    Notes:
    Soil entrapment by plant tissue is often ignored when the tissue is analyzed. This leads to errors in interpretation of results. Plant tissue samples were taken from vegetables grown in experimental field plots in Norfolk, VA, Riverhead, NY, and Geneva, NY. At harvest, plant tissues were washed with deionized water, cut into small pieces, oven dried (VA) or freeze dried (NY), ground to pass a 0.0841-cm stainless steel screen and stored in glass bottles. The surface 15 cm of each soil was sampled. Subportions of tissue and soil were analyzed for a number of elements by inductively coupled argon plamsa emission spectrometry (ICP-ES) and electrothermal atomic absorption (ETAA). Titanium (Ti) concentrations in the soil and plant tissue were used as a measure of soil inclusion. As much as 76% of the Al, 100% of the Cr, and 70% of the Fe in the vegetable samples could be accounted for by soil particulate inclusion by the plant tissue during its growth.

    Abstract Differential thermal analysis (DTA) was used to measure the freezing temperature of nine species of red brown intertidal macroalgae from the coast of Maine, USA in 1991. Using slow and rapid cooling rates approximating those found in the field for Ascophyllum nodosum (L.) Le Jol. we found that, for a given rate, the freezing points of all species were similar: -7.06 to -8.02°C for slow cooling (ca. 0.25°C min-1) and -3.42 to -4.56°C for rapid cooling (ca. 5.0°C min-1). In the low shore species, Fucus evanescens C. Ag., photosynthesis was inhibited to a greater extent when plants were frozen or thawed rapidly than after slow freezing or thawing. However, in the upper shore species, F. spiralis (L.), photosynthesis recovered rapidly and completely regardless of freezing rate. Rapidly frozen F. evanescens also experienced greater loss of plasmalemmal integrity, evidenced by a greater loss of cellular contents on re-immersion, than those frozen slowly. Light-limited photosynthesis following freezing was more severely inhibited than light-saturated photosynthesis. Respiration was generally enhanced immediately after freezing, but then declined to rates below those of unfrozen controls within 2 h following re-immersion, with control rates of respiration being achieved after a 24 h recovery period. Our data suggest that the physiological consequences of winter emersion at sub-zero temperatures may vary widely between individual plants of freezing-susceptible species, due to the wide variations in freezing rate associated with microhabitat effects.
