Title

Philip J. White; Martin R. Broadley; John P. Hammond; et al. The Journal of Horticultural Science and Biotechnology 2012. doi:10.1080/14620316.2012.11512842
Other claims from this paper (12)
- Association Environment influenced tuber zinc concentration.
- Association Genotype by environment interaction for tuber zinc concentration was not significant.
- Observation Mean tuber zinc concentration was 10.8 mg kg–1 dry matter.
- Observation The average ratio of lowest to highest varietal tuber zinc concentration was 1.76.
- Intervention effect Foliar zinc fertilization increased tuber zinc concentration.
- Intervention effect Foliar zinc below 1.08 g per plant did not significantly affect Maris Piper tuber yield.
- Association Tuber zinc concentration saturated near 30 mg Zn kg–1 DM at 1.08 g per plant foliar zinc.
- Intervention effect Foliar zinc at 2.16 g per plant increased shoot zinc concentration fortyfold versus controls.
- Intervention effect The same fertilization only doubled tuber zinc concentration.
- Mechanism Limited phloem mobility of zinc was proposed to restrict tuber zinc biofortification.
- Association Tuber zinc concentration was significantly positively related to tuber nitrogen concentration.
- Mechanism The zinc and nitrogen association supports their co-transport in phloem.
