Enhancing Tuber Calcium Concentration May Reduce Incidence of Blackspot Bruise Injury in Potatoes

Enhancing Tuber Calcium Concentration May Reduce Incidence of Blackspot Bruise Injury in Potatoes

Our previous research has provided evidence that in-season calcium applications can increase tuber calcium and improve tuber quality with reduced internal defects. To determine if increasing the tuber calcium concentration also mitigates tuber bruise incidence, five commercially relevant potato (Solanum tuberosum L.) cultivars ( Russet Burbank , Atlantic , Snowden , Superior , and Dark Red Norl...

Enhancing the Natural Disease Resistance of Potatoes

In order to reduce pollution and strive for a cleaner environment, significant efforts are being made to develop alternatives to synthetic pesticides for the control of plant diseases. A promising alternative is to stimulate the natural resistance of plants. Recent advances in our understanding of the mechanisms of the expression of plant defense mechanisms when attacked by disease causing path...

Water-saving irrigation strategies affect tuber water relations and nitrogen content of potatoes

The dynamic and static deficit (DDI, SDI), partial root drying (DPRD, SPRD) and full (FI)irrigation strategies were applied in Agria and Ramos potato cultivars in a semi-arid area. FIreceived 100% of the potential evapotranspiration (ET); SDI and SPRD received 75% of ETduring the growth period; DDI and DPRD received 90% of ET in the first third, 75% of ET inthe second third and 50% of ET in the...

The effect of calcium supplementation in pregnancy on breast milk calcium concentration

Introduction: The relationship between calcium intake during lactation and breast milk calcium concentration has been studied by many investigators, but there is no conclusive evidence on the effect of supplementation during pregnancy on the breast milk content. The aim of this double blind, placebo controlled trial was to determine the effect of calcium supplementation during the third trimest...
