Crossing Pygmy Drosera...

20 years ago

After watching my pygmy drosera send up flower stalks last ... whenever they did, then catchng the odd flower open, or not, I began to wonder.

How the heck do you cross these guys?

The flowers are so microscopic and open for such a short time at odd intervals.. How is it even possible I wonder?

Seems impossible to me and yet I keep seeing things like "D citrina X D dichrosepala" around when I go looking for pictures.

Seems difficult to get a cross & I'm just curious as to how it's done.

    1¡¢ Brief introduction of TERNPC
    ¡°The technique of efficient & rapid non-test tube plant clone¡±(TERNPC) is a completely new system for rapid plant propagation, first invented by Professor Li Changxiao. Through a long-time practice, it has been proved to be an important breakthrough both in the tube rapid plant propagation of modern biotechnology and in the conventional seedling-breeding technique that has been used by mankind for nearly 2000 years.

    2¡¢ Characteristics of TERNPC
    The most significant characteristics of TERNPC can be described as low cost, rapid speed, high efficiency, considerable benefit and easily reaching large scale. This technology keeps the advantage of tissue culture and conventional ways. At the same time, it overcomes the disadvantages of them.

    3¡¢ The introduction of the inventor of TERNPC
    Professor Li Changxiao is praised as "The great master of green-coping" by the mass media at home and abroad. He is now the executive director of China Hi-new Technology Industrialization Research Association, member of the standing committee of the Hi-new Technical Expertise Committee of China Agricultural Technology Spreading Association, executive director of China Quality Inspection Association, chairman of the board of Ningxia Kelong Industry Company, head of Ningxia Kelong Bioengineering Development Research Institute. He has published more than 30 articles of researching, of which "the Technique of Efficient & Rapid Non-tube Plant Clone" is an example. He is one of the home scientists who began, earlier than others, to work on the research and development related to biotechnology. He is the first man, at home and abroad, who advanced the idea that "Rapid propagation is both a leading and a high efficient industry", and he is a famous scientific and technical industrialist who initiates and puts "the rapid pr

    *S* Ya I thought that was a cut & paste potentially commercial advertisement when I found it in my mail.. And after searching on "TERNPC" I found Their site where I read about the technique- Or as much as I could since nowhere does it HOW the plants are propigated.

    "At present, there are over 360 technicians who have been trained by the inventor Li Changxiao, or by his technical assistants. This has made the preparation for the need of personnel in the coming industrialization. It is estimated that the people who are engaged in the technical production next year will be 2500 or more"

    I wouldn't mind being one of those people.. But I highly doubt it's possible for me.

    Does look like a very interesting way to propigate.. Anything, really, especially if it can truly be done in the field rather than the lab.

    Hey there Krstofer,
    I think you guessed it when you said it must be done at a microscopic level.
    if is it a natural cross, and I haven't researched this subject enough to know if the D.citrina X dichrosepal is, then it would jest result from using the gemmea of the crossed parent.But if it is articially crossed , i think the pollen from drosera can be saved several days to be used when the plant starts to bloom.
    I haven't studied the pollination of pygmy sundews that much, but some of the larger ones are like the flytrap.that is: You have to put today's pollen on yesterday's stigma to get seed to set.
    Thanx for listening and keep 'em plants growin.

    Oh before I forget, I once asked Ivan Synder of D. X obovata "Ivan's Paddle" how he did his crosses and he jokingly replied, "I can tell you but then, I would have to Kill you."
    So those that are doing it are playing it very close to the vest.

    I just received an 'Ivan's Paddle. So this is a cross between an anglica, rotundifolia, and a what?

  • 20 years ago

    Ivan's Paddle is Drosera x obovata tetraploid
    [rotundifolia CA tetraploid x anglica (CAxHI)]according to a website. I agree that it is hard to fully understand, but I hope this helps.
