Effect of colchicine on Kalanchoe daigremontiana Raym.-Hamet & H.Perrier (Crassulaceae) leaf morphology and stomates
The current study evaluated the effect of different concentrations and exposure times of colchicine on Kalanchoe daigremontiana leaf morphology and stomates. Initially, K. daigremontiana seedlings were harvested at concentrations of 0.025% and 0.1% (w/v) of colchine and at two exposure times (24 and...

| description | The current study evaluated the effect of different concentrations and exposure times of colchicine on Kalanchoe daigremontiana leaf morphology and stomates. Initially, K. daigremontiana seedlings were harvested at concentrations of 0.025% and 0.1% (w/v) of colchine and at two exposure times (24 and 48 hours). Subsequently, morphological studies, such as plant height (PH), leaf width (LW), number of leaves (NL), leaf length (LL), leaf thickness (LT) and leaf volume (LV), were done every 15 days for 16 weeks after sowing. Afterwards, the stomates were characterized, taking into account the width, length, stomatal index and number of chloroplasts per stomate. A significant increase in foliar and stomatal morphology was found in treatments with colchicine of 0.025% at 24 and 48 hours. This shows that the use of colchicine achieves greater growth in a short time and increased biomass in medicinal K. daigremontiana plants. |

El presente estudio evaluó el efecto de diferentes concentraciones y tiempo de exposición de colchicina, sobre la morfología foliar y los estomas de Kalanchoe daigremontiana. Inicialmente, se recolectaron y se sometieron las plántulas de K. daigremontiana a concentraciones de 0,025% y 0,1% (p/v) de colchicina y a dos tiempos de exposición (24 y 48 horas). Posteriormente, se realizaron estudios morfológicos como la altura de la planta (AP), anchura de la hoja (AH), número de hojas (NH), longitud foliar (LH), espesor de hoja (EH) y volumen foliar (VH) cada 15 días, durante 16 semanas después de la siembra. Luego, se caracterizaron los estomas, teniendo en cuenta el ancho, el largo, índice estomático y el número de cloroplasto por estoma. Se encontró un incremento significativo en la morfología foliar y estomática, en los tratamientos con colchicina de 0,025% a 24 y 48 horas. Lo que demuestra que el uso de la colchicina logra un mayor crecimiento en poco tiempo y aumento de la biomasa en la planta medicinal K. daigremontiana.
