Exposure to high temperatures (heat stress) causes reduced yield in tomatoes (Lycopersicon esculentum), mainly by affecting male gametophyte development. Two experiments were conducted where several tomato cultivars were grown under heat stress, in g

Mannitol, a six carbon sugar alcohol, has heretofore received little attention from plant scientists, despite its wide distribution in nature. However, recent findings concerning the biochemistry and physiology of higher plants indicate that species

Foliar raffinose and sucrose concentrations in eastern white pine (Pinus strobus L.), eastern redcedar (Juniperus virginiana L.), Leyland cypress (xCupressocyparis leylandii Dallim.), and Virginia pine (Pinus virginiana L.) were measured monthly over

Two cultivars of greenhouse tomato (Lycopersicon esculentum Mill.) were grown with ambient or 1000 µl CO2/liter during Jan.-June 1987 and 1988. In both years, CO 2-enrichment increased foliar deformation and foliar starch, but during the season, fol

Yield increases observed among eight genotypes of tomato (Lycopersicon esculentum Mill.) grown at ambient CO(2) (about 350) or 1000 microliters per liter CO(2) were not due to carbon exchange rate increases. Yield varied among genotypes while carbon

Increasing salinity of agricultural soils may ultimately limit the sustainability of food production in some areas of the world. Work from our laboratory and the labs of others demonstrates that mannitol, a six-carbon sugar alcohol, is important as a

Containerized, 2.5-year-old, hedged stock plants of four, full-sib families of loblolly pine (Pinus taeda L.) were fertilized daily with a complete nutrient solution containing 10, 25, 40, 55, or 70 ppm N, which resulted in a range of stock plant sol

The effects of genetic line, curing, length of 1°C storage, and length of subsequent 21°C storage on hardcore in sweet potato roots (Ipomoea batatas) were studied. Both incidence (percent roots affected) and severity (amount of affected tissue per

Summary Galactinol synthase, UDP-D-galactose:inositol galactosyltransferase, was purified 105-fold from leaves of Cucumis sativus L. Mg ++ was unable to substitute for Mn ++ in stimulating activity. Low levels of Mn ++ were much more stimulatory at p
