| dc.description.abstract | Quantification Methods of Biometrical Plants Characters. Sutoro. Observation on characters consume much time and cost, especially in the research involving many unit of experiments. Therefore, quantification of plant characters method reducing time and cost necessary to be studied. Leaf area of corn at the flowering stage under optimum condition could be estimated by Y = 4.1844 (PxL)6 for plant with 8 leaves, Y = 5.0390 (PxL)5 for plant with 9 leaves, Y = 5.4416 (PxL)6 for plant with 10 leaves, Y = 6.3911 (PxL)7 for plant with 11 leaves, Y = 6.7134 (PxL)7 for plant with 12 leaves, Y = 6.7892 (PxL)e for plant with 13 leaves, Y = 7.1198 (PxL)9 for plant with 14 leaves, Y = 7.7282 (PxL)9 for plant with 15 leaves, (PxL), = leaf length x width at i-position (flag leaf = first position). Leaf area estimation on cassava by using Y = 0.8077 (PxLxn)08946 where PxLxn = product of maximum leaf length, width and number of lobe. Estimation of leaf area on sweet potato Y = 0.8 (PxL) for heart type's leaf, P = leaf length and L = maximum width, while star type's leaf by using Y = 0.47(PxL)11 P = leaf length and L = leaf width at the middle part. Leaf area estimation of soybean is Y = 2.1368 (PxL)09737 PxL = leaf length x maximum width of terminal leaf of trifoliate. Leaf area of mungbean is Y = 2.0235 (PxL)0'9 , PxL = leaf length x width of terminal leaf. Leaf area of peanut could be estimated by using leaf length (P) and maximum width (L) of left or right side on lower part of tetrafoliate by using formula Y = 4.1553 (PxL)094. Missing hills on soybean up to 15% under optimum condition doesn't effect to the grain yield. Corn plant which existing more than 5% of missing hills will effect to the grain yield. Image analysis could be used to quantified of morphological plant characters accurately. | en_US |
