POSTHARVEST STORAGE OF BARE-ROOT HARDY PERENNIALS: THE RELATION OF WATER LOSS TO STORAGE SURVIVAL |
| Authors: | A.C. Cameron, M. Maqbool |
| Abstract:
The relationship between percent water loss and storage survival of bare-root hardy perennials was investigated. Freshly harvested bare-root perennials were packed in burlap, cardboard, cellophane, perforated polyethylene or polyethylene and were stored at -2°C for four or six months. Weight loss and regrowth quality were measured for all plant material following storage. Water loss varied from nearly 0% to 60% based on the difference between initial and final fresh weights. The results revealed a significant inverse linear relationship between water loss and regrowth quality (r2 > 0.90 in all cases). Models were developed which predict regrowth quality based on measured transpiration rates and these results. | |
