Batsch) rootstock Flordaguard” were carried out at the New Orchard of the Department of Fruit Science Punjab Agricultural University, Ludhiana during 2010-2011. Fruits of peach rootstock ‘Flordaguard’ were harvested in the 2nd week of July and the seeds were extracted, washed, dried and then stored in the gunny bags for stratification. The seeds were sown on three dates at 10 days interval (15th December, 25th December and 5th January) after stratification (which was considered as control), scarification (mechanical rupturing of the seed coat) and after soaking in GA3 (100 & 200 ppm), thiourea (1% & 2 %) and Kinetin (100 & 200 mg/lt) for 24 hours before sowing. The germination was started and completed earlier and the seed germination was found to be maximum when the seeds were sown after scarification. The vegetative parameters in terms of height, girth and number of leaves of the seedlings was also significantly higher under this treatment. The root growth and survival percentage of the seedling at the end of the experiment was found to be maximum when the seeds were sown after scarification on 25th December. All the growth regulators were not found to be effective for improving seed germination in peach rootstock ‘Flordaguard’.ennullThesis
