Growth and Biochemical Analysis of Tithonia rotundifolia Blake Flower

The invigorating beauty of flowers have always fascinated and enthralled people around the globe over the ages. Their beauty lies in their suppleness, their pleasant aroma and their diverse colors. From aesthetic as well as commercial consideration, flowers are important in India. Flower senescence is the extreme phase of developmental processes which leads to the death of flower and includes fading of blossoms, petal wilting, and shedding of flower parts. During flower bud opening, various events take place in a well defined sequence, representing all aspects of plant development, such as cell division, cellular differentiation, cell elongation or expansion and a wide spectrum of gene expression. So, the complexity of flower bud opening illustrate that various biological mechanisms are involved at different stages. The present study focuses on the estimation of growth and oxidizing and antioxidant enzymes during senescence of petals of Tithonia rotundifolia Blake cut flower.
