Other claims from this paper (19)
- Observation Acacia stem xylem principal conducting cells were tracheids and vessels with simple perforation plates.
- Observation Acacia xylem vestures were branched and coralloid-like.
- Observation Most Acacia conduits were 1 to 5 cm long, comprising 89%.
- Observation Only about 2% of Acacia conduits were 15 to 16 cm long.
- Observation Mean Acacia conduit diameter was 77 ± 0.9 µm.
- Observation Twenty-nine percent of Acacia conduits had diameter 70 to 80 µm.
- Intervention effect S-carvone significantly extended Baeckea frutescens vase life.
- Intervention effect S-carvone significantly extended Chamelaucium uncinatum vase life.
- Observation S-carvone did not show antibacterial effects against Bacillus cereus.
- Intervention effect Regular recutting improved fresh weight, solution uptake and vase life in three native cut foliage species.
- Intervention effect Standard tap water improved Acacia relative fresh weight and solution uptake.
- Intervention effect Neither KCl nor CaCl2 significantly raised Acacia stem conductivity in experiment 1.
- Intervention effect In experiment 2, 100 mM KCl significantly increased conductivity in long Acacia stem segments over water.
- Intervention effect In experiment 2, 100 mM CaCl2 significantly increased conductivity in short Acacia stem segments over water.
- Association Acacia stem conductivity fell as segment length rose from 5 to 20 cm.
- Method / resource The microscopy method could not identify calcium peaks in Acacia xylem vessels.
- Intervention effect Ten mM KCl and CaCl2 yielded higher fresh weight, solution uptake and vase life than 0, 1 and 100 mM.
- Intervention effect Standard tap water significantly improved Acacia relative fresh weight and uptake rate against other vase solutions.
- Intervention effect Copper sulfate, calcium chloride, and copper sulfate plus potassium chloride significantly improved Acacia fresh weight and vase life.
