We bought a red paw paw yesterday and want to grow some more so kept the seeds to plant. There are some white and some black seeds. Can someone confirm the white are immature and can be discarded?
All the books I have read indicate there are three types of trees - male, female and bi-sexual, and that regardless of the type of tree you get seeds from the seeds will be a mixture of all three and the only way to tell is to wait for the plant to flower. As males don't produce fruit at that time you cut down the males (leaving one for eight females) and sometimes they will revert to female.
When asked to confirm a bi-sexual seedling, an ebay seller advised me:
Hi - there are a few different types of bi sexual paw paws- some fruit from close too the trunk and some yellows I have fruit from what looks like male flowers and I remember when I first saw mine doing that umpreen years ago I thought oh no it has ended up being a male-- but has the fruit in clusters - nice sweet ones- so ina ctual fact there are many different ones that grow and fruit different- it is also said by many that all bisexual are only red but this is not so- a lot I have I get from someone that grafts them-- which I have had on from time to time- but I do only have bi sexual and do not allow any one tobring others in in case somehow they do end up in the compost etc--- but it is true a small percent can end up being non bi aand female or male- I have heard this not seen it myself- usually the pink hue on young stems is a tell tale sign I believe
So can anyone confirm that bi-sexual trees tend to produce mainly bi-sexual seeds, in which case I should wait for my own bi-sexual paw paw and use those seeds...
