You can't. Because cells are the basic unit of the structure and function of organisms. If glucose in plants wants to be used, it must undergo a chemical reaction in cells. We inject glucose into plants, but not into cells. Moreover, due to the injection of glucose, even a small amount will increase the osmotic pressure of extracellular fluid, which will lead to dehydration of plants.

To sum up, this practice can't help its growth accelerate. On the contrary, it will harm plants.

I hope I can help you.
