photosynthesis

[SteveBullman]

been doing a lot of reading up on this lately and i have one question that none of my books seem to answer.
do trees containing caratenoids and anthocyanins photosynthesize as efficiently as a tree containing mainly clorophyll. and if not should this be reflected in the percentage of the crown you can remove at any one time.

i might just be missing the whole point or something.

All I know is that CO2+H2O will produce C6H12O6 and O2 given off as a gas.

I just need beans to accomplish that.

 

[jimmyq]

I think yer thinkin bout CH4 , Methane... beans beans the musical fruit, the more you eat the more you too. thats what the kids say around here

 

[SteveBullman]

fascinating about the beans lads, but sod all help to my question

I'm not sure what you're going for here. Carotenoids and anthocyanins are responsible for the changing colors in leaves which show up in the fall as photosynthesis slows. Are you suggesting that we should reduce pruning in the fall because of reduced photosynthesis? Orr wutt?

Maybe it would be acceptable to remove more canopy because of this?

I'm not sure, but I think they probably do. Since the other pigments don't show up very strongly until the chlorophyll leaves in the fall, I'm guessing they're not in the way of photosynthesis during the growing season.

I don't see a connection to pruning dose here.

no, what im saying is....and ive probably misunderstood the whole thing as i said in my original post....but anyway, im referring to trees which dont have green leaves such as purple plum, copper beach etc. as i read it their clorophyll are masked by the different coloured pigments, in which case are they prohibiting the green pigments from doing their job
with me now?

Stephen,

Unless your trimming tomato and carrot plants you don't need to worry about the efficency of Carotenoids. Carotenoids are and orange/red/yellow pigement. In leaves the amount of chlorophyll completely masks and amount of the caotenoids until autumn rolls around. Thats what produces the beautiful colors of the fall.

Anthocyanins fall in the middle of the other two. They provide the purples/blues/red.

Think of it this way

Chlorophyll>Carotenoids>Anthocyanins.

Not really sure what you asking, but you dont need to worry the amount of carotenoids and anthocyanin in relation to trimming trees.

steve i havent got a clue what your on about ,but i will soon ..what books have you been reading ???..are you refering to the way broadleaf /deciduos trees transfer light to sugar compared to the way coniferous trees do ?

 

[SteveBullman]

wheres nickrosis when you need him


rolla ive been reading about 4 books, the most in depth is Botany for degree students by A C Dutts
also Botany for gardeners by Brian Capon
the isa cert guide briefly touches on it also

 

[ROLLACOSTA]

you still thinking about doing a degree or diploma i remember you mentioned it..i have thought about doing an on-line degree

 

[SteveBullman]

the one through myerscough college you mean?? think they are the only ones who do the online degree last i looked
thats the one im thinking about doing.

 

[ROLLACOSTA]

to behonest id rather go to a college or uni 1 day a week..for umpteen years..on-line seems a bit too much hard work for me..i have also thought about another higher academic course than i have now ,trouble is our local colleges offer not a lot part-time

 

[SteveBullman]

what you got now then

mail box is full rolla

Mr. Bullman asks:

"Do trees containing caratenoids and anthocyanins photosynthesize as efficiently as a tree containing mainly chlorophyll? And if not, should this be reflected in the percentage of the crown you can remove at any one time?

I've often thought about that meself. I think this short article gives the answer to both questions.

my interpretation

my interpretation was that plants with green foliage had chlorphyl that absorb ed every other colour except green thus reflecting greenlight and appearing green.

plants that appear other colours do so because the chlorophyl absorbs different wavelengths of light and reflecting the said colour. so copper beeches would absorb every other colour except purple (opps i mean copper )

or have i missed the point as well (along with everyone else)

rolla i was looking at that online degree.....how many years long is the waiting list??

i was looking for a masters somewhere but i feel i should maybe develop a degree in arb first to give me better grounding (i have a degree in countryside management, and i aint no countryside ranger)

edit....most of what i said has been said in that article (which i read afterwards)

mike you hack

mike you hack whats a 'laef'.

do you get blue leaves anywhere? if so does anyone have a picture, or shall i wait for Butch to google it.

[jamie]

aye

cant really think of a reply, but there is some crap on the telly trying to sell us the timelife classic country hits of the 60s in the background.....must mean that its time for bed and not talking photosynthesis...

oh and any blue leaves? according to ask a scientist clue light is required for photsynthesis where as other lwave lengths are not as important...

hence no blue leaves, sorry laeves
