    Re: Touching them makes them hard...

    I agree with you all, I am sure the plants need some aggression (hot sun, wind, touching hand...) to help them becoming stronger, it's just a response to the aggression.

    Re: Touching them makes them hard...

    Reviving a bit of an oldie, but in the science world we call this thigmomorphogenesis. Thigmo (Touch) morpho (shape) genesis (create). Plants respond to touch in nature as well as captivity. Look at the roots of wild trees exposed to prevailing winds and you'll see the roots are longer on the windy side, strengthening the plant by "pulling" it into the wind. This is very true and requires little belief as it happens to every plant in nature.

    I assume that by tricking the plant hormones (which is what you are essentially doing) into strentghting the stalk, you are potentially robbing yourself. The plant might put more emphasis in withstanding the external forces and less in leaf production. Although, it might spur the plant into a rapid growth, which would require more nutrients to sustain the growth.

    the first part is understood. The second is speculation.

    All you have to do is touch my leaf
    To show me you mean no grief
    And something happens to me
    That's some kind of wonderful
    Any time my auxin world is blue
    Circumnutation just might locate you
    And every thing seems to be
    some kind of wonderful

    Re: Touching them makes them hard...

    Plants are very sophisticated when it comes to experiencing the world and communicating with each other and other creatures. From what little I have learned it appears they experience/communicate almost entirely through chemical signals (finding food, recognizing close genetic relatives, predators, friendly insects etc...).

    If we actually touch the leaves it likely does have a strong effect, they probably recognize our chemical signature and decide whether we are friend or foe out to eat/harm them or beneficial.

    I had to thin some seedlings in trays the other day and felt guilty about it, I also wondered if the plants saw me as an evil threat afterwards if they perceived me killing all of the other seedlings in the tray with scissors. Next time will scatter fewer seeds as it made me feel bad to cull the extras.

    Here is a documentary on their experience and communication. At the 16:00 min mark it talks about wild tobacco and how sophisticated it's system of perceiving threats is.

    It's probably not particularly useful to anthropomorphize plants.

    I am not overly fond of humans therefore I do not anthropomorphize. However if an organism reacts to threats they are by definition conscious.

    And I will agree it has a downside, especially when it comes to thinning seedlings or harvesting.

    I understand that there are different ideas about what constitutes consciousness, but pseudoscience and hallucinogens aside, psychological research points to the neural pathways in the brain that form short term memory.

    Re: Touching them makes them hard...

    "Threat" is a cognitive construct assembled from a constellation of present stimuli and memory. Without a central nervous system, an organism cannot perceive "threat", but may perceive stimuli. An amoeba reacts to noxious stimuli. It is not conscious.

    My tobacco grows wonderfully, despite my unkind habit of smoking a cigar while I tend the plants.

    I've seen some odd threads before but this one is just getting weird.
