Effect of various treatments on seeds germination in Indian jujube (Ziziphus mauritiana Lamk)

This experiment was carried out to study the effect of various treatments on seed germination in ber. The treatments consisted of T1 (control seed sown fresh, T2 (H2SO4 for 8 minutes),), T3 (Seed kernel sown), T4 (18% salt solution dip for 24 hrs), T5 (18% salt solution dip treatment for 48 hours), T6 (cracking of seed coat with hammer), T7 (18% salt solution dip treatment+36hrs water dip treatment), T8 (One year old seed sown). The results of this experiment show that among various treatments days taken for seeds germination ranged from 9.60-18.40 and 9.2-19.6 days during 2005 and 2006 respectively. There was early seed germination in T3 treatment followed by the T8. In T3 treatment germination were started 9.6 and 9.2 days after sowing seeds during 2005 and 2006 respectively. The duration of seed germination among various treatments ranged between 10 to 32.3 days. Minimum numbers of the days taken for completion of germination of seeds were recorded in T3 treatment followed by T8. In this treatment seed germination was completed with in 10 days after seed germination was started. The   seed germination ranged between 18.6-68.6 and 17.0 -71.6 percent during 2005 and 2006 among various treatments respectively and maximum percent seed germination was recorded in T8,  in which germination was 68.6 and 71.6 per cent during 2005 -06 respectively. The mean maximum seedling height was recorded in T8 treatment and this was followed by the T3 treatment. The results are very encouraging that within same season there was 70.52 per cent seedling become bud able in T8 treatment. Maximum height of budded plant was recorded in T8 when seeds were sown after one-year storage this was followed by T4 and minimum (61.30cm) was recorded in T2.
