| Abstract | ||
| An experiment was carried out at the Lath-house Horticulture Dept. , faculty of Agriculture university of Kufa during growing season 2014 – 2015 to test the effect of foliar application of yeast extract and / or Salicylic acid on growth and flowering of Mathoilaincaana .L , Randomized Complete Block Design (R.C.B.D ) was adopted where yeast extract was at three levels ( 0 , 3 and 6 )g.l-1. and Salicylic acid at three concentrations ( 0 , 30 and 60 ) mg. l-1 with three replicates . Results show the superiority of spraying yeast extract at 6 g.l-1 significantly in vegetative , chemical , root and flowering characteristics Plant height, number of leaves, dry weight of vegetative part , leaf content of chlorophyll a , b and total , carbohydrates content , root length, dry weight of roots , number of inflorescence, length of inflorescence , number of floret , diameter of floret and inflorescence stem were increased. Salicylic acid at a concentration of 60 mg. l-1 with increased number of leaves, dry weight of vegetative part , leaf content of chlorophyll a , b and total , total carbohydrates , root length , inflorescence length , number and diameter of floret , while highest plant height was found when 30 mg. l-1 Salicylic acid was sprayed .Interaction of yeast extract at 60 g.l-1 + Salicylic acid at 60 mg. l-1 had the highest number of leaves , dry weight vegetative part , leaf content of carbohydrates , root length , dry weight of roots , number of inflorescence , inflorescence length , number of floret and floret diameter . However spraying yeast extract at 0 g.l-1 with 60 mg. l-1 .Salicylic acid increased shoot root ratio ( 5.64 ) as compared to control treatment ( 2.17 ) . | ||
