Aluminium/silicon interactions in conifers
Aluminium/silicon interactions in conifers.
However, no hydroponic Al/Si interaction experiments had been conducted, and so co-deposition may just have been a coincidence! Michelle Ryder helped to fill this gap, and produced this paper on the topic:
RYDER, M., GERARD, F., EVANS, D.E. & HODSON, M.J. (2003) The use of root growth and modelling data to investigate amelioration of aluminium toxicity by silicon in Picea abies seedlings. Journal of Inorganic Biochemistry 97, 52-58.
My next research student, Subramaniyam Prabagar from Sri Lanka, continued this work on in collaboration with David Evans (Oxford Brookes). We wondered whether the amelioration that could be observed in whole plants also happened in cell suspension cultures:
PRABAGAR, S., HODSON, M.J. & EVANS, D.E. (2011) Silicon amelioration of aluminium toxicity and cell death in suspension cultures of Norway spruce (Picea abies (L.) Karst.). Environmental and Experimental Botany 70, 266-276.
The answer is yes, at least under some conditions!
