Effects of brassinolide on the physiological characteristics of maize (Zea Mays L.) Cultivars Under salt stress.
Effects of brassinolide on the physiological characteristics of maize under salt stress were investigated. Effect of exogenous application of brassinolide on the antioxidant system, endogenous hormone levels, sodium and potassium ion contents of the plants were measured in a salt-tolerant maize cultivar, Xianyu 335, and a salt-sensitive maize cultivar, Dongnong 253. Brassinolide induced better alleviation of physiological damage in different salt-sensitive maize cultivars under salt stress treatment. Exogenous administration of brassinolide was found to increase the antioxidant enzyme activity, modulate the endogenous hormone levels, and promote potassium and sodium excretion by the plants. The effect was more significant in salt-sensitive maize cultivars.

期刊介绍:
Bangladesh in situated on the north of Bay of Bengal. Climatically it is a humid subtropical country. Most of the land is deltaic plain of two great rivers, the Ganges and the Bhrammaputra and it tributaries. The country has rich diversity of plants. Main crops cultivated are Rice, Jute, Wheat, Maize, Sugarcane, Mustard and different kinds of Lentils. There are a good number of Public and Private Universities and Plant Research Establishments.
Bangladesh Journal of Botany is the official organ of the Bangladesh Botanical Society established in 1972. Since 1972 Bangladesh Journal of Botany is being published regularly. Two issues of the Journal are published, one in June and another in December.
Scientific papers (Full paper and short communication) on any field of Plant Sciences from anywhere in the World are considered for publication in Bangladesh Journal of Botany.
