Cyclamen

Postby Satureja » Mon Feb 07, 2011 2:07 pm

Hi!
My name is Gaia and I am an italian girl with a degree in Biology.
In my country there isn't a lot of this type of forums in which we can talk and share information to each other so when I find this one I thought that I can join you and share some ideas, ask some opinion and so on.

I wrote in this section because I want to see if someone could help me with one thing that I find very interesting but I can't find any kind of information about it anywhere.

As a biologist I love nature and I love to go on long walks (expecially with my dog) and during these walks I watched every single plants and insect that I run into. :roll:
My attention was captured by the Cyclamen's (Cyclamen europaeum Mill.) leaves.
All the leaves that I see have light spots on the superior surface and that spots are different for each indivudual: some leaves are almost green and some have big light spots all over the external part of the leaf.

The first thing I thought was: why there is such a difference between the inviduals? It can't be like animals, in which the pattern of the spots is useful for the interspecies recognition, so what the meaning of this?
Maybe is just a random pattern causes by genes.
But after that I started to think and I came up with more questions..What is the cause of f the spots? I mean, at cellular level, or tissutal level what causes the light spot on the leaf? Is the absence of chlorophyll in that cells? Or is the absence of the cells which contain the cholophyll?
But the spot is not really "white", is more "light green" so maybe is not the complete absence of chlorophyll, but maybe the color depends on the thickness of the cellular wall.

I try to find out in some books that I have, but unfortunately I can't find anything about it.

My big question is: Why the cyclamen's leaves have spots? What is their function? Is somehow related to the quantity of light that came in the brushwood? Or is used to send a message for the animals, so they don't eat the cyaclamens because maybe they are toxic for the animals.

I really don't know and I'm very happy if someone knows somenthing about it and tell me!

I'm really sorry if I made grammatical, syntactical or any other kind of mistakes bu I'm italian and I have not such a good command of the language, so please forgive me if you find something wrong!! :?

Thank you!!

Hello Gaia
My name is Ozan
Firstly, I cant understand what do you mean with spots at cyclamen leafs.
I found something and I want your confirmation if your cyclamen it is

If your cyclamen's leafs are like that ,we can be closer your question's answer.

Hi Ozan!
It's difficult to explain what I mean with spots on the leafs, even in my first language so I try to explain that with a picture

When I look at the leafs I can see that part of the superior page is dark green and part of it is light green, and this light part can form a sort of 'drawing' but I don't know how to call that so I tried with 'spots'.

I hope you understand what I tried to mean!

thank you for your answer!

Cis or trans? That's what matters.
