Palmer Amaranth Extracts. The aqueous extracts made from senescent Palmer amaranth leaves and thyrses after seed development and dispersal had little effect on any of the seeds tested (Table II).

Antimutagenic activity. Ethanol (70%) extract of the dried aerial parts, on agar plate, was inactive on Escherichia coli PQ37 vs mitomycin-induced mutagenesis, assessed by the SOS-chromotest method Antioxidant activity. Hexane and methanol extracts of the dried seed, tested on lard at a concentration of 0.06 %, were inactive Seed oil, at undiluted concentration, was active " . Acetone extract of the seed, at a concentration of 0.2 mg/kg, was active. Linoleic acid was used as a substrate in this test " .

The consequences of phosgene exposure for seed germination have been investigated by Neifert and Garrison (see Table 2.10). There was a deleterious effect on most seeds tested, in particular, muskmelon, wheat and millet. However, it did appear to have a slight... 

For mineralization, the normal, metastable state is adjusted by nucleation, measured by the seed and solubility tests. The seed test measures amount of solid apatite required to precipitate Ca2+ and HP042- ion concentrations exceeding their solubility product. The solubility test measures the minimal concentrations of Ca2+ and HP042- necessary to induce precipitation. Type I collagen fibers nucleate bone formation as the concentrations of Ca2+... 

Water content of isolated embryos (Figure 42.1d-e) was determined by the oven method at 103 2°C for 17 h (International Seed Testing Association, 2005). The results were expressed as the mean content obtained from three replicates.

Metham is used for general soil disinfection, in greenhouses and under field conditions at a rate of 11 litres of the 32.7% solution per 100 m. At this rate it kills all plants and seeds, thus the planting of crops must be delayed for about 2 weeks after treatment. The termination of the phytotoxicity of treated soil must be checked by the cress-seed tests.

Because of the possibility of reversion or the presence of volunteer high erucic acid material, the standards for erucic acid level in certified seed have been much lower than the level accepted for food use. Table III outlines the erucic acid levels in certified rapeseed as well as the average value found and the percentage of seed tested meeting the standard.
