A Study on the Examining Methods of Speed for Seed Quality of Tree and the Computer Data Processing System for Visa

To solve the present shortcoming of slow and complicated coventional examination and data processing in testing of tree seed quality, 1581 seed samples of 139 tree species from 18 provinces in China were collected to carry out quick examination by photo of soft X-ray, dyeing by TTC method and moisture content by kett type electronic moisture instrument and conventional examination of seed quality. Several quick examination's rectificable models for germination percentage of nursery, germination percentage of laboratory and seed moisture content were established by applying various mathematic models. The computer data processing and visa system of seed quality's examination were successfully designed in APPLE-1 and IBM computer. The system can take in all original data of each index and examining method and at last print out examination certificate of tree seed quality according to differentiation of error rate, delimitation of grade and synthetical analysis of seed quality ia computer. The system have certain advantages of quick examination: simplicity, convenience, accuracy and complete function etc.
