Kind regards La Palmeraie Hi Jules

Can I transfer pollen from one flower to a different one (an older one to a younger one) to produce successful fertilisation and seeds? I tried it last year with no seed production.

The document you shared by mail is the same as the url which doesn't specify any further the exact order of ripening of the Strelitzia flower. As for all my articles, I do some serious research in reliable publications only, before stating whatsoever. I spent quite some time last weekend digging into this specific question again but to be honest, I still didn't find a clear answer. I did find another article that stated the order of ripening as I did. First the pollen and then the pistil. As I said, I think it is very important to publish correct information only and I did do my research back then as well. Very little information can be found but to clear this one out once and forever I contacted the reference on this subject, the Kirstenbosch National Botanical Garden in South Africa. If necessary I will correct my article of course and I will keep you updated as well naturally.  I do not think that my article does "mislead" my readers as you stated. I had many positive reactions since the first publication back in 2011 (for the dutch and french versions) from readers that did succeed the hand pollination due to the article tips. It was also one of the first to have a clear and simple description of the flower's anatomy with pictures. The article also does state that the flower can't pollinate itself and that you need another plant to effectuate the pollination but if the plant is potted with other subjects (as is often the case here) you may be able to do so.  Kind regards La Palmeraie Hi Ian

My response was not to simply point out technicalities. (Indeed, I wrote “pistil” when should have written “stigma”) The article was unhelpful in that readers could be misled so as to attempt to pollinate before the pollen was ripe. In each flower the stigma is receptive before the pollen is ripe not vice versa. Furthermore your readers may be led to believe that if they had only one plant that that would necessarily preclude fertilisation following hand pollination.

For those that aren’t familiar with these biological terms, it’s all about what is ready first; the pistil or the pollen. In fact there is very little information available on this specific subject and your url links to a Chinese database, not readable for me I’m afraid. If you have other resources I would be more happy to take knowledge of them! This said, for most readers it’s all about how to pollinate the flowers at home so this discussion is rather irrelevant but ofcourse I do want to publish correct information only. Kind regards La Palmeraie Hi Ian

The pistil becomes receptive to pollen (i.e. sticky) soon after it emerges from the spathe. At this stage the pollen is not readily removed from the anther. While this does prevent fertilisation of each flower with its own pollen, strelitzias are clumping plants that when well established produce several flowers whith some at different stages of maturity. Hence can produce seed geitonogamously.However this may be very limited in nature given the comparitively small amounts of pollen likely to be transfered between flowers and apparent subsidiary biological mechanisms that inhibit self-fertisation. http://en.cnki.com.cn/Article_en/CJFDTOTAL-BJLY200102010.htm Strelitzias are protogynous(protogynic)not protandrical.
