Glycine Max L

Soybean (Glycine max L.) is a significant legume of food and plays a vital role in human livelihood. It is rich in proteins (40%), which contain major essential amino acids, and edible oil (20%). Salinity stress affects soybean yield 30-80%. Salinity stress significantly reduces net photosynthetic rates, increases energy losses for the mechanism of salt exclusion, substantially decreases nutrient intake and ultimately results in reduced plant growth. Present investigation was conducted to show how morphological and biochemical changes occur due to the stress of salinity on the soybean plant genotypes. Stress with salinity resulted in increased protein and proline content to withstand stress with salinity. Better root length, shoot length fresh weight and dry weight were observed of JS-355 variety. The JS-355 variety demonstrated the better response to all concentrations of salt stress used from 40 mM to 280 mM. As the salt concentration increases, so does the protein and proline concentration. The JS-355 variety showed the better results at all salt concentrations. The highest protein and proline content at high salt concentration was observed in varietyJS-355.

Response of various soybean varieties [Glycine max (L.) Merril] againts peanut stripe potyvirus infection. This experiment was conducted to investigate the effect of PStV infection on soybean growth of various soybean varieties. Treatments were arranged in completely randomized design in split plot experiment with four replications. Main plots were virus-inoculated and uninoculated plants; subplots were eight soybean varieties (Wilis, Orba, MLG2521, Amerikana, Yellowbean, B3570, Slamet and Taichung). The results showed that infection decreased soybean growth indicated by reduction dry weight of soybean plant and reduction of soybean yield. Slamet variety compared to other varieties showed susceptible reaction indicated by the shortest incubation period (9,75 days), significant reduction of dry weigh of soybean plant, and the highest reduction of soybean yield (23,6%). Thaicung variety showed resistant reaction indicated by longest incubation period (14,3 days) and insignificant reduction of soybean growth and yield.

The aim of this research want to know the influence of the addition Rhizobium bacteria species, dose and combination both of them, on growth and production of soybean plant (Glycine max (L) Merr.). The experimental design of this research was factorial design 4×2, 4 species of Rhizobium are R1 = Rhizobium japonicum, R2 = R. phaseoli, R3 = R. leguminosarum, R4 = mixture of R1, R2 and R3, and 2 dose of inoculan Rhizobium (D1 = 5 m/plant, and D2 = 10 ml/plant) with 1010 sel bacteria/ml and 5 replications. Independent variable is species of Rhizobium, dose of inoculan Rhizobium and combination both of them. Dependent variable is dry matter, weight of nodules and dry weight of seeds. The harvest data was analyzed by Kruskal-Wallis Test using 5% level (a = 0.05) followed by Mann- Whitney Test. The result of this research show that species of Rhizobium, dose of inoculan Rhizobium and combination both of them present insignificant result (a > 0.05) on soybean growth and production, but the mixture of Rhizobium species with high level dose of bacteria, present better result than single species with low dose of bacteria.

The study was aimed at assessing the response of soybean plant (Glycine max L.) to inoculation of arbuscular mycorrhizae and application of phosphorus fertilizer on acidic soil. The study was conducted from February to June 2013. A factorial completely randomized design was used. The first factor was inoculation  of mycorrizhae consisting of two levels, namely no inoculation and mycorrizhae inoculation of 10 g/plant. The second factor was the application of phosphorus fertilizer in four levels, namely 0 kg SP-36/ha, 100 kg SP-36/ha, 200 kg SP-36/ha, and 300 kg SP-36/ha. Results showed that soybean plant given no mycorrhizae of 10 g/plant had higher plant height at 3 weeks after planting (WAP) than those given no mycorrhizae. The application of phosphorus fertilizer was found to give significant effects on plant height at 4-7 WAP, number of leaves at 6 WAP, trunk diameter, root  length, number of productive branches, fresh and dry weight of roots, fresh and dry weight of root nodes, age at first flowering, number of root nodes, leaf width, pod dry weight, number of one seeded pods and three seeded pods. It was also found that the interaction between inoculation of arbuscular mycorrhizae and application of phosphorus fertilizer gave significant effects on number of leaves at 7 WAP, canopy dry and fresh weight, pod fresh weight, number of two seeded pods, total plant fresh and dry weight, total dry seed weight, number of total pods, and number of seeded pods.Key words: Glycine max L., root nodes, pod dry weight, seeded pods

Salinity Levels

Understanding salt tolerance in tomato (Solanum lycopersicum L.) landraces will facilitate their use in genetic improvement. The study assessed the morpho-physiological variability of Hail tomato landraces in response to different salinity levels at seedling stages and recommended a tomato salt-tolerant landrace for future breeding programs. Three tomato landraces, Hail 548, Hail 747, and Hail 1072 were tested under three salinity levels: 75, 150, and 300 mM NaCl. Salinity stress reduced shoots’ fresh and dry weight by 71% and 72%, and roots were 86.5% and 78.6%, respectively. There was 22% reduced chlorophyll content, carotene content by 18.6%, and anthocyanin by 41.1%. Proline content increased for stressed treatments. The 300 mM NaCl treatment recorded the most proline content increases (67.37 mg/g fresh weight), with a percent increase in proline reaching 61.67% in Hail 747. Superoxide dismutase (SOD) activity decreased by 65% in Hail 548, while it relatively increased in Hail 747 and Hail 1072 treated with 300 mM NaCl. Catalase (CAT) activity was enhanced by salt stress in Hail 548 and recorded 7.6%, increasing at 75 and 5.1% at 300 mM NaCl. It revealed a reduction in malondialdehyde (MDA) at the 300 mM NaCl concentration in both Hail 548 and Hail 1072 landraces. Increasing salt concentrations showed a reduction in transpiration rate of 70.55%, 7.13% in stomatal conductance, and 72.34% in photosynthetic rate. K+/Na+ ratios decreased from 56% for 75 mM NaCl to 85% for 300 mM NaCl treatments in all genotypes. The response to salt stress in landraces involved some modifications in morphology, physiology, and metabolism. The landrace Hail 548 may have better protection against salt stress and observed protection against reactive oxygen species (ROS) by increasing enzymatic “antioxidants” activity under salt stress.

This research deals with the effects of exogenous growth regulators on production of soybean plant (Glycine max cv.. Davis) under greenhouse conditions, At the flower anthesis, 2,3,5-triiodobenzoic acid (TIBA) 20 ppm was applied. Other two applications with TiBA, with intervals of four days, were realized. Before flowering, Agrostemin (1 g/10 ml/3 1), gibberellic acid (GA) 100 ppm, and (2-chloroethyl) trimethylammonium chloride (CCC) 2,000 ppm were applied. It was observed that CCC and TIBA reduced stem dry weight. Soybean plants treated with TIBA reduced weight of pods without seeds , seed number and seed weight.

Root traits are essential for optimising nutrient and water absorption and anchorage. However, changes in root traits and the contribution of root-to-shoot growth and development of soybean (Glycine max (L.) Merr.) across a century of breeding are poorly documented. In this study, we adopted a grafting technique, using 55 cultivars released in the three main soybean-production regions in China as rootstocks in a pot experiment and 24 cultivars from the Yellow-Huai-Hai Valley (YHH) region as rootstocks in a field experiment, with cv. Zigongdongdou as the common scion. Changes in soybean roots, including dry weight (DW) of roots, lateral root number (LRN) and taproot length (TRL), and their contribution to shoot development and biomass formation, including shoot DW, plant height and node number, were evaluated under optimal conditions in 2011. Aboveground traits declined with year of release in the YHH region and did not vary over time in the northern Heilongjiang province and mid-south Heilongjiang region except for shoot DW. The root traits root DW, LRN and TRL were similar over years of release in the pot and field experiments. The results suggest that the newer cultivars have lesser shoot growth and root capacity but the same amount of root growth as older cultivars. Root traits did not change during selection, suggesting that improvement in soybean root traits should be an aim in future breeding.
