The nodulation of Glycine max cv. Lambert and the nodulation-restricting plant introduction (PI) genotype PI 417566 by wild-type Bradyrhizobium japonicum USDA110 is regulated in a population-density-dependent manner. Nodulation on both plant genotypes was suppressed (inhibited) when plants received a high-density inoculum (10(9) cells/ml) of strain USDA110 grown in complex medium, and more nodu...

Different biological parameters of the stink bugs, Nezara viridula L. and Piezodorus guildinii Westwood (Hemiptera: Pentatomidae), are affected by the developmental stage of the soybean (Glycine max Merrill) pods they feed on. These effects of the soybean on the stink bugs could represent a selection pressure leading to the ability of these species to discriminate the phenological stage of soyb...

Naturforsch. 49c, 719-726 (1994); received August 1/September 7, 1994 Glycine max, Triticum aestivum, 3,4-Dichloroaniline, Metabolism, Translocation The roots of 13-day-old soybean (Glycine max L.) and 7-day-old wheat ( Triticu...

   Phenolic extracts of canola (Brassica napuse L.) contains substances that inhibited the germination and seedling growth of soybean (Glycin max L.). These compounds also affect activity of some enzymes. Hear, we investigated the allelopathic effects of various canola plant parts on soybean germination, seedling growth, and biochemical aspects. Phenolic extract of canola shoot (including leaf,...

AAC Richard is a food grade soybean [Glycine max (L.) Merr] cultivar with yellow hilum, high protein concentration, and good processing quality for foreign domestic soymilk, tofu, miso markets. It has resistance to SCN (soybean cyst nematode) (Heterodera Glycines Ichinohe). was developed at the Agriculture Agri-Food Canada (AAFC) Harrow Research Development Centre (Harrow-RDC), Harrow, Ontario ...

low phosphorous (p) availability in soils limits production of soybean [glycine max (l.) merr.] around the world. this study was conducted to determine whether exogenous expression of the rice (oryza sativa l.) phosphates transporter gene ospt2 would increase inorganic phosphates (pi) acquisition and improve yield in transgenic soybean. cotyledonary-node explants of the soybean were inoculated ...

The interactive effects of nickel (Ni) and ascorbic acid (AsA) and gibberellin (GA3) on soybean seedlings (Glycine max L. cv. Union × Elf) were examined. Seven-day old hydroponically-grown seedlings were exposed to NiCl2, 6H2O (0.5 mM), either with or without AsA (1 mM) or GA3 (0.05 mM) or AsA (1 mM) plus GA3 (0.05 mM), for five days. Nickel toxicity symptoms, such as formation of reddish-brown...

Soybean (Glycine max (L) Merr.) seed treatments are recognized as useful in reducing losses from seed borne pathogens and seedling damping off agents. The seed treatment with fungicide is essential in the improved technology for increasing crop production. In the present investigation two seed protectant fungicides captan and carbendazim are used. Effect of fungicides on growth of Rhizobium jap...

The apical 1-cm hypocotyl of dark-grown ;Clark' soybean (Glycine max [L.] Merr.) seedlings produced ethylene at rates of 7 to 11 nanoliters per hour per gram when attached to the cotyledons. Such physiologically active rates occurred prior to the deceleration of hypocotyl elongation caused by the temperature of 25 C.Daily exposure of the etiolated seedlings to red light promoted hypocotyl elong...

Ureide analyses of soybean (Glycine max L.) tissues were accomplished with a modified and simplified automated analysis used to determine allantoin concentration in rat urine. The length of the circuit and flow rates of the solutions were reduced, and NaOH was used for color development at room temperature. Keto-acids did not significantly interfere with the determinations of ureides except for...
