    Drosera adelae and Polyploidy.[Giant pictures]

    Today I began an experiment with D. adelae and what they do when they're polyploid. For those that don't know, polyploidy is when an organism has more than the usual number of chromosome sets, such as twice as many, four times, etc. For this experiment, adelae root cuttings were exposed to .1% oryzalin for 24 hours and we're gonna see how they grow differently than normal ones.
    Brick of red/green sphagnum moss. Not looking to happy right now.

    Fluffed up now. Right is control tray.

    The D. adelae roots that are being used.

    Drosera adelae cuttings in their petri trays. The others are fast plants, as we're experimenting with them too. I had to count all those seeds by hand, no tweezers. Not fun because static would make them roll away,

    Everything soaking. Tomorrow we rinse them and get them in the proper substrate. Orange is experimental.

    Sounds like a cool experiment. I'll be looking forward to your results.

    More on it tomorrow when I we get them planted in the moss.

    Have you ever done an experiment like this before? Any idea what to expect?

    Generally polyploids will have thicker leaves and bigger flowers. It's not always a good thing, mind you, but sometimes a polyploid will benefit by essentially being able to "harness the power" of that second set of chromosomes. Polyploidy can render them twice as effective at doing many biological functions.

    I've done this experiment before with the Capsicum chinense chile peppers, and got some very odd shaped leaves. The polyploids aren't simply twice as massive, and in this case at least they were disproportionate and/or deformed.

    I'm hoping the Drosera adelae get larger, and I'm also going to be measuring how their stickyness varies. Also, if they get larger than the normal ones that would explain a thing or two about that giant adelae that appeared recently.

    The main thing I'm studying is reproduction though, which is divided into two parts. The first is if polyploidy effects their willingness to create plantlets, so I'll be measuring crown count between the control and experimental. The second is if polyploidy interferes with their self incompatibility(this is documented in the past for other plants), so I'll be pollinating the polyploids to see if they produce seeds with each other and with the diploids, which shouldn't be happening for adelae.


    Below are two leaves from two different plants I had last year.
