Partial flooding enhances aeration in adventitious roots of black willow (Salix nigra) cuttings.
Black willow (Salix nigra) cuttings are used for streambank stabilization where they are subjected to a range of soil moisture conditions including flooding. Flooding has been shown to adversely impact cutting performance, and improved understanding of natural adaptations to flooding might suggest handling and planting techniques to enhance success. However, data assessing the root aeration in ...
متن کاملPropagation of Thornless Blackberries Utilizing Adventitious Shoots from Root Cuttings
Studies were conducted in early 2003 to determine the effect of root source and length on yield of adventitious shoots and plant yield from root cuttings of Arkansas-developed thornless blackberries. In the first study, roots from ‘Arapaho’ and ‘Apache’ plants grown in an aboveground bed containing commercial potting soil were compared to field-grown roots. Bed-grown roots averaged 6.9 shoots p...
متن کاملEndogenous Gibberellins in Elongating Shoots of Clones of Salix dasyclados and Salix viminalis.
Elongating shoots of rapidly growing clones of Salix viminalis L. (clone 683-4) and Salix dasyclados Wimm. (clone 908) harvested in early August were analyzed for endogenous gibberellins (GA). Distribution of GA-like activity, determined by Tan-ginbozu dwarf rice microdrop bioassay after reverse phase C(18) high performance chromatography, was similar for both species. For S. dasyclados, combin...
متن کاملAssessment of factors affecting adventitious shoot regeneration from in vitro cultured leaves of apricot.
Relatively high percentages of adventitious shoot regeneration have consistently been obtained from leaves of some apricot cultivars. For the cultivar 'Helena', explants from the proliferation medium were more reactive than those from the elongation medium. The best results were obtained with thidiazuron (TDZ). When 6-benzylamino-purine (BAP) was used instead of TDZ, the regeneration percentage...
متن کاملEffects of photooxidation on membrane integrity in Salix nigra seeds.
BACKGROUND AND AIMS Salix nigra seeds are desiccation-tolerant, as are orthodox seeds, although in contrast to other orthodox seeds they lose viability in a few weeks at room temperature. They also differ in that the chloroplasts of the embryo tissues conserve their chlorophyll and endomembranes. The aim of this paper was to investigate the role of chlorophyll in seed deterioration. METHODS S...
