Abstract
Poor germination in Carica papaya L. was partly due to the absence of embryos in about 20% of the seeds. Final germination and the rate of seedling emergence were improved by seed separation with 1.097 g·em−3 sucrose solution and soaking with 1.0 M potassium nitrate (KNO3) or 600 ppm gibberellic acid (GA3). Final germination was 87.8% for the KNO3 treatment and 80.5% for GA3. Seedlings from KNO3 treatments were normal, whereas GA3 caused excessive elongation of stems.Keywords
