Field, greenhouse, and growth chamber experiments were conducted to determine the effects of different burial treatments on photosynthesis (carbon dioxide exchange rate), chlorophyll-a fluorescence, leaf area, biomass, leaf thickness, total chlorophy

A greenhouse study was conducted to determine the effects of sand burial on seed germination and seedling emergence of Cirsium pitcheri, a threatened species along Lake Huron sand dunes. In October 1996, seeds of C. pitcheri were sorted into three gr

More than 50 years ago it was proposed that zonation of major plant species on coastal dunes was determined by salt spray. Here, we argue against this hypothesis because (i) salt concentrations rarely exceed toxic levels; (ii) high precipitation in t

Sand movement is a predominant feature of mobile coastal and lake-shoreline sand dunes. Plants growing in these environments are able to withstand and survive periods of burial by sand. Although mosses are important dune stabilizers in temperate dune

A greenhouse study was conducted to determine the effects of increasing concentrations of salt (NaCl) solutions applied to the soil containing mycorrhizal and non-mycorrhizal plants of the leguminous species Strophostyles helvola (L.) Ell. The dry we

Studies on the survival and establishment of seedlings in coastal and lacustrine sand dune systems suggest that nutrient deficiency, lack of moisture, sand accretion, salt spray and predation are probably the most important limiting factors. Seedling

White cedar (Thuja occidentalis L.) plants sprayed with deicing salt and kept at 91–100% relative humidity even for 1 day exhibited necrosis of foliage. However, sprayed trees kept at a relative humidity of 50–70% for 20 days showed only slight y

Greenhouse studies were conducted to study the competition between soybeans [Glycine max(L.) Merr. ‘Vansoy’] and barnyardgrass [Echinochloa crus-galli(L.) Beauv.]. The competition was initiated or terminated when soybeans were 2, 3, 4, 5, 6, 7, 8
