1. What determines the sex of a plant? (I'm sure this answer differs from one class to another.)

| The only one I can speak to is #3, and that on mighty slim evidence. I once grew 8 papaya seedlings in a large greenhouse. 3 had only female flowers, 4 had only male, and two had only hermaphrodites. Got lots of fruit of variable quality, all with lots of seeds, during that brief "mini-experiment". That experience gave me the impression that sex in papayas, at least, was genetically determined.

| 3 + 4 + 2 = 9 What happened? Did one die? |

| Lawsy! How did I manage to get through college without knowing how to add or proofread?! Sorry, after I checked my "mental records", it was only 3 males. One of the hazards of having an almost eidetic memory, and 10 years difference in time. Sigh, I guess you might want to wait for a little more documentation. |

| I was thinking more about the ones that have male flowers one season and hermaphrodite flowers the next. Meilie had one, I think. These two articles appear to have a common source that says it's probably the weather, and I suppose that makes more sense, because I've also read that hermaphrodite papayas take on masculine or feminine features depending on weather conditions. I still haven't met anyone who actually tried cutting the head off a male papaya or driving metal nails through the trunk to cause a sex change. Does anyone here know if that actually works? |
