THE STUDIES ON THE RELATIONSHIP BETWEEN THE OUTPUT OF AUBERGINE AND FRUIT VEGETABIE AT EARLIER STAGE AND THE QUALITIES OF THEIR SEEDLINGS

Through the analyses drawn from the meaterials investigated on the relationships between the properties of 20 kinds of aubergine and fruit vegetable seedbng in various numbers, the derivative items and their output at earlier stage when the seedling were trasplanted.We can draw such an equation:y = a +bLnG. In the equation, y refers to the output of transplantable vegetable at earlier stage while G refers to the avera-gely daily absolate growing ( G refers to the proportion of seedling's weight to the numbers of days of seedling) . Since nearly 80% of the proportion of seedling weight consists of the proportion of the stem-leaf's weight, the proportion of the stem-leaf's weight to the numbers of days of seedling can be considered as G replacing the proportion of seedling weight to the numbers of days of seedling. When LnG is expressed with x,the equation y = a + bLnG will change into lineal equation y = a + bx.In measure of the qualities of aubergine and fruit vegetable seedling, LnG stands for the index of fine seedling.
