چکیده مقاله :
Tuberose (Polianthes tuberosa L.) is an important commercial cut flower that has a short vase life. An experiment was carried out by using five different levels of humic acid (HA) (0, 25, 50, 75, and 100 mg L-1) and seven different levels of silver nano-particles (SNP) (0, 0.5, 1, 2, 3, 4 and 5 mg L-1) mixed with 1.5% sucrose on cut tuberosa cv. Single flower. The loss of fresh weight on third and sixth days in 25 mg L-1 HA+1.5% sucrose, 50 mg L-1 HA +1.5% sucrose and 75 mg L-1 HA+1.5% sucrose was less compared to other treatments. Also HA decreased lipid peroxidation. Silver nano-particles increased the water uptake, fresh weight, total protein, and declined lipid peroxidation compared to the control. Results showed that suitable levels of HA and SNP lead to better morphological and physiological properties and increase the vase life of cut Tuberose flower.
