Mycorrhizal fungi increase growth and reduce transplant injury in avocado
by John A. Menge , R. Michael Davis , Edward L.V. Johnson , George A. Zentmyer
pp6-7, doi#10.3733/ca.v032n04p6
Abstract
Avocados inoculated with beneficial mycorrhizal fungi have up to a 250 percent greater growth rate than non-mllcorrhizal avocados in sterilized soil Mycorrhizal avocados resist transplant shock because of better water absorption.Avocados inoculated with beneficial mycorrhizal fungi were shown to have up to a 250 percent greater growth rate than non-mycorrhizal avocados in sterilized soil. Transplant shock in avocado seedlings may be reduced by mycorrhizal fungi.

Testing ethephon-treated table grapes for berry firmness
by William L. Peacock , Fred L. Jensen , JoAnne Else
pp8, doi#10.3733/ca.v032n04p8
Abstract
Ethephon hastens color development and permits earlier harvest of table grapes, but it also reduces berry firmness. Eleven panelists compared untreated and variously treated grapes to detect textural changes.

Forage yields from ryegrass and ryegrass-cereal grain mixtures
by George F. Worker
pp17-18, doi#10.3733/ca.v032n04p17
Abstract
During two years of study no increase in pasture production could be obtained by adding barley to ryegrass. Instead, ryegrass yield was depressed the remainder of the growing season. Overall, ryegrass planted alone equalled or was better than the mixtures.

Stem pitting disease of cherries and other stone fruits
by Srecko M. Mircetich , William J. Moller , George Nyland
pp19-20, doi#10.3733/ca.v032n04p19
Abstract
Decline in cherry and other stone fruit orchards has been shown to be associated with a soil-borne virus disease known as Prunus stem pitting. Control is by careful selection and use of propagation material from healthy trees and planting in non-infested soil.
