Differential response of soybean genotypes to two lime rates

Genetics of resistance to two strains of soybean mosaic virus in differential soybean genotypes.

There are seven pathotypes of soybean mosaic virus (SMV) representing seven strain groups (G1-G7) in the United States. Soybean genotypes [Glycine max (L.) Merr.] may exhibit resistant (R), susceptible (S), or necrotic (N) reactions upon interacting with different SMV strains. This research was conducted to investigate whether reactions to two SMV strains are controlled by the same gene or by s...

Response of two soybean cultivars to moisture stress

Differential Response of Two Soybean Cultivars to Paraquat

The soybean cultivars “ K w angkyo” and “H o o d ” are differentially sensitive to the bipyridylium herbicide paraquat (l,r-d im ethy l-4 ,4 '-b ipyrid in ium ion). This was confirm ed by visible injury observations, m easurem ents o f desiccation levels and chlorophyll conten t, and tracings o f chlorophyll fluorescence induction o f fully expanded first trifoliate leaves o f these two culti­ ...

Transcript Profile of the Response of Two Soybean Genotypes to Potassium Deficiency

The macronutrient potassium (K) is essential to plant growth and development. Crop yield potential is often affected by lack of soluble K. The molecular regulation mechanism of physiological and biochemical responses to K starvation in soybean roots and shoots is not fully understood. In the present study, two soybean varieties were subjected to low-K stress conditions: a low-K-tolerant variety...

Evaluation of Tolerance of Some Soybean Genotypes to Drought Stress

     In order to recognize the soybean tolerant genotypes, a greenhouse as factorial experiment was conducted in form of randomized complete block design with three repetition in 2017 in Damavand. The first factor contained 15 soybean genotypes and second factor included two levels of normal irrigation and irrigation disruption in time of podding. The traits included plant height, reproductive ...
