摘要: Abstract Cotton (Gossypium hirsutum L.) is extremely sensitive to Al toxicity. Increasing Si concentration in solution has been reported alleviate AI In this investigation the effects of varying concentrations (700, 1400, and 2800 μM Si) on reactive (defined as with aluminon during 10‐s reaction time, without acidification heating) was studied solutions containing either 50, 100 or 200 50 d aging. An increase had negligible Al. However, decreased by 6 15% an from 0 μM. The 700, 1400 root growth Coker 208, 315, DPL 90, McNair 235, Stoneville 506 Tifcot 56 cotton cultivars were investigated 0, 10, 20 40 500 Ca at pH 4.5. no Al, addition 700 improved by...
