scientists at the united states department of agriculture are developing a new method of growing apple trees.

the scientists place apple plant shoot in 16-ounce jars with a growing medium. They cover the jars with 4-in. Preti dishes. Forty shoots grow in each jar. The shoots produce roots in about four weeks. After about two more months, the plantlets can survive outside the jars.

The scientists hope this new method will help orchard owners save money. The current method used to grow new trees costs orchard owner about $5 per tree. The new method could cost orchard owners less than $2 per tree.
