[Terrapreta] Charcoal and Salicylic acid

[Gerald Van Koeverden]

Never heard of this aspirin effect on plant growth.  I scrounged this  
research article on salicylic acid as a phytohormone off the  
Internet.  According to these researchers, aspirin induces the plant  
to override stress-induced inhibition of growth. Thus it seems to be  
like cocaine allowing the Inca runners to keep on going without  
feeling tired on their long communication hauls...

Summary. We investigated the effect of salicylic acid (SA) on plant  
resist-
ance to environmental stress factors. Treatment of wheat plants with  
0.05mM
SA increased the level of cell division within the apical meristem of  
seedling
roots which caused an increase in plant growth. Phytohormones are known
to play a key role in plant growth regulation. It was found that the  
SA treat-
ment caused accumulation of both ABA and IAA in wheat seedlings. How-
ever, the SA treatment did not influence cytokinin content. We  
suppose, that
the protective and growth promoting effects of SA are due to the  
phenomenon
described above. The SA treatment reduced the damaging action of  
salinity
and water deficit on seedling growth and accelerated a restoration of  
growth
processes.Treatment with SA essentially diminished the alteration of  
phyto-
hormones levels in wheat seedlings under salinity and water deficit.  
The SA
treatment prevented the decrease in IAA and cytokinin content completely
which reduced stress-induced inhibition of plant growth. Also, high ABA
levels were maintained in SA treated wheat seedlings which provided the
development of antistress reactions, for example, maintenance of  
proline ac-
cumulation. Thus protective SA action includes the development of  
antistress
programs and acceleration of normalization of growth processes after  
removal
stress factors.
