Studies On The Breeding Characteristics And The Influencing Factors Of Pollen Germination In Vitro Of Vaccinium Uliginosum

Vaccinium uliginosum?scientific name:Vaccinium uliginosum?,blueberry is deep blue are rich in anthocyanins,anthocyanins,with the promotion of erythrolabe re synthesis,delay brain aging and anti-inflammatory,enhance immunity,enhance heart function and anti-cancer and other physiological activity function.In this experiment,pollen viability of Vaccinium uliginosum,stigma receptivity,pollen ovule ratio,pollination mechanism,studied the breeding system and other aspects,the main contents and results are as follows:1.The results showed that the flowering order of vacciniumuliginosum inflorescence:in the upper part of a top upper part of inflorescence in the same reproductive branches in the upper part of the first open,about 2-3 days in the same inflorescence branches of the lower part of the reproductive branches began to open,the last is the upper part of the inflorescence branches open;inflorescence branch on the upper limbs began to blossom in flowering,flowering order from top to bottom;for the single flowers on the same inflorescence meet,the flowering order is outside Open,both sides in the middle of two flowers before the flowers open.2.The inflorescence flowering period is 7^-14 days,7-9 days to flower blooming in the morning,8:00^-10:00 open,7-9 days off.Anatomical observations.Anthers before flowering has been brought,part of the flowers are in blossom before the pollen fall to the flower.Of vacciniumuliginosum is measured on pollen viability and stigma receptivity.3.The orchid family farm vacciniumuliginosum material for breeding system of Vaccinium uliginosum were studied.The results showed that pollen ovule vacciniumuliginosum ratio is 33.3,hybrid index was 3,combined with bagging experiment results,that the breeding system of Vaccinium uliginosum as facultative selfing,selfing and pro,need to pollinators.
