Analysis of morphological characters in soybean plants submitted to different levels of artificial shading

Morphological characters of soybean can be influenced by shading which are occasionally caused in plants. Thus, this study aimed to evaluate the effect different levels on epicotyl length, diameter and height The experiments were conducted a greenhouse. When plants reached V2 development stage, measurements taken length experiment I (conducted autumn); diameter, plant II (spring/summer) III (summer). Each randomized block design, subdivided plots, with four repetitions. plots composed subplots eight conventional cultivars. experimental unit consisted one grown 3 dm³ pot filled soil organic matter. three evaluated presented significant for interaction cultivar x sowing seasons. Epicotyl independent season, increased as level intensified. Both season epicotyl, general way, reducing increased. With increasing rate there was an increase height. Moreover, cultivars formed statistically distinct groups morphological evaluated.
