Effect of Presowing Treatments on Germination and Vigour in The Seeds of Bambusa Bambos

The pre-sowing invigouration treatments have been proven to be beneficial in improving vigour and viability of seeds. The present study was conducted to explore the role (if any) of invigouration treatments to improve the germination, seedling emergence, early seedling establishment and viability in bamboo seeds. The bamboo seeds were treated with various invigourating solutions (e.g. salicylic acid, ascorbic acid, KNO3, GA3 PEG etc), whereas untreated seeds were taken as control. The most effective concentrations in seed hardening treatments with different chemicals were found to be GA3 (50ppm), resorcinol (10%), salicylic acid (10%), KH2PO4 (5%), CaCl2 (5%), urea (10%) and ascorbic acid (10%). The most significant fortification treatment with different chemicals were found to be ascorbic acid (5%), GA3 (50ppm) and KH2PO4 (5%). Whereas in case of osmopriming, the most significant treatment was found to be KCl (10%), KNO3 (5%), CaCl2 (10%) and PEG-6000 (5%) with which seeds show maximum vigour and viability of maximum even up to 24-months.
