Plant growth and development is affected by various environmental stresses such as drought, salinity, and suboptimal temperatures. During the seed germination and seedling growth stages, plants are the most vulnerable to stresses ( Almansouri et al

, ecosystems in which several congeners of new jersey tea are native, are dependent on fire for renewal and regeneration ( Keeley, 1991 ; McMillan Browse, 1994 ), which is reflected in the observation that seed germination of several ceanothus ( Ceanothus spp

Germination of stratified seed was highest for immature fruit of red elder (Sambucus pubens Michx.), harvested in early August, and for fruit of Tatarian honeysuckle (Lonicera tatarica L.), harvested in mid-August. Neither specific gravity nor moisture content of the fruit were related to seed germination.

Viola tricolor seed were exposed to aerated solutions of water or 300 or 400 mM NaCl for 0, 2, 4, 6, or 8 days. After priming treatments, seed were air dried, placed on moist filter paper in petri dishes, and set in dark growth chambers at 18 or 30°C for germination. priming for 6 days in water increased germination of `Crystal Bowl Yellow' seed from 80 to 88% when germinated at 30 °. Untreated seed germination was 92% at 18°. Priming for 6 days in 300 mM NaCl improved germination of `Majestic Giant Blue' seed from 57 to 76% when germinated at 30°. Untreated seed germination was 80% at 18°. These data indicate that seed priming could be used to improve summer germination of a cool season annual. Priming increased germination at the higher than optimum temperature (30°) to levels similar to that for the optimum temperature (18°). However, the best priming solution depended on the cultivar.
