Research on correction coefficient from leaf area for different soybean leaf forms
Three methods of leaf area scanning, photocopying weighing and photoshop image processing were used for measuring correction coefficients of leaf area of soybean's circular, ovate and lance shaped trifoliolate leaves. The result showed that, the correction coefficients of leaf area increased by ovate, lance shaped and circular soybean leaves; the correction coefficients of leaf area form the left and right leaves of soybean's trifoliolate leaves were very close, and they were both higher than the middle leaf; the correction coefficients of leaf area got by leaf area scanning and photoshop image processing were very anastomosis, however, data got by photocopying weighing was more erroneous. The correction coefficients of leaf area from ovate, lance shaped and circular soybean leaves were 0. 67, 0. 68, and 0. 70. The middle leaves were considered to be the most representative, and the data got by leaf area scanning was suggested to be used.
