Ethylene evolution from 2-chloroethylphosphonic Acid.
2-Chloroethylphosphonic acid (CEPA. "Amchem 66-329", "Ethrel"; ref. 1), a new plant growth regulator, degrades to yield ethylene in an alkaline solution. When applied to plants, it has been very effective in causing responses characteristic of ethylene treatment (3, 4, 6, 7). The formation of ethvlene or its alkene homologs from CEPA or its homologs was studied and deFcribed in detail in 1963 b...
متن کاملtemporal changes in abscisic acid concentration in dormant and non-dormant seeds of wheat (triticum spp.) genotypes
little is known about the levels and physiological role of endogenous abscisic acid (aba) during after-ripening and germination. genetic variants for aba content were investigated to account for the role of aba in the persistence of seed dormancy. in this study, genotypic variation in aba contents at zadok’s growth stage 92 (zgs 92), temporal changes in aba during two physiological stages (...
متن کاملEffect of living mulches and conventional methods of weed control on weed occurrence and nutrient uptake in potato
The aim of the study was to determine the biomass, abundance and species composition ofweeds, as well as macroelement uptake in potato weeded using mechanical, mechanical–chemical and mechanical control combined with the sowing of living mulches of white mustard,common vetch, Persian clover and tansy phacelia. Abundance and biomass of the weeds was themost effectively limited by the mechanical ...
متن کاملAutomatic Identification of Weed Seeds
We explore the feasibility of implementing fast and reliable computer-based systems for the automatic identification of weed seeds from color and black and white images. Seeds size, shape, color and texture characteristics are obtained by standard image-processing techniques, and their discriminating power as classification features is assessed. These investigations are performed on a database ...
متن کاملRetinoic Acid Determines the Fate of Spermatogonia
In this review, we aim to examine the effect of extrinsic and intrinsic factors on spermatogenesis process taking into account a complex signaling pathway. Primarily, it is suggested that retinoic acid (RA) has a vital function in spermatogenesis process and it is considered to be essential for completion of spermatogonia into mature spermatozoa. In the present review, the key effects of retino...
