Abstract
Asexual progeny of micropropagated (MP) plants of the cultivars ‘Earliglow’ and ‘Redchief’ had higher plant densities and yields than conventionally propagated (CP) plants in matted rows. MP plants partitioned 9–10% less of their total dry matter to leaf tissue. Micropropagated ‘Redchief’ increased its allocation to crowns and flower trusses; ‘Earliglow’ to fruit. Leaf area crown −1 was reduced in MP ‘Earliglow’ (49%) and ‘Redchief’ (55%), and yield crown −1 was lower (32%) in MP ‘Redchief’, but not ‘Earliglow’. Net photosynthetic rate (mg CO 2 dm −2 h −1 or μg CO 2g −1 dry wt. h −1 was greater in MP ‘Earliglow’ but not in ‘Redchief’. Stomatal conductance was higher in MP ‘Earliglow’, while mesophyll conductance was unchanged in both cultivars. MP plants of both cultivars had more stable PN rates across leaf densities than CP ones.
