| dc.description.abstract | The present investigation was conducted at Vegetable Research Farm of Department of Vegetable Science, PAU, Ludhiana during January to March 2016 and 2017. The laboratory work was simultaneously conducted in Seed Technology Centre, Office of Director (Seeds), PAU, Ludhiana. The experiment was laid in split plot design keeping two environments (sowing in third week of January and third week of February) in main plot, three genotypes (Hara Madhu, Punjab Sunehri and MH-27) in sub-plot and eleven treatments along with control (hydration, GA3, KNO3, KH2PO4 and ethrel along with placing in wet gunny bags for 24 hours and 48 hours and hydration + FYM for 48 hours) in sub-sub plot. The physiological and biochemical parameters i.e. germination percentage, speed of germination, alpha amylase, total sugars, total protein and DNA content of seedling were recorded in laboratory. The physiological parameters like field emergence, speed of emergence, root length, seedling length, seedling dry weight, vigour index I, vigour index II and post emergence plant mortality were recorded from both the environments of field. The statistical analysis of data showed the superiority of the environment-2 over environmrnt-1 in all the field observations. The cultivar Hara Madhu was most responsive to seed priming treatments in both field and laboratory conditions. Seed priming treatments were significantly better over the control. Treating the seed with GA3 along with placing in wet gunny bags for 48 hours resulted in maximum germination (%), speed of germination, alpha amylase and total sugars content in laboratory. Similarly seeds treated with KH2PO4 along with placing in wet gunny bags for 48 hours gave maximum field emergence (%), speed of emergence, dry weight content, vigour index II in both the environments and DNA & protein content in laboratory while hydration along with placing in wet gunny bags for 48 hours resulted in maximum root length, seedling length and vigour index I. | en_US |
