EFFECTS OF GIBBERELLIC ACID ON THE ANATOMY OF SOYBEANS
Jack M. Bostrack; Β. Esther Struckmeyer 1964
Other claims from this paper (15)
- Intervention effect Gibberellic acid treatment produced chlorosis of leaves and reduced leaflet size in soybean.
- Intervention effect Terminal leaflets of gibberellic acid-treated soybean had a slightly thinner lamina.
- Intervention effect Gibberellic acid-treated soybean leaflets had smaller cells in the palisade layer.
- Intervention effect Gibberellic acid-treated soybean leaflets had a greater amount of intercellular space.
- Intervention effect Gibberellic acid caused an early elongation of soybean internodes.
- Mechanism Increased cell elongation explains the early elongation of soybean internodes in gibberellic acid-treated plants.
- Intervention effect Reduction of stem diameter in gibberellic acid-treated soybean.
- Intervention effect Gibberellic acid produced more lignified xylem parenchyma in soybean stems.
- Intervention effect Gibberellic acid caused partial collapse of relatively thin-walled vessel elements and tracheids in soybean.
- Intervention effect The extension of axillary shoots of gibberellic acid-treated soybean was delayed temporarily.
- Intervention effect After a temporary delay, the axillary shoots of gibberellic acid-treated soybean quickly surpassed the growth of untreated shoots.
- Mechanism Cell elongation explains the rapid extension of axillary shoots of gibberellic acid-treated soybean.
- Intervention effect Anthesis was delayed in gibberellic acid-treated soybean grown in long days.
- Intervention effect The number of pods per plant was reduced in gibberellic acid-treated soybean grown in long days.
- Intervention effect The transition from the vegetative to the reproductive phase was delayed in gibberellic acid-treated soybean.
