Improving Growth Performance of <i>Jatropha curcas</i> by Inducing Polyploidy through Colchicine Treatment

Abstract

This study was planned to assess genetic variation in Jatropha curcas as affected by colchichine treatments. During the experiment, seeds of Jatropha curcas were collected from mature and healthy Jatropha plants and were soaked in different concentrations of colchicines. The second treatment was that of time of soaking (seeds were soaked in different concentrations for different time durations). The results clearly revealed that by increasing the concentration of colchicine treatment, parameters like stomatal density, and size of the guard cells were reduced.

Cytogenetics and Consequences of Polyploidization on Different Biotic-Abiotic Stress Tolerance and the Potential Mechanisms Involved

“…Fruit size and fruits number, along with other fruit characteristics such as fruit weight, fruit peel, flesh weight and seed number are affected by the increase of ploidy number [ 130 , 138 , 139 , 140 , 141 , 142 , 143 , 144 ]. Due to variations in cell size and chromosome size ( Figure 5 ), polyploidy changes the characters of the leaf [ 145 , 146 , 147 , 148 , 149 , 150 , 151 , 152 , 153 ]. Stomata number, density, size, and area are the important traits of leaves that are affected by the change of ploidy number [ 154 , 155 ], and this effect ( Figure 5 ) has been observed in citrus [ 120 ].…”
