Nitric Acid Content

Kyzylkum phosphate rock was studied with a nitric acid content of 50 and 75 and 100%, as well as in fertilizers obtained from the ratio of R2O5: K2O = 1:1. The gyroscopic points of the fertilizer size of 2-3 mm were determined at 250 ° C by the desiccator method of N.Ye. Pestov. The points of hygroscopicity of fertilizer samples with an initial moisture content of 1.0% were No. 1 - 46.5%, No. 2 - 38.0% and No. 3 - 32.4%.

Thin Sections

Schumacher and Halbsguth first demonstrated ectodesmata as pores or channels in the epidermal cell walls in haustoria of Cuscuta odorata L. by light microscopy in tissues fixed in a sublimate fixative (30% ethyl alcohol, 30 ml:glacial acetic acid, 10 ml: 65% nitric acid, 1 ml: 40% formaldehyde, 5 ml: oxalic acid, 2 g: mecuric chloride to saturation 2-3 g). Other workers have published electron micrographs of structures transversing the outer epidermal cell in thin sections of plant leaves that have been interpreted as ectodesmata. Such structures are evident following treatment with Hg++ or Ag+ salts and are only rarely observed by electron microscopy. If ectodesmata exist without such treatment, and are not artefacts, they would afford natural pathways of entry for applied foliar solutions and plant viruses.
