The nutritional attributes of sesame, Sesamum indicum, vary substantially and are primarily influenced by the plant’s genetic makeup. This investigation accessed the biochemical composition of sesame mutants from two generations. Seeds of eleven M3 lines were planted in a Randomized Complete Block Design (RCBD) to raise M4 lines, which were advanced to M5 generation. The seeds were harvested at maturity, and their biochemical compositions were quantitatively determined following standard procedures. Results revealed significant differences (p 0.05) was observed in ash content of M4 and M5 muta

Based on the existing research on sound symbolism and crossmodal correspondence, this study proposed an extended research on cross-modal correspondence between various sound attributes and color properties in a group of non-synesthetes. In Experiment 1, we assessed the associations between each property of sounds and colors. Twenty sounds with five auditory properties (pitch, roughness, sharpness, tempo and discontinuity), each varied in four levels, were used as the sound stimuli. Forty-nine colors with different hues, saturation and brightness were used to match to those sounds. Result revea
