“…5). A similar stability of the chlorophyll alb ratio was also found in Pteris cretica L. (Hariri and Brangeon 1977) and in Betula penduta Roth. (Oquist et al 1982); but contrary to P. major ssp major a stable rate of photosynthesis occurred in these plants.…”

“…A higher chlorophyll content is a common response to shading (Boardman 1977, Wild 1979. Over a large light energy range (4-250 W m"^) the chlorophyll content of Pteris cretka L. decreased with increasing irradiance (Hariri and Brangeon 1977). Blias and Masarovicova (1980) compared species of sonny and shaded habitats: the species of shaded habitats had a higher chlorophyll content.…”

Growth, root respiration, photosynthesis, dark respiration, chlorophyll content and chlorophyll alb ratio were followed in two genotypes of Plantago major L. ssp major L., originating from an exposed and a shaded habitat, respectively, at two levels of irradiance. In addition, responses of these processes to a transfer of plants from one light condition to the other were studied. Genetic differentiation between the two genotypes was reflected in growth rate, photosynthetic activity, dark respiration and chlorophyll content. Individuals of the genotype originating from a shaded habitat were less inhibited by low irradiance: growth was less depressed at low irradiance, while the genotype of the exposed habitat seemed to be more restricted to exposed conditions. The adaptive plastic response of growth and physiological parameters upon an alteration in irradiance was very small. The shoot to root ratio was a stable plant characteristic in these experiments. Plants of both genotypes were probably damaged after a transfer from the low to the high level of irradiance; the growth of these plants was not stimulated by high irradiance, and the photosynthetic activity was even decreased. Plants, which were transferred to the low level of irradiance, showed an immediate effect of the change and no adaptive response was observed. Obviously, the ability to perform adaptive plastic responses, which was demonstrated in the non‐transferred plants after pretreatment, had been lost during the experiment and was confined to the seedling stage of individuals of the two genotypes.

“…The growth conditions for Pteris cretica plants are described in the first paper (Hariri and Brangeon 1977). Five conditions were realized; two in controlled growth chambers (irradiance; 16 and 62 W m~'^) and three in the greenhouse (fluctuating light: 4-8 W m-^ 20-32 W m^^ = control and 20-250 W m"'^).…”

The photosynthetic capabilities of the fern Pteris cretica var. ouvrardii were analysed by means of the light response curves of CO2 exchange. In control growth conditions (greenhouse, low‐light: 20–32 W m−2); photosynthesis was shown to be saturated for low irradiance (20–25 W m−2); the saturating photosynthetic rate, very low as compared to higher plants, was due to an extremely high intracellular resistance. When irradiance during the photosynthesis measurement was higher than 60–80 W m−2, a constant decline of net CO2 exchange as a function of time was observed. When irradiance during growth was enhanced, whether in greenhouse (20–250 W m−2) or controlled (62 W m−2) conditions, the first fronds that had developed in the new condition from the crosier stage exhibited decreased net maximal photosynthesis and a decreased efficiency in low light, but saturating irradiance was unmodified. However, the fronds whose entire differentiation (from meristem) occurred under these moderate irradiances (plants defoliated of all fronds and crosiers at the time of transfer), possessed more efficient photosynthetic characteristics than control plants. Pteris is able to grow under extreme shade conditions (4–8 W m−2); light saturating photosynthesis and efficiency are higher under extreme shade than under control conditions. These adaptive characteristics indicate that Pteris is a well‐adapted shade species.

“…The Pn of leaves from fruiting and non-bearing trees are similar to that reported by Hansen (1970), Chalmers et al (1975), Fujii and Kennedy (1985), De Jong (1986), and Wood (1988. However, other researchers using other plant species have questioned the effects of carbohydrate accumulation in leaves on the photosynthetic rate (Ballantine and Forde, 1970;Wilkinson and Beard, 1975;Geiger, 1976;Hariri and Brangeon, 1977;Carmi and Shomer, 1979;Melis and Harrey, 1981;Lichtenthaler et al, 1982). Daie (1985) In the present study, the total growth of the new roots at the stage of fruit harvest was larger in defruited trees.…”

SummaryEffects of fruiting on leaf characteristics, photosynthesis, and root growth were assessed on small peach trees (Prunus persica (L.) Batsch. cv. Hakuto) after adjusting the number of fruits per tree.1. Compared to leaves on non-bearing trees, those on fruiting trees were thinner, less wide, and darker green. The more intense green pigmentation indicates that the chlorophyll was more concentrated in leaves of bearing than in those from non-bearing trees. During the fruit maturation stage, former accumulated more starch in the chloroplasts than leaves of the latter as determined by the I-KI staining method, transmission electron microscopy, and starch analysis. The photosynthetic rate per unit leaf area (Pn) was faster in leaves of fruiting limbs during the fruit maturation stage; no significant difference in Pn between leaves of fruiting and defruited branches was detected during Stage II of fruit development.2. The elongation of new roots in fruiting trees was reduced proportionately to increasing fruit number during the fruit growth period, whereas the new roots on non-bearing trees continued to elongate throughout the vegetative period. At fruit harvest, the total root volume of non-bearing trees was larger and the starch content per root dry weight was higher. On fruiting trees, renewed root growth was observed several days after harvest while the starch in the roots continued to accumulate until the leaves senesced.
