Water 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 کاملPhenolic glycosides and condensed tannins in Salix sericea, S. eriocephala and their F1 hybrids: not all hybrids are created equal.
The performance of hybrids depends upon the inheritance and expression of resistance traits. Secondary chemicals are one such resistance trait. In this study, we measured the concentrations of phenolic glycosides and condensed tannins in parental and F1 hybrid willows to examine the sources of chemical variation among hybrids. S. sericea produces phenolic glycosides, salicortin and 2'-cinnamoyl...
متن کاملThe Genetic Basis for Variation in the Concentration of Phenolic Glycosides in Salix sericea" Clonal Variation and Sex-based Differences
-Many members of the Salicaceae produce phenolic glycosides, and the concentrations of these are known to vary among plants. We determined whether the concentration of two phenolic glycosides, salicortin and 2'-cinnamoyl salicortin, varied among clones of Salix sericea and whether this variation was due to the sex of the plant. We tested 16 clones, seven male and nine female, for variation in g...
متن کاملCytotoxic alkaloids from Houttuynia cordata.
Six bioactive alkaloids, aristolactam B(1), piperolactam A(2), aristolactam A(3), norcepharadione B(4), cepharadione B(5) and splendidine(6) were isolated by bioactivity-guided fractionation of a methanolic extract of the aerial part of Houttuynia cordata. Several of them exhibited significant cytotoxicity against five human tumor cell lines (A-549, SK-OV-3, SK-MEL-2, XF-498 and HCT-15) in vitro.
متن کاملAnxiolytic effect of hydroethanolic extract of Drymaria cordata L Willd.
Drymaria cordata hydroethanolic extract (DCHE) at 25, 50 and 100 mg/kg (p.o.) was administered to study anxiolytic effect. Different models for anxiolytic activity viz. Hole board, Open field, Elevated plus maze, Light/dark exploration model were used. In the hole board model, there was dose dependent and significant increase in the numbers of head pokes and the time of head dipping in the trea...
