Endogenous 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 کاملSalix × meyeriana (= Salix pentandra × S. euxina)―a forgotten willow in Eastern North America
Salix pentandra L. is a boreal species native to Europe and western Siberia. In North America it is considered to have been introduced to about half of the US states (Argus 2007, 2010). In Massachusetts it is reported from nine of the fourteen counties (Sorrie & Somers 1999). Even though this plant may have been introduced to the US and Canada, its naturalization in North America appears to be ...
متن کاملPolymorphism and Divergence in Two Willow Species, Salix viminalis L. and Salix schwerinii E. Wolf
We investigated species divergence, present and past gene flow, levels of nucleotide polymorphism, and linkage disequilibrium in two willows from the plant genus Salix. Salix belongs together with Populus to the Salicaceae family; however, most population genetic studies of Salicaceae have been performed in Populus, the model genus in forest biology. Here we present a study on two closely relat...
متن کاملWater availability alters the relative performance of Salix sericea, Salix eriocephala, and their F1 hybrids
Seedlings of Salix eriocephala Michx., Salix sericea Marsh., and their F1 hybrids were tested for their growth under contrasting water conditions. One-year old seedlings were grown in pots and subjected to one of two experiments, a scheduled-watering experiment (watered every 1, 4, 8, or 12 days) or a dry-down experiment (no watering after an initial period without water limitation). In the sch...
متن کاملBioactive secondary metabolites from Salix tetrasperma Roxb.
Column chromatography of the light petroleum fraction from the methanolic extract of the stem bark of Salix tetrasperma Roxb. (Salicaceae) resulted in the isolation of beta-sitosterol acetate, friedelin, 3beta-friedelinol, beta-amyrin, beta-sitosterol, beta-sitosterol-O-glucoside in addition to palmitic acid. From the dichloromethane fraction of the leaves, catechol and tremulacin were isolated...
