul food restaurant, but it has a high end sports bar feel. The people who work at this place are from Louisiana. The food was very diverse and filled with flavor. The bartenders are so nice I wonder if I could hangout with them later.


Age of wood is the most important factor in rooting quaking aspen cuttings. With rare exceptions, the species roots poorly from woody stem cuttings, even when treated with indolebutyric acid (IBA). However, newly initiated shoots can usually be induced to root by dipping in IBA or other commercially available rooting powders. These softwood stem cuttings should be taken from actively growing shoots except during the period of extremely rapid mid-season elongation (14,63,78). Propagation by excising succulent young sucker shoots from root cuttings is easily accomplished by treating the shoots with IBA and growing them in a suitable medium in a misting chamber until rooted, in about 2 to 3 weeks (62). Quaking aspen scions can be grafted onto balsam poplar (Populus balsamifera), willows (Salix spp.), or bigtooth aspen (P. grandidentata). Quaking aspen plantlets have been produced by tissue culture (81).

Recently, viruses have been detected in a few quaking aspen clones. Once trees in the clone are infected, regeneration by suckering maintains the infection, which is then impossible to eliminate except by artificially culturing virus-free tissue. The full extent and seriousness of viruses in aspen is unknown but decline of some clones has been attributed to them in both the East and the West.


Early spring frosts may kill new leaves and shoots and, when especially severe, some of the previous year's shoots. Overwinter freezing can cause frost cracks. Strong wind can uproot or break mature aspen and even moderate wind can crack the bole of trees with lopsided crowns. Hail can bruise the bark of young aspen and, in severe storms, kill entire sapling stands. Aspen suffers little from ice storms or heavy wet snow, except when in leaf. Snow creep on steep slopes can bend or break aspen suckers as tall as 1.2 in (4 ft) (28).


The vegetative cells of aspen, as well as those of nearly all aspen hybrids, contain 19 pairs of chromosomes. A number of triploid aspen (with three sets of chromosomes rather than the normal two) have been located in Utah, the Lake States, and Colorado. A few albino aspen seedlings have been observed, as have two albino aspen suckers, which were thought to result from a somatic mutation in aspen root tissue (30,37,78).
