    Notes: Trehalose, Resipration and Photosynthesis in the Fern Ophioglossum. A new Type of Shade-Leaves.—Trehalose has been identified in the leaf-blades, sporehouses, stems and rhizomes of the fern Ophioglossum vulgatum by paper chromatography. The leaf-blades represent a hitherto undescribed type of shade-leaf. Just like normal shade-leaves, they have a low respiratory activity ∼0.2–0.3 mg CO2 per 50 cm2 leaf-blade (one side only) and hour at 20°C and low maximal photosynthesis: 2–2.7 mg CO2 per 50 cm2 leaf-blade (one side only) and hour at 20°C and a CO2-pressure of 0.25 mm Hg and a light intensity of 20,000 lux. But in contrast to the hitherto described type of shade-leaves, the area per 1 g fresh weight is that of typical sun-leaves which is 35–50 cm2 (one side only) per 1 g fresh weight. The large area weight is connected with particularly low dry matter content ∼10–11 per cent in the leaf-blades; this indicates that the material is a kind of semisucculent shade-leaf.

    Notes: Nitrogen Content in Leaves from Psychotria with Nitrogen-Fixing Endophytes. — Leaves from Psychotria calva with bacteria along the midrib did not contain more nitrogen than leaves from the surrounding trees. This indicates probably that the nitrogen fixing activity of the endophyte is small or zero.

    Respirationsintensität in Stäinmen, Zweigen und Blältern von Laubbäumen im tropischen Regenwald und in temperierten Wäldern (1969)

    Notes: Respiratory Activity in Stem, Branches and Leaves of Evergreen Trees in Tropical Rain Forest and of Deciduous Trees in Temperate Climate.— Reduced to the same temperature, the respiratory activity of different parts of tropical rain forest trees and of corresponding parts of temperate deciduous trees is approximately the same. In particular, the leaf-blades of Danish deciduous trees and of tropical rain forest trees from the lowland of Côte d'Ivoire (57° north. lat.) have nearly the same respiratory activity at 20°C: the blades of the extreme shade leaves about 0.1 mg CO2, those of the extreme sun leaves about 0.8 mg CO2 per 50 cm2 (one side only) per hour at 20°C. This is in accordance with the fact that the blades of shade leaves, respectively Sim leaves, of the tropical rain forest trees are built in the same way as the blades of deciduous trees in our temperate climate. The respiratory activity shows that they have the same “concentration” of living cells, the same “concentration” of active plasma.The respiratory activity of trunk and branches depends mainly on three factors: diameter of the stem-section or branch-section, nutritional condition, and temperature. The respiratory activity of trunk and branches of hardwoods in temperate climate is also dependent on the season. The estimations on stems and branches from the temperature trees were made In July–August. There was in most cases a remarkable agreement in respiratory activity between temperate and tropical hardwoods: Branches with a diameter of about 0.5–2 cm have a respiration of about 70–100 mg CO2 per kg fresh weight per hour at 20°C. Trunk sections with a diameter over 20 cm have a respiratory activity of about 3–5 mg CO2, per kg fresh weight per hour at 20°C. In the older parts of a stem most of the cells are dead. The agreement in respiratory activity probably means that the “concentration” of living cells in the older parts of the stem of tropical and temperate hardwoods is the same.

    Notes: Respiratory Activity in Leaves from Herbs in the Tropical Rain Forest.—Plants of the undergrowth flora In the tropical lowland rain forest have typical shade-leaves distinguished by low dry matter percent, large leaf area per gram fresh weight and very low respiratory intensity per unit area of leaf blade. When the respiratory intensity measured at 26°C is converted to 20°C, the values lie somewhat lower than those for extreme shade-leaves of the temperate forests of Denmark. The leaf blades of Lomariopsis guineensis have on the whole the lowest respiratory intensity so far measured in leaf blades: 0.06 mg CO2 per 50 cm2 leaf blade (one side only) and hour at 20°C. The semisucculent shade-leaves of Palisota hirsuta constitute an exception with regard to area per gram fresh weight, in which respect they resemble the semi-succulent shade-leaves of the fern Ophioglossum vulgatum in Denmark.Die Bodenflora von höheren Pflanzen in einem tropischen Regenurwald im Tiefland besteht teils aus Kräutern, teils aus kleinen Bäumen, die eventuell zu grossen heranzuwachsen vermögen; dagegen sind absolut keine Straucher vorhanden. Die Blatter von einigen Kräutern im Urwald bei Adiopodoumé, Elfenbeinsküste, (5°, 20’ nördl. Br, 4°, 10’ west. L) wurden untersucht und zwar folgende: Aframomum sceptrum Schum. (Zingiberaceae), Palisota hirsuta Schum. (Commelinaceae) und Lomariopsis guineensis Kuhn (Farn aus der Familie Polypodiaceae).
