Title

S. R. Miller Canadian Journal of Plant Science 1965. doi:10.4141/cjps65-102
Other claims from this paper (6)
- Intervention effect Leaf extracts from size-controlling rootstocks inhibited stratified apple seed growth.
- Association Rootstock vigor correlated negatively with apple seedling growth in leaf extracts.
- Association Rootstock vigor correlated negatively with wheat seedling growth in leaf extracts.
- Observation Two inhibitory zones were found in a watercress bioassay.
- Intervention effect The fraction at R f 0.4 to 0.6 affected IAA breakdown.
- Association More dwarfing apple rootstocks stimulated IAA oxidation.
