 ABSTRACT

Present study was carried out in forest nursery of Rani Lakshmi Bai Central Agricultural University Jhansi (U.P) in the year 2020-21. To study the effects of pre-sowing treatment on the seed germination and seedling vigour, fresh seeds are collected from Shidh seed sale corp Dehradun (UK) and Seed are clean and graded seeds were subjected to five different pre-sowing treatments for germination viz., Concentrated H2SO4 for 20 minutes followed by rinsing under running tap water (T1), Hot water treatment (100oC) for 10 second (T2), Cow dung treatment for 7 days (T3), Cow urine treatment for 24 hours (T4) and normal water treatment for 48 hours (T5).  The study revealed that seed pre-sowing treatments of the Sapindus mukorossi were significantly influenced the seed germination and seedling vigour. Germination percent Seeds subjected to different pre- sowing treatments ranged from 65 to 30 %. Acid treatment (T1) sowing the high germination per cent which is significantly at par with the other treatments. Germination energy was follow these trends T1> T2> T3> T4 > T5. Seedling length was depicted highest value (21.75 cm) in T1 (H2SO4 treatment for 20 minute) which is statistically at par with the other treatments while the minmum value was depicted in T5 (9.83cm). In case of collar daimeter, maximum value was recorded in T1 (4.80 mm) and lowest in T5 (2.51 mm). Whereas, mean root length of the seedlings was highest in T1 (16.58 cm) and lowest in T5 (9.31 cm). The root- shoot ratio also varied significantly among different pretreatments and the highest root- shoot ratio was recorded in T1 i.e. seeds soaked in H2So4 for 20 minute (0.26) and the least in T5 (0.15). With regards to seedling vigour index, the highest vigour index was recorded in T1 (16.72) scarifying the seeds in H2SO4 for 5 minutes and the lowest in T5 (4.37).

Keywords: Pre-sowing treatments, Germination energy, Germination per cent, Root shoot ratio seedling vigour.
