Abstract:
Investigations were undertaken in the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalainagar, Tamil Nadu, India during 2015- 2017 to “Studies on effect of different seed treatments on dormancy breaking in Aonla (<em>Phyllanthus embolic</em> L)”. The seeds were treated with T<sub>1</sub> - Tap water for 24 hrs, T<sub>2</sub> - Hot water 25<sup>0</sup>C for 10 seconds, T<sub>3</sub> -Hot water 50<sup>0</sup>C for 10 seconds, T<sub>4</sub> - GA<sub>3</sub> 250 ppm for 24 hrs, T<sub>5</sub> – GA <sub>3</sub> 500 ppm for 24 hrs, T<sub>6</sub> - KNO<sub>3</sub> 1 per cent for 24 hrs, T<sub>7</sub> - KNO<sub>3</sub> 2 per cent for 24 hrs, T<sub>8</sub> - H<sub>2</sub>SO<sub>4</sub> 0.25 per cent for 3 minutes, T<sub>9</sub> - H<sub>2</sub>SO<sub>4</sub> 0.50 per cent for 3 minutes, T<sub>10</sub> - Stratification at 5<sup>0</sup>C for 10 days, T<sub>11</sub> - Stratification at 10<sup>0</sup>C for 10 days and T<sub>12</sub> -Control (untreated). There were twelve treatments replicated thrice in completely randomized block design. Among the different treatments, 2 per cent KNO<sub>3</sub> for 24 hours significantly increased the seed germination percentage, highest root length and highest dry matter content followed by GA<sub>3 </sub>500 ppm for 24 hours as compare to other treatments. Shoot length, days taken for 50 per cent germination, days taken for graf table thickness and Vigor Index was highest in seed treatment with GA<sub>3 </sub>500 ppm for 24 hours.
