Figure 1: (a) Variables loading by factor analysis and varimax rotation with first two factors under inoculation condition and different water levels. X1: tiller numbers/plant, X2: spike length, X3: spikelets/spike, X4: spike weight/plant, X5: grain number/spike, X6: grain weight/spike, X7: 100-grain weight, X8: total chlorophyll content of flag leaf, X9: biological yield/plant, X10: root weight, X11: leaves area, and Y: grain yield. (b) Variables loading by factor analysis and varimax rotation with first two factors under noninoculation condition and different water levels. X1: tiller numbers/plant, X2: spike length, X3: spikelets/spike, X4: spike weight/plant, X5: grain number/spike, X6: grain weight/spike, X7: 100-grain weight, X8: total chlorophyll content of flag leaf, X9: biological yield/plant, X10: root weight, X11: leaves area, and Y: grain yield.
