Scaring a tree into producing fruit?

Has anybody heard anything about this? I just heard about it today, from my sisters and my aunt, and to me it seems like the stupidest thing I've ever heard.

I just heard about it today, from my sisters and my aunt, and to me it seems like the stupidest thing I've ever heard. Everybody I talked to about it seems surprised that I didn't know about it: if a tree isn't producing any fruit, you can threaten to cut it down, and that'll solve the problem. Apparently it also works if you talk nicely to it, but of course I'm the only one who's never heard of that either. With no amount of reasoning could I convince them that a plant has no understanding of what you say to it. It seems clear as day to them that any living thing can hear and understand. Anyway, has anybody else heard anything like this? I just thought my aunt was superstitious, but it seems to be "common knowledge" around here. They even claim that scientific research has proven it. Of course, I don't believe them; and a lot of scientists are idiots too. All I can say is, wow.
