A New very late ripening flat Peach Variety 'Rui '21'
Flat peach is a variety of peach and is a special resource in China. The Institute of Forestry Fruit trees of Beijing Academy of Agricultural and Forestry Sciences has carried out the flat peach breeding program since the end of 1970s, and many varieties have been widely popularized in production, but the extremely late-maturing varieties with fruit development period of more than 160 days are still rare. 'Ruifei 21'(see Fengsan Sancai photo) is a new very late maturing flat peach variety obtained by crossing 'fantasy' × 'Ruili No. 4' (1996). It was approved by Beijing crop Variety approval Committee in 2006. Variety characteristics

Storage characteristics and fresh-keeping Technology of Pear
Pear is one of the three major fruits in China, and its output ranks first among the three major fruits. The amount of deep processing is limited and the decay rate is high. In order to prolong the market supply, combined with its variety characteristics to do a good job of storage and preservation, reduce urban biological waste, and provide a guarantee for the income of the pear industry. Biological characteristics Pear is composed of fruit, core and seed. The growth process of pear fruit is an S-shaped growth curve, which is mainly cell division and embryo growth in the early stage, the volume increases slowly, and the fruit grows rapidly in the later stage, which is about 40-50 days before harvest.
