Abstract: 【Objective】 We aim to explore the relationship between pollen inclusion and pollen viability.【Method】 The pollen viability of Dangshan pear, which was stored at 4 degree centigrade conditions for for 0 days, 7 days, 27 days, 43 days and 65 days, was determined by means of in vitro pollen germination method. And the content of the protein fatty glucosinolins water in pollen was measured by near infrared spectrometer. 【Result】The results showed that: the protein content increased, the total fat content and glucosinolates were serrated, along with the pollen vitality decreased. The water content was increased with the increase of storage time and without desiccant. The studies have shown that pollen vitality are associated with fatty, glucosinolate, water content and protein. They correlation were 0.623, 0.813, -0.886, -0.807, respectively. 【Conclusion】Fat and glucosinolates are positively related to pollen vitality, and water content and protein are negatively correlated with pollen viability, and pollen respiration is reduced by drying in long term pollen storage. It has positive correlation that the pollen viability with fatty, glucosinolate. The pollen viability has negative correlations with water content, protein. Therefore, pollen are dehydrated to conserve them for depressed respiratory action.
