Root Pruning Effects on Growth and Yield of Red Raspberry

Rebecca L. Darnell; Horacio E. Alvarado-Raya; Jeffrey G. Williamson HortScience 2008. doi:10.21273/hortsci.43.3.681

Other claims from this paper (12)

Observation Dry weights of all organs except floricane stems rose across the growing season.
Intervention effect Root pruning decreased root dry weight.
Intervention effect Root pruning decreased floricane lateral dry weight.
Intervention effect Root pruning decreased total fruit dry weight.
Intervention effect Root-pruned raspberry had fewer fruits per cane than controls.
Observation Root carbohydrate concentration fell significantly between pruning and budbreak in both pruned and control plants.
Intervention effect Root-pruned raspberry had lower root carbohydrate concentration than controls.
Intervention effect Root-pruned raspberry had lower root carbohydrate content than controls.
Mechanism Lower root carbohydrates during budbreak apparently limited flower bud formation and reduced yield.
Mechanism The authors conclude loss of root carbohydrates during nursery removal limits annual-system raspberry yield.
Recommendation The authors recommend practices that raise raspberry yield per plant by ameliorating root loss.
Recommendation The authors recommend practices that raise raspberry yield per hectare by increasing planting density.

Observation Melons produced 275 fully developed seeds per fruit in autumn.
Observation Melons produced only 57 fully developed seeds per fruit in winter.
Observation Mean melon seed weight was higher in autumn.
Observation Melon seed yield per plant was significantly higher in autumn.
Intervention effect Pollen load did not significantly affect germinability of autumn melon seeds.
Intervention effect Pollen load did not significantly affect germinability of winter squash seeds.
Observation Melon seeds from passive pollination had lower germinability.
Mechanism The authors suggest that low seed number from passive pollination may favor slow and distributed germination.
