Impact of different seed treatments on germination of chironji (Buchanania lanzan Spreng.)

An experiment was conducted to study the effect of different seed treatments on germination and seedling growth of chironji (Buchanania lanzan Spreng.) carried out under propagation chamber at College Farm, College of Horticulture, Jagudan during October, 2022 to March, 2023 and laid out by Completely Randomized Design withthree repetition and fifteen treatments viz.,T1: Absolute control; T2: Water soaking for 24 hrs.; T3: Hot water treatment (99±1 °C for 10 second); T4: Hot water treatment (99±1 °C for 30 second); T5: Mechanical scarification (break seed coat by hammering); T6: H2SO4 @ 2.5% for 10 minute; T7: H2SO4 @ 5% for 10 minute; T8: GA3 @ 200 ppm for 24 hrs.; T9: GA3 @ 400 ppm for 24 hrs.; T10: Cow urine @ 10% for 24 hrs.; T11: Cow urine @ 20% for 24 hrs.; T12: Cow dung slurry @ 10% for 24 hrs.; T13: Cow dung slurry @ 20% for 24 hrs.; T14: Beejamrut @ 5% for 24 hrs.;T15: Beejamrut @ 10% for 24 hours. Among seed soaking treatments, T5 [Mechanical scarification (break seed coat by hammering)] significantly recorded minimum number of days taken for germination (24.53) and maximum germination percentage (63.67).
