    I agree with you the seed pod sometimes looks promising but when opened only white fibers without seeds at all...really frustrated after awaiting for few months.

    Many years ago I read, or maybe it was heard a talk, about what happened after pollination. Quite surprising that it is not instant in respect of the pollen gamete (maybe not right word ?)reaching the seed. First the pollen tube has to grow the length of the ovary, at least in respect of one end of the pod, and only then does the gamete travel along the tube.this apparently involves a cascade of different proteins, one after the other, essentially in a correct order, which means the genes invilved have different time switches for being brought into operation. And only afterthe gamete has got there, does it start to do its stuff. There is of coures a seperate tube for each grain of pollen, and for each seed. The easiest example of this is with corn on the cob, where all those silken threads which you strip away before eating, are the pollen tubes.
    This was research aimed discovering how soon green pod technique could be used to get protocorms.
    We know nature is wonderful, and the more we know, the more wonderful it seems.

    Now I know what those fibers and silken threads are. I have been wondering for so long.
