Method for prolonging tobacco pollen storage time by utilizing tobacco seed oil

The invention provides a method for prolonging tobacco pollen storage time by utilizing tobacco seed oil, which comprises the following steps: squeezing out tobacco seed oil by adopting a physical squeezing method; mixing fresh tobacco pollen and dry allochroic silicagel with the particle size of 1-2mm according to the mass ratio of 10:1 in a storage container; and weighing tobacco seed oil according to the proportion that 1ml of tobacco seed oil is added into 1g of pure tobacco pollen, adding the tobacco seed oil into the mixture of the tobacco pollen and the allochroic silicagel, sealing the storage container, repeatedly vibrating for dispersing the air between the tobacco pollen and the allochroic silicagel, and putting at low-temperature environment for storing. Experiments prove that the tobacco seed oil can reduce the breathing rate of the pollen, reduce the deterioration velocity of the pollen and greatly prolong the storage time of the pollen; by adding the allochroic silicagel with a small particle size, the water of the pollen can be lost slowly, and the flexibility of the pollen wall can be enhanced by the tobacco seed oil; the damage to the tobacco pollen caused by desiccation and low temperature is further reduced; and the tobacco seed oil can not influence the biological characters of the tobacco pollen.
