in situ a lot of them are naturely green , just some one are born red .

the sun increase the red colour , activate the "antocyanate" and the "carotene" into the botanical cell , it is a normal reaction to the UV.

here in FRANCE with a naturel light ( just the morning sun ) you have this red color *biggrin2*

Re: for the road
 

YOU mean UVA or UVB? Do you think that a P.emarginata x 'weser' will get any colour? Thanks :D

Re: for the road
 

in situ you have 3 UV differentiated by their wavelength

UVA:320 to 400 mn
UVB:290 to 290 mn
UVC : <280 mn Stopped by the check mark ozone

the UVA here are dangerous all the journey
the UVB just form 12 to16 h they are more dangerous because the more penetrating than UVA

for me the morphological standard from x'Weser '( the real) and emarginata for the leaves are green.

now if they are invariably in the sun they will even turn pink or red *biggrin2*

Re: for the road
 

Oh thanks:2thumbup:. Do you find out which UV makes plants grow? Is it UVA or UVB?

Re: for the road
 

for a 100% radiation incident on a plant:

you have 42% for infrared,4% for the UV ( all) and 54% for a visible light
for infrared: 45% to 42% used to sweating
for the visible light : 27 % for the plant , 1% for the photosynthesis ,the others reflected

I think that's how it happens,but I may be mistaken

Dear Jeff,

Thank for the sharing.

Now I just know why my Pinguicula change colour from Red to Green and from Green to Red when I move it from 1 place to other.

Thank you

Re: for the road
 

did you get flower on your mexican ?

Re: for the road
 

Dear Jeff,

Yes. But do not have seed.
Any idea on how to get the seed if I only have 1 type?
As my understand, we needs to cross pollination (2 family) to the seed.:shy:


Thank you
