[Terrapreta] Plant reaction to stress

[MFH]

Nikolaus,

There are different reactions in plants subjected to (a) long-term
continuous stress like drought, and (b) sudden shorter-term stress like a
bushfire.

In both cases the initial reaction will be to try and produce more
offspring, normally by increased flower and seed setting. In the case of
long-term stress the plant will make a decision that it doesn't have the
resources to handle this, and most flower/seed development will cease.

Even in the case of short-term stress, a stage will come where the plant
somehow understands that it cannot bring all the set fruit to maturity and
there will be a partial shedding of fruit. This is common even without the
stress incentive.

Dear SEAN,MFH!

A small but essential correction,plants when under stress under a continuous
(nutrient and other limiting factors taking in a count) inventory, decide
to abort flowers, onset of fruits and half developed fruits to guarantee
that the remaining off springs have good quality and are viable reservoirs
of there genes. They do not rise seed production under stress, in contrary.

Plants do not have a selfish, individual centered live , they always
concentrate on the survival of the species.This is better done with less but
well developed seeds.The human being is the only species, that reproduces
with the focus that the children might sustain their parents in case of
crisis. In plants, this never would happen.

Best regards Nikolaus
