The selective weedkillers contain growth hormones, that cause the weeds to grow really quickly. This means the weed is absorbing nutrients from the soil at a much higher rate, and so the weeds absorb the weedkiller in much larger quantities than beneficial plants. This can be used for getting rid of weeds without killing the grass, or thistles in a field without killing the crop. Plant hormones can also be used in controlling fruit ripening. In nature, plants only germinate when conditions are ideal for growth. This is called seed dormancy and is controlled by hormones. We can use hormones and inhibitors to remove the dormancy of seeds, thus enabling us to germinate seeds at all times of the year. We can also use these hormones to make plants grow bushier and make them flower at controlled times; exactly what you want if you are entering a flower show! Ethylene is used to ripen fruit. Ethylene breaks down components of the cell walls to make them softer, and makes them sweeter by converting starches to sugars. Ever wondered why you are told to put unripe fruit next to ripe fruit? Ethylene is different to other hormones because it is an airborne gas, and works on a positive feedback loop. Start with a little ethylene, and this causes more to be released, which causes more to be released… and so on. Therefore promoting ripening in all ‘local’ fruit.
