Other claims from this paper (13)
- Observation In Spanish type varieties the first flower bud primordia formed on the first node of the primary lateral stem and differentiated when the second leaf appeared on the main stem.
- Observation In Spanish type varieties flower clusters formed in succession on the primary lateral stem but scarcely on the secondary one.
- Observation In Virginia type varieties the first flower bud primordia formed on the primary lateral stem at some distance from the base and differentiated when the fourth leaf appeared on the main stem.
- Observation In Virginia type varieties clusters formed at intervals on the primary lateral stem and abundantly on the secondary one.
- Observation Flowering followed about 10 days after pollen and ovule formation.
- Observation Of the several buds in a flower cluster, two develop more rapidly and bloom earlier than the rest.
- Observation Under favorable conditions the remaining buds of a flower cluster develop and bloom normally.
- Observation In Spanish type varieties 100 or more flower buds were formed about one month after planting.
- Observation In Virginia type varieties only about 30 buds were formed.
- Association Flower buds formed at an early stage of growth developed more vigorously than those formed at a later stage.
- Association Flower buds formed at an early stage of growth flowered and fruited more favorably than those formed at a later stage.
- Association In Virginia type varieties the number of flower buds was greater on the second lateral stem than on the first one.
- Association In Virginia type varieties the number of fruits was greater on the first lateral stem, as in Spanish type varieties.
