Phosphorus concentration in barley (Hordeum vulgare L.) seed: Influence on seedling growth and dry matter production

Effect of seed phosphorus and soil phosphorus applications on early growth of rice (Oryza sativaL.) cv. IR66

“…The beneficial effects of the increase of seed P concentration on the growth of rice in the present experiment were consistent with reports from crops other than rice: barley (Zhang et al 1990), lupins and wheat (Bolland et al 1989;De Marco 1990), subterranean clover (Thomson and Bolger 1993).…”

Rhizosphere pH and phosphorus forms in an Oxisol cultivated with soybean, brachiaria grass, millet and sorghum

“…As previously mentioned, the main source of P for the soybeans during the evaluated period must have been the seed itself, thus reflecting low need of uptake of this nutrient and absence of P depletion of the soil. This positive relationship between the quantity of P in the seed and the dry matter production of the plants has already been reported for soybeans (Trigo et al, 1997), wheat (Zhu and Smith, 2001), clover (Thomson and Bolger, 1993), oats (Zhang et al, 1990) and rice (Ros et al, 1997), confirming the hypothesis that during the beginning of their development, certain species of plants may survive only with the P derived from the seed (Grant et al, 2001).…”

Mycorrhizal Symbiosis and Plant Reproduction

“…In Abutilon theophrasti, an increase in seed N content improved competitive ability of the offspring (Parrish and Bazzaz 1985). An increase in seed P content can also positively affect the germination, growth or reproductive output of the offspring such as in Campanula (Nuortila et al 2004), Pisum (Austin 1966), in other legumes (Bolland and Paynter 1990), and in Hordeum (Zhang et al 1990). Thus, even when additional P supplied by the mycorrhizal fungus does not result in increased seed number (when seed production is no longer P-limited), significant consequences to the next generation of plants may still result from mycorrhizal infection of the former generation.…”
