| description | Horticulture is a dynamically evolving and an ever-changing sector which needs new ideas, plant materials, and cultivating methods to produce more. Involving different mutants in breeding lines may lead to new opportunities to create new cultivating methods. <i>pcx</i> (procumbent plant) and <i>tti</i> (tortuosa internodi) <i>Capsicum annuum</i> mutant plants, which present abnormal stem growth, were investigated in various in vitro experiments. The <i>pcx</i> breeding line presents highly diverse hypocotyl growth even in the early phenophase, such as normally growing plants and the ‘laying’ habit. On the other hand, <i>tti</i> plants only present their elongated slender stem trait in a more mature phase. In our experiment of reorientation, we used one-sided illumination, where each of the phenotypes sensed and reacted to light, and only the <i>pcx</i> plants exhibited a negative gravitropic response. It was also the result that the <i>tti</i> plants sensed gravity, but the weak structure of the hypocotyls made them incapable of following its direction. Since the <i>pcx</i> plants were the only ones with an ‘antigravitropic’ growth, we used them to evaluate the time course they needed to adapt and follow the gravity vector after reorientation. The <i>pcx</i> plants sensing gravity adapted similarly to controls and started bending after 120 min, but those which presented as ‘anti-gravitropic’ did not respond even after 420 min. |
