Effect of Bioregulators and day length on regulating juvenility and maturity (Phase change) in potato plants

نبذة عن كتاب Effect of Bioregulators and day length on regulating juvenility and maturity (Phase change) in potato plants

Potato (Solanum tuberosum L.) is one of the major crops of the world and ranks fourth after rice, wheat and corn in production Potatoes have been traditionally propagated asexually by using tubers, often called ”seed” tubers. Use of seed tubers for potato production has many advantages, including ease of planting, vigorous plant growth, uniform tubers and high tuber yields. However, with increased interest in production of potatoes in warm regions, use of seed tubers often becomes costly and has disadvantages. Some of the disadvantages of seed tubers in warm or developing regions of the world are; a lake of seed tuber certification programs, imported seed tubers are expensive, seed tuber often are contaminated with plant pathogens and other pests The present study included some trials to increase the ability of potato plants to form reproductive structures such as flowers, fruits and seeds using photoperiod and bioregulator treatments on two potato cultivars represented in two different genotypes. At the same time, to find out the link between vegetative growth and tuberization on one side and flowering on the other side.
