    • Abstract


      The growth pattern, leaf morphology and flower development were studied inLycopersicon esculentum Mill. With the increase in concentration of morphactin the height of the plants and the length of the petiole reduced and leaflets of young primordial leaves gradually fused to form simple leaves. The length of the inflorescence axis gets reduced and leads to the formation of composite flowers due to a gradual condensation with the increase in the concentration of this growth regulator. The shedding of flowers, a common phenomenon in tomato plants during first flowering was checked and considerable increase in the number of fruits was observed by lower concentration of morphactin treatment.
