TL;DR: A great number of lichens from Central Europe, the Mediterranean, New Zealand, and the Negev Desert, Israel tolerated cold treatments which can never be expected in these areas.
TL;DR: The Valle del Lucomagno became free of ice in the Bolling period at the latest, whilst the slope terraces of Brigels and Obersaxen (Vorderrhein Valley) did so in the Allerod period, and the existence of a pre-boreal cold phase (Piottino fluctuation) in four different places was confirmed.
TL;DR: According to phenological observation and experimental data, dormancy lasts throughout the hot summer season and may be thus considered an important developmental adaptation to fit the local climatic pattern.
TL;DR: The ramification system and the histological structures of Trevoa trinervis, a shrub from the Chilean matorral, are studied and several of the characters described are interpreted as adaptations to drought.
TL;DR: Scholander's pressure chamber technique was used for determining suction tension in the crown of a giant sequoia, Sequoiadendron giganteum (Lindl.) Buchholz as discussed by the authors.
TL;DR: The present paper demonstrates the growth rhythms of a number of representative species and finds that the intensity of root degrowth creases and growth stops in October-November under the climatic conditions of Eberswalde.
TL;DR: Cuticular waxes isolated from several Pinus silvestris provenances which differ in the resistance to Lophodermium pinastri were analysed by thinlayer- and gaschromatography and found the resistant proveniences “Bergen” and “Grebenau” have a higher C 29 -alcohol and C 31 -paraffin content than the more susceptible provenances.
TL;DR: In this paper, a study of anaerobic metabolism in animals and plants able to survive in oxygen-poor environments shows that metabolic solutions to a given environmental stress, whether in plants or animals, can be strikingly similar.
TL;DR: The author analysed form and size of the epidermis cells and the density of stomata on the upper and lower side of the basal, middle, and superior leaves of Carlina.
TL;DR: Vernalization seems to be most important adaptation, preventing the autumn flowering in the investigated therophytes, and is in a good agreement with phenological observations of flowering time of the plants in their natural habitats.
TL;DR: Investigations have been carried out on the ecophysiological adaptations for survival of the two important desert trees: Salvadora persica Linn, and S. oleoides Decne.
TL;DR: In the lower altitudinal zone (eukolline stufe) of the hill region of Saxony the assimilation apparatus in spruce works with a lower number of annual sets of needles and with lighter needles than in the higher altitude zone (hochkolline Stufe). Compared with needles from the high altitude zone, the climate of which is moister and cooler, needles grown under the drier and warmer conditions of the lower altitude zone possess a higher nutrient content with manganese, calcium, and nitrogen as mentioned in this paper.
TL;DR: The gynOecium of Nigella damascena cannot be called as being pseudocoenocarpal in the sense of Troll, but an eusyncarpal gynoecium exists, that is divided into a synascidate, a synplicate, a hemisynplicate and a asynplicates section.
TL;DR: In this article, the authors investigated the aspects of quantity of total nitrogen mineralized and predominance of N H 4 + or NO 3 − nitrogen in 35 forest-sites of Southern Badenia.
TL;DR: The present investigation visualizes the significance of Chloris gayana as a salt tolerant range species that could be grown in areas where saline irrigation is applied because of its relatively high osmtoic pressure and its ability to accumulate more salts in the cell sap.
TL;DR: In this paper, it is demonstrated that by a common statistical procedure, determination of the correlation between water deficit and reachable re-saturation, it is possible to establish a specific value of each species, this value being easily reproducible.
TL;DR: In teratologically isolated carpels of Salix replacing stamens, the margins are congenitally fused up to the apex with some ovules being borne only basally, and this affords a clue to the interpretation of normal carpels in Typha, the Potamogetonaceae, the Bignoniaceae and the Caryophyllaceae.
TL;DR: The contents of storage carbohydrates in barks of Cercis show distinct seasonal variations which similar to those of Quercus baloot and of Central European species.
TL;DR: The following facts argue against the view stated by G rummer (1958), that toxic substances derived from the leaves of Camelina were the main causes for the decrease of flax-growth.
TL;DR: The comparison of SO 2 and fluorine resistance groups shows that with regard to the time of occurrence of first injuries and extent of damage the great majority of plants respond in a similar way to both pollutants.
TL;DR: In this article, the stages of development of a spring fen in the central Thuringian mountains and of the surrounding mosaic of vegetation have been reconstructed using a combination of palynological and phytosociological methods.
TL;DR: A water supply equivalent to 200 mm was found to be the least level required for production of grains and the effect of drought on yield and water relations of plants was studied on plants subjected to different periods of drought.
TL;DR: Investigation of fixed pollen tubes of Tradescantia paludosa found that the immigration of the nuclei takes place after the pollen tubes have grown to a definite length, stressing once more the importance of cyto-morphological studies as a precondition for a critical cy to-biochemical analysis of the development of the male gametophyte in higher plants.
TL;DR: Four peat-profiles of the plateau of the ‘Waldviertel’ in Lower Austria have been investigated by pollen-analysis and it can be shown, that this principle of dating can only be employed to a very limited extent.
TL;DR: The measurements were performed in a pole wood on a sandy soil with deep groundwater and there was a high coefficient of determination for the non-linear regression of time parameter and temperature upon current increment.
TL;DR: In this article, the authors present the results on sequential sowing experiments carried out as a part of the international Theme 1 (Initial experiments) within Photosynthesis program of IBP/PP.
