Origin of Viruses

Abstract

IN recent times two abnormalities have arisen in the apple Lord Lambourne when this variety has been grafted on to certain other kinds: (1) where the branches and growth lack rigidity, so that the weight of even a few fruits pulls the branches almost vertically to the ground, (2) where the fruit only develops about a quarter of normal size. Thus when Lambourne has been grafted on to the variety Excelsior, Lambourne has developed non-rigid growth, and when grafted on to Redcoat Grieve it has developed the small-fruit abnormality. The same reactions have occurred in Lambourne when it has been grafted on to certain other kinds.
