The most conclusive method to identify ABA is by combined gas chromatography-mass spectrometry (20, 29, 33). Little et al. (34) monitored the current of a single ion, viz, that of the base peak, m/e 190, in the mass spectrum of Me-ABA, for quantitative determinations of ABA in the cambium of Picea sitchensis. However, few laboratories are able to carry out... [Pg.102]

Specimens of Sitka spruce Picea sitchensis) and Glehn spruce Picea glehnii) were modified by eight kinds of chemical treatment. Weight percent gain (WPG) resulting from each chemical treatment was determined based on the over-dry weight of the specimen before and after treatment. [Pg.314]

A review of silvicultural systems for Picea sitchensis in the UK (Macdonald and Hubert, 2002) provides further examples of product push with low valued pallets, packaging and fencing absorbing two-thirds of production - and Sitka spmee is classified as non-durable and resistant to treatment. [Pg.153]

Radial permeability is not as well understood as longitudinal or tangential permeability and indeed the tree has no path for - or interest in - radial flow except within ray tissue. However, after drying (and pit aspiration) the minimal radial permeability in some species can exceed tangential permeability. The greater radial air-dry permeability for Pinus sylvestris compared to either Picea sitchensis or Pseudotsuga menziesii is attributed, in part, to the pine having many more ray tracheids. [Pg.262]

The occurrence of brassinosteroids in gymnosperms has been reported from conifers. Yokota ef al. isolated typhasterol ( 2-deoxycastasterone ) from pollen of Japanese black pine ( Pinus thunbergii ) (38) and identified castasterone and typhasterol from shoots of sitka spruce (Picea sitchensis ) (39). Kim ef al. also identified castasterone and brassinolide from cambial scrapings of Scots pine (Pinus silverstris ), using a modified dwarf rice lamina inclination assay which showed a synergistic response of brassinosteroids with indole-3-acetic acid (40). [Pg.33]
