How Do They Grow Seedless Fruit?
Posted by admin on February 14, 2010
In some cases, they’re varieties of the fruit that have miniscule infertile seeds, e.g. bananas – the fertile banana has huge seeds filling it and is inedible. They reproduce plants like this by cuttings etc.
In other cases, like seedless grapes & oranges etc., basically, the flower is tricked into thinking that it’s been fertilised (with substances called auxins). Theis triggers the fruit into growing, but since the seed hasn’t actually been fertilised, it doesn’t develop. This is why seedless grapes sometimes have seeds in them, because an insect got to the flower and fertilised it before the farmer got round there with his chemicals.
