It has been made evident by the experiments recently published by one of us, that the amount of carbon-dioxide assimilation which a leaf is actually performing, or is capable of performing, is profoundly affected by the temperature of the assimilating cells. Neglect of this factor has been a fruitful source of confusion in attempts to estimate the effect of different intensities of light upon the process of assimilation.

Experimental Researches

That the activity of a plant in the function of assimilation is influenced to a certain extent by the temperature to which it is subjected, has long been recognised, but, in spite of the universal acceptance of this principle, comparatively little detailed study has been undertaken in confirmation of it. The present investigation was undertaken at the suggestion of Dr. F. F. Blackman and has been carried out in his laboratory. The problem proved to be much more complex than was anticipated and I have to acknowledge, with great pleasure, my indebtedness to Dr. Blackman for frequent valuable advice and several important suggestions.

Exchange Parameters

The effects of NAA, BA, or Accel on CO2 assimilation of shoot leaves of mature bearing Redchief `Delicious' and `Empire' apple (Malus ×domestica Borkh.) trees were evaluated over two seasons. BA at 50 mg·L-1 did not significantly affect any of the gas-exchange parameters measured. NAA (15 mg·L-1) consistently suppressed CO2 assimilation rate (from ≈10% to 24% below that of the control). This suppression was NAA-concentration dependent, continued for >15 days after treatment, and was completely overcome in `Empire', but only partially or not at all in `Delicious' when BA was combined with NAA. These results are discussed in relation to fruit thinning and NAA-induced inhibition of fruit growth in spur-type `Delicious'. Chemical names used: 2-(1-napthyl) acetic acid (NAA); N-(phenyl)-1H-purine-6-amine (BA); BA + gibberellin A (GA)4+7 (Accel).

Plants are balanced systems that integrate processes of carbon fixation and uptake of water and nutrients to optimize resource acquisition. Response of Juniperusoccidentalis Hook. to reductions in above- and below-ground tissue was measured to determine effects on carbon dioxide assimilation, leaf conductance, intercellular carbon dioxide, xylem water potential, foliage nutrient concentration, aboveground growth, water-use efficiency, and potential photosynthetic nitrogen-use efficiencies. Approximately 50% of the old foliage was removed and lateral roots were severed at the canopy edge in early April 1988; physiological processes were measured during three periods in the summer of 1988. Foliage removal increased rates of carbon dioxide assimilation and photosynthetic nitrogen-use efficiency, but neither increased growth nor improved water status or nitrogen concentration of remaining foliage. Cutting lateral roots reduced assimilation, leaf conductance, foliage nitrogen concentration, branchlet elongation, water-use efficiency, and photosynthetic nitrogen-use efficiency. By late August, juvenile and small-adult J. occidentalis in the cut-top treatment had compensated for foliage removal by reestablishing patterns of water-use efficiencies similar to those of control plants, which may indicate that an overall metabolic control was functioning to regulate the balance between carbon dioxide assimilation and water loss. Cutting lateral roots had a more lasting effect on efficiencies; by late August, juveniles and small adults still had significantly lower water-use efficiencies than controls.

Cherry Laurel

The primary general relation between external supply of carbon dioxide and rate of carbon assimilation in light by the green cells of plants has been investigated by many plant physiologists, and in general, so long as the assimilation is appreciably below the maxima permitted by the light intensity employed and by the temperature of the green cell, the relationship may be held to approximate to direct proportionality between rate of assimilation and external concentration (partial pressure) of CO 2 . The case seems most clear for water plants, where a direct proportionality has been demonstrated by Blackman and Smith, 1911 (2), for Elodea. The experiments of Brown and Escombe, 1902 (4), with land leaves, at concentrations of CO 2 up to seven times that of ordinary air, point in the same direction, and although the results of later workers with land leaves (Boysen-Jensen, 1918 (3), and Lundegardh, 1921 (7) ), do not in some other respects conform to the simple type shown by the Elodea results, yet, so far as the direct proportionality between CO 2 concentration and apparent assimilation is concerned, the position is rather strengthened than otherwise.
