e2“During rooting, photosynthesis in the cuttings is very low and has almost no effect on the carbohydrate content, so that starch appears to be the major source of carbohydrates”

Other claims from this paper (12)
- Intervention effect Sucrose applied with IBA improved rooting percentage, adventitious root number and root length of olive cuttings.
- Intervention effect IBA improved rooting of easy-to-root and moderate-rooting olive cultivars.
- Intervention effect IBA did not stimulate root formation in hard-to-root olive cultivars.
- Observation Photosynthesis in rooting olive cuttings was very low.
- Intervention effect IBA increased the rate of amyloplast disappearance in rooting olive cuttings.
- Observation Amyloplast levels decline during rooting of olive cuttings.
- Observation A significant percentage of rooted olive cuttings collapse during hardening when no starch pool is available.
- Mechanism Photosynthesis of fully-expanded leaves can supply the carbohydrates needed by rooted olive plants.
- Association Carbohydrate supply may not be enough to keep rooted olive plants alive when top growth is reduced in IBA-treated cuttings.
- Mechanism Carbohydrates have an important role in rooting and improve the stimulatory effect of IBA.
- Mechanism During adventitious root formation the endogenous carbohydrate pool is the main source of carbohydrates.
- Mechanism In young rooted olive plants the main source of carbohydrates comes directly from photosynthesis.
