Other claims from this paper (19)
- Intervention effect Growth chamber stock plants yielded shoot tips with less endogenous contamination than greenhouse stock plants.
- Intervention effect Bleach concentrations of 20%, 40%, and 60% produced no differences in surface contamination rates.
- Intervention effect No explant damage was observed at any tested bleach concentration.
- Intervention effect Shoot tip and nodal explants had no differences in growth and multiplication rate.
- Intervention effect Agar, agargellan, and gellan gum did not differ at standard rates.
- Intervention effect Murashige and Skoog basal medium was superior to Lloyd and McCown medium.
- Intervention effect Linsmaier and Skoog basal medium was superior to Lloyd and McCown medium.
- Intervention effect Driver and Kuniyuki Walnut medium was superior to Lloyd and McCown medium.
- Intervention effect Tested medium pH levels did not differ in final fresh weight, shoot length, or quality ratings.
- Intervention effect Sucrose at 1.5% and 3.0% produced greater fresh weights, shoot lengths, and quality ratings.
- Intervention effect Temperatures of 28 and 26 °C produced greater fresh weights, shoot lengths, node numbers, and quality ratings than cooler temperatures.
- Intervention effect The 5.0-μM TDZ treatment produced greater fresh weight and lateral node number.
- Intervention effect The 5.0-μM TDZ treatment produced the shortest shoot lengths and lowest quality ratings.
- Intervention effect 2iP at 1.0 and 5.0 μM gave the greatest quality ratings.
- Intervention effect BA at 1.0 μM gave the greatest quality ratings.
- Recommendation The 5.0-μM 2iP level was judged the best stage II multiplication treatment because of high ratings, fresh weight, shoot length, and node number.
- Intervention effect The three named auxin treatments gave the greatest shoot and root fresh weights and node numbers.
- Intervention effect The 2.5-μM IBA treatment had a higher overall rating.
- Intervention effect Dome acclimation produced greater shoot height, shoot weight, and overall ratings than mist acclimation.
