We evaluated genetic variations in the non-structural carbohydrate (NSC) and the cell-wall components of stem in rice, sorghum, and sugar cane to assess the potential suitability of these gramineous crops for bioethanol production. For NSC, the maximum soluble sugar concentration was highest in sugar cane, followed by sorghum with sucrose. The major NSC in rice was starch, but there were wide v...

To reduce Cd phytoavailability in calcareous soils, the effects of soil amendments of red mud, rape straw, and corn straw in combination with zinc fertilization on Cd extractability and phytoavailability to spinach, tomato, Chinese cabbage and radish were investigated in a calcareous soil with added Cd at 1.5 mg kg-1. The results showed that water soluble and exchangeable Cd in soils was signif...

Abstract Key message Short-term nitrogen (N) deposition stimulates phosphorus (P) demand owing to the growth improvment of Phyllostachys edulis seedlings. Increased N loads led acquisition and utilization sufficient P, while limitation P starvation could be alleviated by higher activity soil acid phosphatase use efficiency rather than resorption from senescent organs. Context Plants in most ter...

introduction: several potyviruses infecting gramineous plants have been reported from iran. mosaic is the most widespread viral disease affecting sugarcane and maize production. sugarcane mosaic virus (scmv) is one of the causal agents of mosaic disease, which was first described in ohio in 1963. scmv belonging to the genus potyvirus, family potyviridae, is a single-stranded positive sense rna ...

Some members of the familyClavicipitaceae are endophytic and have mutualistic relationship with the plant family Poaceae. Their relationship is beneficial for both host and fungus. In the present investigation, endophytic fungi were isolated from seed and leaf sheath of hosts Festuca arundinacea, F. ovina, F. pratensis, Bromus tomentellus, Melica persica and Lolium prenne. Morphological charact...

The capability to utilize different forms of nitrogen (N) by sorghum (Sorghum bicolor), rice (Oryza sativa), maize (Zea mays), and pearl millet (Pennisetum glaucum) was determined in pot experiments. Seedlings were grown for 21 d without N, or with 500 mg N kg(-1) soil applied as ammonium nitrate, rice bran or a mixture of rice bran and straw. No treatment-dependent changes of root length, surf...

Straw amendment can improve soil properties and is an effective strategy to control soil-borne diseases. However, gramineous straw application vegetable fields has rarely been studied. In this study, rice was added the field of Chinese cabbage for one or two years (repeated), plant growth, disease occurrence changes in chemical were measured. addition, bacterial community composition analyzed u...
