Glycine Max L

In the mountains of Northern Vietnam, frequent and intense acid rain affects the crops. This paper assesses the impacts of simulated acid rain (SAR) on the growth and the yield of soybeans (Glycine max (L.) Merr.) in Hoa Binh province. A field study in the summer–autumn seasons in 2017 (from May to August) in an area of 189 square meters was arranged according to a Randomized Complete Block Design (RCBD) with three repetitions including six treatments and a control. The experimental area was protected from ambient rain. Soybean plants were exposed three times a week to SAR at pH 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, and 6.0 (control). The results show that the growth parameters such as germination rate, stem length, and the number of main branches of the plants dramatically decreased in a dose–effect experiment. Gradual declines in the chlorophyll content (indirectly determined by SPAD) and the leaf area index (LAI) were observed as the acidity increased. The actual yield and yield components also tended to decrease when the pH of the rainwater fell, especially in the experimental plots treated at pH 3.0. The growth and yield of soybean were adversely affected when the plants were exposed to simulated acid rain, especially from a pH value of 3.5 and lower. This is the first study to evaluate the effects of acid rain on the growth and the yield of soybean grown in the mountains of Northern Vietnam.

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.

The response of seven soybean (Glycine max (L.) Merrill) cultivars to 0.56, 0.84 and 1.12 kg/ha pre-emergence applications of metribuzin [4-amino-6-tert-butyl-3-(methylthio)-as-triazin-5(4H)-one] was evaluated in Brookston clay loam soil. Slight foliar injury and stand reduction occurred at 0.56 kg/ha but damage became more severe as the rate was increased to 0.84 and 1.12 kg/ha. Plant height and bottom pod height were also reduced as the metribuzin rate was increased. Yield reductions occurred with the Steele and Harlon cultivars at the 1.12 kg/ha rate. Harosoy 63 was the cultivar most tolerant to metribuzin with Amsoy 71, Wells and Evans showing moderate damage and Steele, Harlon and XK-505 being the most sensitive.

The legume seed coat is the site of sucrose unloading and the metabolism of imported ureides and synthesis of amino acids for the developing embryo. The cell types directly responsible for these functions in the seed coat are not known. We recently described a convex layer of tissue on the inside surface of the soybean (Glycine max L. Merr.) seed coat that was termed “antipit” because it was in direct opposition to the concave pit on the abaxial surface of the cotyledon. Cone cells of the antipit contained numerous hypertrophied Golgi apparatus and laminated rough endoplasmic reticulum common to actively secreting cells. The initial report by Dzikowski (1936) described the morphology of the pit and antipit in G. max and found these structures in only 68 of the 169 seed accessions examined.
