Dd. Faye et al., PHYTOINHIBITION PHYTOSTIMULATION POTENTIALS OF SYSTEMIC INSECTICIDES ON TISSUE-CULTURED COTTON (GOSSYPIUM-HIRSUTUM) CELLS, The Southwestern entomologist, 20(2), 1995, pp. 151-156
Tissue-cultured cotton calli of the cultivar Coker 312 were exposed to
three systemic insecticides at three field rates (converted to labora
tory equivalents) for 8 wk to evaluate the effects of phytostimulation
or phytoinhibition on cell phenotype (coloration) and fresh and dry w
eight production. Phytotoxicity was observed at the highest label fate
of each chemical. used. The stimulatory effect found at the lowest ra
te resulted in significantly higher fresh-weight and dry matter accumu
lation; whereas, inhibition at the high rates, due to phytotoxicity, r
esulted in significant reduction of cell mass production.
