Raspberry Rosaceae (Rosaceae) Rubus the genus (Rubus.L) small berry fruit , this summer fruit type raspberry of Phil Dodd \(Heritage) two varieties as test materials, after falling to the fruit overripe , sampling seven times after flowering , 7d, 14d , 21d, 28d , 30d, 32d , and 34d . By studying the fruit during the growth and development of weight, size , sugar , acid , vitamin C , soluble protein and fruit color development component of the dynamic changes in the ultra- microscopic structural changes , which reveals the growth pattern of the raspberry fruit growth and development for the future fruit regulation and the development of scientific cultivation and management measures to provide a theoretical basis . Test concluded as follows: (1) two varieties from fruit to flowers after 32d to mining maturity , regardless of the fruit fresh weight , vertical and horizontal diameter , volume showed an upward trend , \curve of the \21d ~ 30d after flowering has a significantly rapid growth phase . (2) during the fruit development of the two varieties of soluble solids , total soluble sugars , reducing sugars , soluble pectin content is gradually increasing ; total acid , starch , vitamin C, the original pectin content showed a decreasing trend for the first increase , respectively, after flowering, 28d , 14d , 28d , 21d reached the highest value ; soluble protein content is generally decreasing trend , but 32d after flowering increased , and Harry THz increase significantly ; cellulose content continued to decrease , flowers after 34d reached the minimum . (3 ) the total phenolic content of the two varieties during fruit development is to increase 14d after flowering reaches a maximum , and then decreases ; chlorophyll content were reduced after flowering 32d does not detect chlorophyll ; anthocyanin and carotenoid content continues to increase . ( 4 ) \gradually separating wall , vacuole expansion, the middle lamella bright - dark - the Ming regional structure dissolved signs , reduced organelle ; collapse of the cell walls of the mature stage , the cytoplasm liquefaction , membrane rupture, fruit softening .
