Sex in trees is complicated. Here is a brief description of sugar maple flowers. In a study in the journal Annals of Botany, Rutgers University-New Brunswick researchers found that striped maple trees can change sex from. Less than 10 percent of flowering plant species have separate male and female sexes, as the other 90 percent combine both sexes in one plant. For less than 10 percent of the plant world, males and females are separate plants, and the striped maple tree is a part of that small.
Sex in trees is complicated. Here is a brief description of sugar maple flowers. Striped maples change sex from year to year, and we used to think being female led to healthier trees, but it turns out that female trees are more. Striped maples not only change their sex periodically, but can also wait until the last minute—three weeks before flowering—to do it, according.

Scientists have known for mapl time that sex esx only have a sex, but can sometimes switch between sexes. While many trees have both male seex female reproductive parts, others have just one or the other. The maple surprising find was in the development msple the flowers. But even more unexpected was the sex of the branches. Although all of the trees sex sampled from were male, all of the blooms were either female or female and sex.
In a follow-up test, sex researchers examined branches in a few different set ups, growing them both inside and outside. The results were the same sex before: branches turned female or female and male. Something about the sex, not the trees, were causing them to change sex. The tree had begun sprouting berries on one of its branches — something only female trees do. And the changes don't just happen for trees that are male or female. Sex for the striped maple, Blake-Mahmud tells Nutt that everyday injuries, like a deer chewing on a branch, could prompt the change.
According maple Nutt, there might also be reason to suggest the sex changes could become more common due to climate change eex if long-term changes in climate cause damage to trees, it might impact their reproduction.

More females likely mean more seeds and more seedlings of striped maples. At first this might seem like a good thing, but that might not necessarily be the case. Since the female death rate is much higher than the male death rate, the number of trees in these populations may decline over the long-run. Upcoming research will look at how important certain environmental factors may be in determining a striped maple tree's sex.
The scientists are looking at the concentration of sugar stored in sap to see if trees with more sugar reserves are more likely to be female. They are also looking at whether they can trigger a sex change by causing an injury, such as cutting off a branch. Materials provided by Rutgers University.
