Seed quality is a complex concept, consisting of a number of components that each
represent different physiological principles, eg germinability, viability, vigour and storability …

The objective of this study was to quantify water volume and nutrient content leached during
propagation of herbaceous cuttings in commercial greenhouses. Nutrient concentrations in …

Commercially grown black spruce (Picea mariana) seedlings in NW Ontario were used to
evaluate (i) dormancy in terms of freezing tolerance and (ii) photosynthetic efficiency …

Temperature and chlorophyll fluorescence characteristics were determined on leaves of
various horticultural species following a dark adaptation period where dark adaptation …

The practice of stock plant etiolation, whereby dormant plants are grown under severely
restricted light levels and then allowed to green up while shoot bases remain etiolated …

The effect of storage temperature on the longevity of unrooted poinsettia (Euphorbia
pulcherrima 'Prestige Red') cuttings was examined. Unrooted cuttings were harvested from …
