تاثیر پرایمینگ بذر با منابع و غلظت‌های مختلف پتاسیم بر وزن خشک اندامهای مختلف و درصد پتاسیم برگ پنبه در آزمایش گلدانی

Seed is growth and production foundation of plant. If seed has the better quality, Plant produce the more yield. Seed priming is a form of pre-treatment which can help to improve seed quality. In this study, cottonseed of Sahel variety was primed with potassium chloride, potassium nitrate and potassium sulphate in three concentrations 0.15, 0.30 and 0.45 mol/l and them were planted in pots containing 1.5 kg soil together control treatments consisting of distilled water primed and non-primed seeds. At the end of eighth weeks, wet and dry weights of total leaves and root + stem and leaf potassium concentration in dry matter were measured. Results showed that priming treatments significantly affect on leaf dry weight, total dry weight of roots + stem, rate of leaf dry weight to total dry weight of roots + stem and potassium percent in leaf dry weight. The mean comparison of data showed that chloride or nitrate potassium had considerably and sometimes superior to other treatments in production of the most traits of dry matter of various organs. Leaf potassium percent of the most priming treatments were significantly higher than control treatments as well as potassium nitrate 0.30 mol/l has the highest value.
