plant reactions to fire
I am proof-reading a text written by a Spaniard in English about the germination capacity of Euphorbia nicaeensis following a fire:
"In Mediterranean ecosystems, fire is a common disturbance (MORENO et al, 1998) and two types of plants have been described according to their response to fire: seeder and resprouter species (KEELEY, 1991). Generally, seeder species die after the fire and the seeds germinate in the first rainy season following the fire, since their dormancy is easily interrupted by a thermal shock or by products lixiviated to the combustion of plant material"
Can anyone tell me what he is trying to say here please?!
thanks

and thermal shock doesn't need an article, I'd say

Alfredo Tutino
: lixiviate = separate soluble from insoluble part (Concise Oxford Dict.). Rain can solubilize strongly basic material from burnt plant material - for instance, potash lixiviated from wood ashes was and is used in soap manifacture, e.g. for home use

Thank you Alfredo - and for the info. (n.b. dissolves)

Henrique Serra
: Sounds plausible... and "leach" is definitely better than "lixiviate", even in this scientific context.

Will Matter
: Merriam-Webster dictionary supports this, "lixiviate" (transitive verb), "to extract a soluble constituent from a solid mixture by washing or percolation". Water percolates through the burnt plant material, dissolves various substances, it's "lixiviation"

Richard Benham
: Yes, this is doubtless the intention. The original is badly ungrammatical. @Alfredo, rainwater does *not* "solubilize" alkalis, it dissolves them.
