“…Pigott & Taylor (1964) and Rorison (1968) found positive responses to P addition, in term of biomass, for seedlings of some forest herbs. More recent experimental work by Hipps et al (2005) showed similar patterns: in a glasshouse bioassay with four forest herbs growing on peat-based compost, they found species-specific effects of P addition on the P uptake and biomass of the forest herbs. Following the recommendations to perform plasticity studies in ecologically relevant, natural settings and multifactor environments (Sultan 2000;Miner et al 2005;Valladares et al 2007), this study aims to extend the previous experimental work by introducing some real-world complexities.…”

“…Within each block, we applied three different P levels (fully crossed with the two soil types): control, 50 mg P/pot and 210 mg P/pot. These levels were in the same order of magnitude as in the previous work by Pigott and Taylor (1964) and Hipps et al (2005). Adjusted solutions of NaH 2 PO 4 were used as P source.…”

“…We measured P uptake and biomass (cf. Rorison 1968;Hipps et al 2005), and also recorded a suite of plant traits related to growth and reproduction. Finally, the four forest herbs used in our study strongly differ in their capacity to colonize post-agricultural forest (Verheyen et al 2003 , Table 1), which enabled us to test whether fast colonizers actually respond stronger to P availability than slow colonizers.…”

Plasticity in response to phosphorus and light availability in four forest herbs

et al. 2010

The differential ability of forest herbs to colonize secondary forests on former agricultural land is generally attributed to different rates of dispersal. After propagule arrival, however, establishing individuals still have to cope with abiotic soil legacies from former agricultural land use. We focussed on the plastic responses of forest herbs to increased phosphorus availability, as phosphorus is commonly found to be persistently bioavailable in post-agricultural forest soils. In a pot experiment under field conditions, we applied three P levels to four forest herbs with contrasting colonization capacities: Anemone nemorosa, Primula elatior, Circaea lutetiana and Geum urbanum. To test interactions with light availability, half of the replicas were covered with shade cloths. After two growing seasons, we measured aboveground P uptake, vegetative and regenerative performance. We hypothesized that fast-colonizing species respond the most opportunistically to increased P availability and that a low light availability can mask the effects of P on performance. All species showed a significant increase in P uptake in the aboveground biomass. The P addition had a positive effect on the vegetative performance of two of the species, which was, however, unrelated to their colonization capacities. The regenerative performance was affected by light availability (not by P addition) and was related to the species' phenology. Forest herbs can obviously benefit from the increased P availabilities in post-agricultural forests, but not all species respond in the same way. Such differential patterns of plasticity may be important in community dynamics as they affect the interactions among species.

Summary1. Afforestation of agricultural land has become an important issue in Europe during the past two decades. In particular, broadleaf plantations have been promoted as multifunctional forests for biodiversity, timber production and recreation. The aim of this study was to analyse how the colonization of ground-layer plants in recently planted woodlands is affected by stand age, spatial isolation, former land-use type and canopy species. 2. Colonization was studied in 50 plantations of pedunculate oak Quercus robur and 16 plantations of European sycamore Acer pseudoplatanus on former arable land and open pastures in the Torup-Skabersjö area of southern Sweden. Twelve oak plantations and 10 sycamore plantations on ancient woodland sites were used as reference areas. 3. Woodland species richness increased continuously with stand age in plantations contiguous with ancient woodland. The oldest plantations (70 -80 years) approached the species richness of ancient oak woodland. Species richness decreased with increasing distance from ancient woodlands, and there was no significant increase in species richness between stands aged 20 and 80 years in isolated plantations. Most species that regularly colonized isolated plantations had adhesive seeds or small, wind-dispersed diaspores. 4. Ordination analysis showed clear differentiation between former land-use categories and spatiotemporal stand categories (recently isolated, recently contiguous and ancient). No consistent differences were found in vegetation patterns in oak and sycamore stands. Woodland species richness was similar on former arable land and open pastures. Pasture plantations were characterized by the presence of more acid-tolerant species, whereas the frequency of some acid-sensitive species was higher on former fields. 5. Synthesis and applications. This study demonstrates that new woodland should build out from cores of ancient woodland for optimal ground vegetation development. A species-rich ground vegetation can be achieved by spontaneous colonization within 70-80 years when plantations are contiguous with ancient woods. Formerly cultivated soils are generally well suited for understorey plants of forests on base-rich loamy soils as long as closed canopy conditions are maintained. However, many typical forest species are not able to disperse across open fields and their establishment in isolated stands will require sowing or planting.

“…The effects of poor nutrition, be it through infertile soils or incorrect soil pH level, directly affect the production of chlorophyll molecules resulting in chlorosis of leaves and a reduced photosynthetic rate, thus inhibiting some biological processes and decreasing the general health of the plants [23][24][25]. There are plausible mechanisms through which the production of chlorophyll could be affected, for example, the pH level of a growing medium affects the uptake of P [26] and the P level influences the nutrient uptake by plants [27]. The relationship between the nutrient P and chlorophyll is not fully understood.…”

Salvia chamelaeagnea (Lamiaceae) is a slow growing water-wise evergreen shrub originating from the western province of South Africa. It is an attractive landscape, and S. chamelaeagnea is a medicinal plant. It is important to develop enhanced cultivation protocols that could result in high yield and high-quality medicinal materials. Chlorophyll is a fundamental part of the light-dependent reactions of the photosynthesis process. This chapter investigates the effects of four phosphorus concentrations and three pH levels of supplied irrigated water on the production of chlorophyll A, chlorophyll B, total chlorophyll, leaf colour and the nutrient uptake of S. chamelaeagnea grown in hydroponics over an 8-week period at the Cape Peninsula University of Technology. The treatments of pH 4, pH 6 and pH 8 at 31, 90, 150 and 210 ppm of phosphorus were received by 12 groups of plants and were replicated 10 times. The results indicated that at pH 4, P fertilization significantly (P < 0.05) induced a higher chlorophyll production of S. chamelaeagnea grown in hydroponics compared to other pH treatments (pH 8 and pH 6).
