An experiment was conducted to investigate the effect of aluminium (Al) toxicity on the anatomical changes in the root, stem and leaf of chickpea (Cicer arietinum L.) plants grown in sand culture. Toxicity of Al reduced the length of primary root and the number of lateral roots of chickpea than that of the control. Aluminium decreased the size and number of vessels in the root of chickpea. Larger area of sclerenchyma cells was noticed in the stem of Al-stressed plant. Number of palisade parenchyma was reduced in the leaf of chickpea. Aluminium treatment caused closure of stomata. Increased number of trichomes in chickpea leaves was also reported due to aluminium. Dhaka Univ. J. Biol. Sci. 30(2): 187-196, 2021 (July)

The anatomical responses of chickpea (Cicer arietinum L.) roots to aging and severe water deficits and their capacity for subsequent initiation and growth of new lateral roots after rewatering are only partially known. This study was conducted to characterize the degeneration of epidermal and cortical cells of chickpea roots and the subsequent initiation and growth of new roots from bare steles, i.e., steles surrounded by an endodermis but lacking other parts of the cortex. Chickpea plants were grown in pots in a greenhouse under standard culture conditions (potting mix and daily watering) or drought treatments. For drought treatments, plants were grown in sand and exposed to repeated 10-d treatments of water deficits and rewatering. In standard culture conditions, older cortices collapsed and deteriorated but not simply as a function of chronological age. After one 10-d drought treatment, the epidermis and outer cortex of primary and some secondary and tertiary roots collapsed and after a subsequent rewatering treatment, the epidermis and cortex deteriorated and sloughed from steles. In both standard and drought conditions, bare steles were able to sustain growing root tips, indicating that the endodermis was effective in preserving stelar functions. In droughted plants, bare steles were able to initiate new lateral roots from the pericycle after rewatering, indicating that cortical tissue other than the endodermis was not necessary for secondary and tertiary chickpea roots to initiate new lateral roots. In a given root system exposed to the drought treatments, although the cortex collapsed on some roots, the cortices of other secondary roots did not collapse or deteriorate under similar severe conditions. The reason for cortical survival is unclear, but the response of these roots was similar to roots that have a suberized hypodermal layer which protects underlying cortical tissues from excessive drying. Key words: chickpea, Cicer arietinum L., drought, lateral roots, rewatering.

El garbanzo (Cicer arietinum L.) es una de las principales leguminosas de grano cultivadas en el mundo. México es de los diez principales productores a nivel mundial con una producción total de 171 mil toneladas de grano. Este cultivo presenta alto nivel de autogamia y de monotonía genética, lo que dificulta la diferenciación de genotipos élite. En este estudio preliminar se evaluó la variabilidad de 57 genotipos de diferentes áreas geográficas mediante caracteres morfológicos y marcadores moleculares tipo RAPD e ISSR. El análisis de correspondencia múltiple mostró que los mayores valores discriminantes fueron el color de la flor azul y semillas grandes y de forma redondeada, pero el agrupamiento respectivo no diferenció a las accesiones, incluyendo las especies silvestres; sin embargo, el análisis UPGMA logró una mejor separación. Los marcadores RAPD aun cuando generaron perfiles de ADN, no fueron informativos, mientras que los ISSR diferenciaron a las 57 accesiones de C. arietinum utilizadas y a la especie silvestre C. reticulatum, lo que los hace buenos candidatos para caracterizar este cultivo. Este estudio sirvió como base para desarrollar otro sistema de marcadores moleculares más eficiente en esta especie.
