Title

RD Naidu; NB Jones Southern Hemisphere Forestry Journal 2007. doi:10.2989/shfj.2007.69.1.3.165
Other claims from this paper (12)
- Association Larger Eucalyptus seeds germinated better; the smallest germinated poorly.
- Association Grade 4 Eucalyptus grandis had lower nursery survival.
- Association Grade 4 did not lower E. smithii nursery survival.
- Association Grade 4 seeds produced the shortest seedlings.
- Mechanism Slower germination in Grade 4 seed trays was attributed as the reason for short seedlings.
- Association Grade 4 seeds produced seedlings with larger root collar diameters.
- Mechanism More empty spaces from poor germination were attributed as the cause of larger root collar diameters.
- Observation Field survival was good regardless of species or seed grade.
- Association At 12 months, seed orchard source significantly affected all E. grandis response variates.
- Observation Seed size effects were transitory and absent one year after field planting.
- Recommendation Smaller seeds can be used commercially if sown with similar-sized seeds.
- Association Seed orchard source was important for predicting field growth.
