Abstract
Three-year-old highbush blueberry plants ‘Bluecrop’ and halfhigh blueberry ‘St.
Cloud’ grown under moss, sawdust or bark mulch and as an un-mulched control were evaluated for plant growth and physiology.
Results showed that the growth under mulching treatment of ‘Bluecrop’ were better than that under the control treatment. In ‘Bluecrop’, plant height and width, shoot length, dry weight of 100 leaves and dry weight of roots were in the order of moss> bark> sawdust> control.
In ‘St.
Cloud’, there was no significant difference in growth among different mulching treatments.
The photosynthetic rate and respiration increased in mulched plants compared to the control and was in the order of moss> bark> sawdust.
Membrane permeability and total sugar decreased with the mulching treatment.
Mulching is an important method for blueberry cultivation and moss mulching was found to be the best.
