I wonder if the following information might be of help when taken into 
consideration with the others.

Firstly I would suggest it is fair to comment that plant growth is a 
response to a variety of factors, these are further modified by whether the 
plant[s] in question are in general terms native to [a] arctic/alpine zones; 
[b] boreal zone; [c] temperate -northern or central; and those for which I 
have no experience such as [d] mediterranean and [e] arid or desert zones.

In respect of [a], [b] and [c] above it is the case generally that onset of 
growth, particularly trees and shrubs, is governed by  8 degrees Celcius x 
Xdays of 8C.  the value of  Xday is a variable due to several factors such 
as latitude, altitude and continentality, however rainfall patterns will 
also have an effect. To use Silver Birch - Betula pendula (Roth) as an 
illustration, the most northerly stand of any tree species are those found 
growing at North Cape in North Norway. Betula pendula grows there and the 
trigger for it to achieve bud break is shall we say Xdays x 3 in order to 
get a fast start with onset of spring in a climate with an incredibly short 
growing season. However, this tree species also grows in Spain north of 
Madrid where the trigger for onset of growth could be Xdays x 12. Therefor 
if trees are grown from seed from the first location at at almost any point 
further south in a cline towards the Spanis location there is an increased 
risk as it goes further south of being induced into growth too soon and then 
to be damaged or even killed by frosts at that location. As a general rule 
in Europe, seed from any species should not be moved further north in 
commercial forestry by more than 2 degrees north before the benefit of extra 
growth/yield is risked by increased incidence of frost damage. I suspect 
that the points noted belwo for Lilies my have an analogy with the Birch. 
Until it is tried we wont know.

This is one of the investigations which I am undertaking in relation to my 
book on; Lilies and their allies, Cardicrinum, Lloydia, Nomocharis and 
Notholirion. Here at circa 58 degrees North I expect to have virtually all 
the species lily to record data on, germinability, optimum sowing time such 
as autumn or spring, ambient temperatures and humidity as well as day 
length. I am also intending to record times of onset of growth, time to 
flowering, time of flowering, duration of flowering and onset of senecense 
in the autumn = your fall. For a smaller cohort of species this will be 
replicated with the help of others, one each hopefully in Russia and China, 
plus at least one location in north America, preferably two, i.e. one west 
one east. All of the replicates will clearly be at more southerly latitudes, 
but have other variables such as weather and day length. From this we should 
all learn which species we can work with safely wherever we live. It will 
also hopefully aid the horticultural industry to evaluate where to take 
their work and with what species, or what species to avoid, If it doesn't 
work out then I will have had the pleasure of working with beautiful plants 
and interesting generous people who have participated.

In terms of improved germination, seeds are most likely to be successful in 
germination if the species comes from areas [a], [b] and [c] above if they 
have a chance to be vernalised, i.e. subjected to freezing and thawing as 
would happen in their natural habitats. In arid regions I am assuming this 
is analagous with dry season - rainy season. All plants must have a rest 
period if they have evelved outwith the tropics and even there there are 
permutations of the above but not of interest to those on this forum.  Jane 
McGarry has the right idea interms of adding snow to the pot but not for the 
reasons offered. Another route would be to put the seed, mixed perhaps with 
peat of sand into a freezer bad and placed in the fridge at c. 0-2C for a 
couple of weeks, out for a couple to warm up to ambient outdoor temp, then 
back in for however many times it is convenient and necessary. As a rule 
here at Auchgourish botanic Garden in the central Scottish Highlands seed is 
sown as soon as it is collected or arrives from others or botanists working 
in nature. That way vernalising takes its normal course.

One little wrinkle to watch out for amongst e.g. some lilies and arisaema as 
these have a different strategy in that they produce their bulb or corm 
under ground in the first year before poking above ground in the second. I 
know this because I have fallen victim to the trick but I do get there in 
the end, however slowly.

Regards, Iain

PS. I believe an American man called Dirr has published book[s] on seed 
germination, it might pay to check it out.
