“…Vieira et al (2016) suggested that synthesis of citral, geraniol and other compounds prevailed in diploids, while non-oxygenated monoterpenes were the major ones in polyploids of Citrus limonia. Hannweg et al (2016) also identified changes in major chemical components of essential oils due to the polyploidy induction in Tetradenia riparia (Hochst.) Codd (Lamiaceae), a close related family of Verbenaceae.…”

Polyploidy is widely recognized as a major evolutionary force in plants and has been reported in the genus Lippia (Verbenaceae). Lippia alba, the most studied species, has been documented as a polyploid complex involving at least four ploidal levels. L. alba presents remarkable chemical and genetic variation and represents a model for understanding genome organization. Although the economic and medicinal importance of the species has been widely described, no established polyploid induction protocol has been reported so far. Here, we describe the production of synthetic polyploid plants of L. alba using colchicine. The ploidal levels were estimated by flow cytometry and chromosome counting. In addition, FISH and molecular markers approaches were used to confirm the stability of the synthetic polyploids. The major component of the essential oils was estimated by GCMS to compare with the natural individuals. Tetraploids and triploids were produced providing new opportunities for investigating medicinal, pharmacological, and economic applications as well as addressing intrinsic questions involved in the polyploidization process in tropical plants.

“…polimerización de la tubulina durante la formación del huso mitótico, lo que causa el bloqueo de la metafase y dispersión de los cromosomas en la célula (Planchais et al, 2000). La ventaja más importante de la poliploidía, es que las plantas suelen tener mejor rendimiento y características morfológicas, como la altura y el tamaño de los órganos vegetales (Hannweg et al, 2016), y el aumento de la biomasa en general (Urwin, 2014).…”

SegúnHannweg et al (2016), la ventaja más importante de la poliploidía inducida es que las plantas obtenidas suelen tener mejor rendimiento y características morfológicas tales como altura, mayor tamaño de hojas, rizoma o raíz. Asimismo, incrementa la biomasa, la capacidad fotosintética, el tamaño de los frutos y semillas(Urwin, 2014).…”

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.

“…Relação que continua em tribos africanas como, Abayanda e Bakiga devido à falta de acesso a produtos sintéticos (HAMILL et al, 2000). A T. riparia também conhecida como falsa mirra, incenso, lemonete, pluma-de-névoa e lavândula, natural da África do Sul é um arbusto com folhas verde-acinzentadas, de clima subtropical/temperado com sua altura variando de 1,5 a 2,0 metros, flores brancas na maioria dos casos, porém a ocorrência de flores lilás ou rosa pode acontecer (GAZIM et al, 2010;HANNWEG et al, 2016). É amplamente usado de forma medicinal pela população ao longo do tempo para tratar uma grande variedade de doenças, entre elas: dores de cabeça, febres, infecções, malária, angina, doença tropical de pele, tosse, úlcera, abscessos dentários, esterilidade feminina, doenças renais até mesmo como antiparasitário (PUYVELDE et al, 2018…”

Since ancient times the medicinal plants helped the society's development in order to reach the present resources. The Lamiaceae family is one of the main, containing a large number of species with medicinal potential and Tetradenia riparia is among them. The harvest of T. riparia leaves occurred in the morning at the Universidade Paranaense's medicinal garden, in Umuarama-PR. The extraction of the essential oil (EO) was done by hydrodistillation, the yield was calculated based on the mass of fresh leaves and EO extracted, obtaining 0.4%. Chemical characterization was performed by gas chromatography attached to a mass spectrometer and found 16 components and the major components identified were: Stigmasta-5,22-dien-3-ol (34.80%); Shyobunol (22.50%); α-Terpinene (15.79%) and β-Cembrenediol (11.05%).
