Elevated ozone and rising temperature are both factors in climate change, but they are difficult to study in combination due to exposure system requirements. We developed and deployed an air exclusion exposure system to treat soybean (Glycine max (L.) Merr.) cultivar “Jake” with season-long combinations of sub-ambient ozone (18 ppb, 12 h mean), elevated ozone (66 ppb, 12 h mean), and elevated temperature (+3.5 °C daytime, +2.4 °C nighttime) in irrigated field plots. Warming caused a shift in biomass partitioning from reproductive tissues into stems and petioles at mid-season that resulted in a significant 25% reduction in final seed yield and a significant reduction in harvest index. The elevated ozone treatment delayed mid-season biomass production, and final seed yield was reduced by a non-significant 2%. However, there were significant underlying effects of elevated ozone on seed production. The non-significant impact of ozone on seed yield of cultivar “Jake” resulted from significant increases in pod number (+16%) and seed number (+18%) that were offset by a significant reduction in seed size (−16%). No evidence of significant warming–ozone interactions was found in biomass or seed yield responses. In general, significant impacts of the individual warming or ozone treatments were found to be additive.

Glycine Max L

The interaction between proton and aluminium toxicities was examined in soybean (Glycine max L.), pea (Pisum sativum L.) and bean (Phaseolus vulgaris L.). Accurate characterization of genotype Al-sensitivity in solution culture experiments, employing a continuous Al-exposure, required response definition at both growth-enhancing and growth inhibiting activities. Essentially, this involved multiple controls to account for the interactive effects. Experiments measuring growth during a recovery period in Al-free solution were more successful in distinguishing genotypic response to Al, especially in species demonstrating high H+ -sensitivity. The time, concentration and basal solution dependencies of the characteristic genotype response for the three species examined were consistent with the hypothesis that responses of genotypes may be predicated upon conditions emphasizing irreversible (cell division) effects. Cell extension effects, however, appear to be rapid, largely-reversible and often not different between differentially Al-sensitive genotypes growing in a complete nutrient solution.

This study aims to determine the effect of various levels of salinity on several M5 soybean mutant lines. This research was conducted at the Laboratory of Seed Science and Technology and the Screen House of the Agrotechnology Study Program, Faculty of Agriculture, Syiah Kuala University. The experiment design that used was factorial 5x4 with three replications and continued the analisis data with the Honest Real Difference Test (BNJ) at 5% level. The first factor was the soybean genotype with 5 levels, namely the Kipas Putih B4, B7 and B15 mutants, and Kipas Putih (mutant parent) and Wilis varieties were used as a comparison. The second factor is the concentration of NaCl which consists of 0 g L-1 (0 ds / m), 4 g L-1 (4 ds / m), 6 g L-1 (5 ds / m), and 8 g L-1. (5.5 ds / m). The results showed that each genotype had different resistance to salinity. At a concentration of NaCl 4 gL-1 (4 ds / m), the genotype has begun to show a decrease in the value of viability and vigor of seeds as well as plant vegetative growth. There is no soybean genotype that is tolerant to salinity with the ability to germinate and grow above 80% or more. The genotypes of Wilis, Kipas Putih and mutants B4 had relatively better germination and growth power in salinity stress compared to mutants B7 and B15.

Treatment Interaction

Soybean (Glycine max (L.) Merr.) cult Hood and Dare were exposed to low concentrations of ozone or sulfur dioxide, or both, during the first 3 wk of growth. Foliar injury occurred on both cultivars in the ozone and mix treatments. Dare developed more foliar injury than Hood. Plant height, top and root fresh and dry weights, and the dry shoot–root ratios were significantly reduced by the 10-pphm ozone treatment. The mix of 5 pphm ozone plus 5 pphm sulfur dioxide significantly reduced top fresh weight, root fresh and dry weights, and shoot–root ratios. Treatments of 5 pphm ozone, 5 pphm or 20 pphm sulfur dioxide had no significant effects on plant growth. The growth reductions resulting from the ozone–sulfur dioxide mix were greater than the additive reductions of the single gases. The lack of a significant cultivar × treatment interaction indicated that the growth of the two cultivars responded similarly to the various treatments.
