Allium is the largest and important representative genus of the alliaceae family and comprises 450 species, widely distributed in the northern hemisphere.Shallot allium cepa var aggregatum don.2n16 is an important vegetable crop belonging to the family liliaceae.It is originated in tropical central or western asia and has been cultivated from very early period.
Onion allium cepa l.Is the second most important vegetable crop in burkina faso and provides an important source of income for those involved in the sector.However, producers are facing significant pre-harvest and post-harvest losses.To date, knowledge of major diseases of the crop is limited, limiting the development of effective control strategies.
C 1 is the chlorates concentration of the inlet stream which we assume it is zero or very close whereas c is the chlorates concentration of the outlet stream, which varies with time and equals the concentration inside the tank if it is perfectly stirred.We have to identify the sources of production or depletion of chlorates in the solution.
The phytotoxic effects of te tested on allium cepa and lemna minor revealed inhibition of root growth and significant reduction in number of fronds, protein, and chlorophyll content.Moreover, te induced chlorosis and tissue necrosis in nostoc muscorum at low concentration 10.
