“…Phosphorus addition strongly promoted growth of the four B. alnoides clones, indicating that phosphorus deficiency was a major limiting factor for plant development in the nursery environment (Warren & Adams 2002) similar to studies on aspen and its hybrids (Liang & Chang 2004), and three Leucadendron cultivars (Silber et al 2000). However, the root to shoot ratio of B. alnoides plants showed little response to phosphorus addition in the present study.…”

., 2016. Growth and nutrient efficiency of Betula alnoides clones in response to phosphorus supply. Ann. For. Res. 59(2): 199-207. Abstract.As phosphorus deficiency limits the productivity of many plantation forests in Asia, there is considerable interest in developing phosphorus-efficient clones for the region through targeted breeding programs. Therefore, we determined growth, nutrient concentrations and nutrient absorption and utility efficiencies of four Betula alnoides clones (C5, C6, 1-202 and BY1) in response to six phosphorus levels of 0, 17, 52, 70, 140 and 209 mg P plant -1 coded as P1 to P6, respectively. Maximum growth occurred in the P4, P5 and P6 plants since they had the largest height, biomass, leaf area and branch number. Phosphorus application increased the phosphorus concentrations of all clones. Nutrient loading was achieved with the P6 treatment because growth and biomass were not significantly higher, but root, stem and leaf phosphorus concentrations were approximately twice those of P4 plants. Clone BY1 had the highest phosphorus-efficiency, and is recommended for field application due to its maximum root collar diameter, biomass, root/shoot ratio, leaf area, nutrient absorption and utility efficiency among the four clones. The findings will help to improve the nutrient efficiency of this species in plantation forestry in Asia.

“…Meanwhile, the high level of Ca and Mg salts (Ca 640 and Mg 384 mg/l) had negative effects on celery above-ground fresh weight, dry shoot biomass and leaf area, which was probably due to osmotic stress. The reduction in yield as a result of P deficiencies was reported previously in many plants (Silber et al 2000;Gikaara et al 2004;Johnston et al 2006). The main effect of P deficiency is the reduction in celery growth rate leading to darker green and smaller leaves, shorter stature, fewer leaves and imbalance between shoot and root growth (Dufault 1985).…”

Li Y., Wang T., Li J., Ao Y., 2010. Effect of phosphorus on celery growth and nutrient uptake under different calcium and magnesium levels in substrate culture. Hort. Sci. (Prague), 37: 99-108.A greenhouse pot experiment was performed to study the effect of phosphorus (P) on celery (Apium graveolens L.) growth, quality and nutrient uptake under different calcium (Ca) and magnesium (Mg) levels in substrate culture. Results showed that there were significant interactions between P and the level of Ca and Mg in the growing media. Celery above-ground fresh weight, total dry biomass, leaf area, and P, Ca and Mg concentrations in celery leaves significantly increased from 0 to 124 mg/l P application. The opposite trends were observed for root/shoot ratio, leaf chlorophyll, carotenoids, soluble protein, soluble sugar, vitamin C, and nitrogen and potassium concentration in celery leaves. Medium Ca and Mg level (Ca 320 and Mg 192 mg/l) significantly increased celery above-ground fresh weight, total dry biomass and leaf area compared to low (Ca 160 and Mg 96 mg/l) and high (Ca 640 and Mg 384 mg/l) levels. This study suggested that 124-248 mg/l P applications under medium Ca and Mg level were appropriate for celery nutritional requirements.

“…Thus, the dry weight (shoots and roots) production of L. 'Safari Sunset' fed with an adequate P level (20 mg L -1 ) was quite similar to that of L. coniferum plants under the same conditions. The dry weight production (shoots plus roots) of L. muirii plants and their response to the fertilization treatments were the lowest (Silber et al 2000b).…”

“…The response of two other Leucadendron cultivars (clonal selections of L. coniferum and L. muirii) to different P level was also tested by Silber et al (2000b). The development of L. coniferum (L. 'Orot') plants under P deficiency (no P added in the irrigation water) was significantly superior to that of L. 'Safari Sunset' and L. muirii cultivars, but as P application increased to 20 mg L -1 , the growth of L. 'Safari Sunset' became quite similar to that of L. coniferum.…”

More than 1400 species have been recognized in the ancient Proteaceae family (Rebelo 1995). Their occurrence is mostly distributed between Australia with about 800 species and Africa with about 400 species with the remainder found in South America, the islands east of New Guinea, and a few species in southeast Asia, New Zealand, and Madagascar. They are broadly referred to as proteas, although we identify specific genera by their Latin names. The subfamily Proteoideae, largely found in Africa, has contributed the genera Protea, Leucadendron, and Leucospermum to floricultural trade, while the Australian Grevilleoideae has contributed Banksia and Grevillea that have found similar use in floriculture and landscaping. Other genera are still emerging in importance (Criley, 2001
