Other claims from this paper (7)
- Intervention effect Mannitol-induced water stress, cool temperature and ABA raised proline in maize callus to 2.1–2.5 times control.
- Intervention effect Combined mannitol and ABA raised callus proline to about 4.5 times control.
- Association Proline accumulation increased with mannitol level.
- Observation ABA above 1.0 micromolar was needed to induce proline accumulation comparable to mannitol.
- Intervention effect Mannitol and ABA levels maximizing proline inhibited callus growth.
- Intervention effect Mannitol and ABA levels maximizing proline increased callus cold tolerance.
- Intervention effect Mannitol and ABA permitted cold storage of maize callus for 90 days, more than double typical survival.
