Abstract or Summary
  • Experiments were conducted to determine: (1) effects of pretransplant stolon formation on performance of potato transplants in the field and greenhouse; (2) effects of parent plant nodal position on productivity of rooted nodal cuttings; and (3) relationships between photoperiod and stolon formation. The effects of early stolon formation on Russet Burbank transplants were studied using transplants with stolons present, stolons absent, and stolons removed. Field studies revealed no significant treatment effects on total yield, number of tubers per plant, weight per tuber or numbers of eyes per tuber. In greenhouse studies, the presence of stolons on transplants significantly increased total tuber yield, number of tubers per plant, weight per tuber, and eyes per tuber compared with plantlets with stolons absent at transplanting. Early stolon formation decreased transplant height but, as potato plants matured, treatment effects on vine length became negligible. Dry weight of mature top growth was not affected by early stolon formation. Transplants were taller, more tubers per plant were produced, tuber size was reduced, and total yield was lower in the first planting date than in the second planting date in the greenhouse study of experiment one. Lower light intensity during the nodal increase and crop growth may partially explain the significant differences in plant growth. Use of lower parent plant nodal sections for transplant production favored plant survival, early stolon formation, and high tuber yield. Central-to-lower parent plant nodal sections produced taller transplants than upper nodal sections. Nodal position did not significantly affect numbers of tubers per plant, tuber weight, or number of eyes per tuber. Short (8-hour) days in comparison to long (16-hour) days favored early stolon formation and increased stolon length on rooted nodal cuttings. Transplant height was reduced by short days.
