Crop: Guava
Problem :dormancy –due to hard seed coat hence no germination or less germination in Untreated seeds
Treatment-Scarification with HCL 35% for 3 minutes results in 95%higher germination
untreated treated
Crop: Rose
Problem :dormancy –due to hard seed coat and immature embryo hence no germination in Untreated seeds
Treatment-scarification with HCL 75% for 15 minutes and stratification for 3 months at 100 C results in 40% higher germination
Crop: Carrot
Problem : Poor storer – Quick loss of a viability at ambient condition - 60% after one year of storage at ambient conditions
Treatment : Seed priming with KH2PO4,KNO3,K2SO4@0.01 M for 24 hrs increased germination by 18-20%
60 % germination 78% germination
Crop: Lawsonia innermis
Problem : low germination at
Constant temperature and in dark conditions
Treatment: alternate temperature and exposure to light gives 100 % germination
