On pollen technology

In the breeding work, sometimes you need to pollen save some time. While it has been known to lower the temperature of pollen save 0 ~ 15 ℃, air humidity slightly dry but also not too dry, dark conditions are most suitable.
       However, a variety of plant pollen longevity differences between the pollen itself is characterized by the decision, two decisions by the storage conditions. Generally, pollen cereals shorter life, especially self-pollinated plant pollen short lifespan, such as wheat anther dehiscence after 30min, fresh pollen from yellow to dark yellow that, at this time there are a lot of pollen loss of vitality. In many special conditions, the determination of the viability of pollen was very important, such as:
     1. Male flowering earlier than the pollen when the female parent to be stored for a short time in the field to collect pollen or hybrid;
  2. Selfing or outcrossing, in order to analyze the reasons for setting rate or not strong when;
  3. When the male sterile line in order to identify;
  4. Learn some hybridization techniques, such as the determination of pollen irritation and other effects, such as selective determination of fertilization.
      Therefore, according to the characteristics of a variety of plant pollen, take appropriate preservation methods. Determination of pollen viability of many, including germination test procedures more complex, higher equipment requirements, but also the longer it takes.
