rosolis76 Posted May 10, 2005 Report Share Posted May 10, 2005 Hello, I would to know how to get seeds when Byblis rorida is flowering. It is self-fertile? Must I use a diapason like Byblis gigantea, or a brush? Thank you for your answers... Regards, Damien Quote Link to comment Share on other sites More sharing options...
vic brown Posted May 10, 2005 Report Share Posted May 10, 2005 I use a tuning fork to get the flowers to release pollen and a paint brush to transfer it. Is a 'diapason' a tuning fork? I don't self my plants, but transfer pollen between different plants to maintain genetic diversity and vigour. Seeds from last years harvest have proved very viable and easy to germinate, with a little help from GA-3. Vic Quote Link to comment Share on other sites More sharing options...
rosolis76 Posted May 10, 2005 Author Report Share Posted May 10, 2005 Thank you very much for informations Vic. But I have only one plant, so I can not maintain some genetic variety... If I use a tuning fork (sorry, it is a translation from the dictionnary ) to get pollen and fecundate the same flower, could I hoppe to get some seeds?

Andreas Fleischmann Posted May 10, 2005 Report Share Posted May 10, 2005 Hi Damien! I do not want to let you down, but please don't be too optimistic to get seed from your B.rorida if you have only one single plant flowering. Out of the different species and local varieties of northern Australian Byblis I grow, I made the experience that only B.liniflora can be selfed (and even this one has some local forms that do not accept their own pollen), all others (B.filifolia agg., B.rorida and B.aquatica) had to be cross-pollinated for me, i.e. you needed at least 2 different plants of each species to get viable seed. But you should try it nevertheless, maybe seed set is dependent on growth conditions? Please keep us informed whether you got seed or not! I'm using a toothbrush to scrap the anthers of the plant ("upstream", pollen is catapulted out of the apical pore of the anther tube when stamen are bouncing back), there's a lot of pollen released which can easily be collected and detected by placing a dark piece of plastic/paper underneath the flower. You will notice that pollen grains will only cover a small area on the collecting device (a spot of maybe only 1cm in diam., in case you did move neither flower nor collector! ;-)) but highly concentrated at its center! You can imagine that this way of "buzz-pollination" (naturally, anthers release their pollen load due to the vibration caused by the insect pollinator's buzzing) is very economic, pollen loss is reduced to a minimum as only a small spot on the pollinators back or abdomen is covered. And that's were pollen is taken up by the stigma on the next flower.... Good luck, Andreas Quote Link to comment Share on other sites More sharing options...
rosolis76 Posted July 6, 2006 Author Report Share Posted July 6, 2006 Hello Andreas, Thank you for informations. Unfortunatly I didn't get seeds:-(. Indeed I think the plants have to be cross-pollinated...My single plant of Byblis rorida is for several month dead now but I will try another experience if I can find seeds. Kindest Regards, Dam Quote Link to comment Share on other sites More sharing options...
