Abstract:
Cadmium is a significant limiting factor in the production of oilseed crop in industrial
area. A pot experiment was conducted in the Sher-e-Bangla Agricultural University
from November 2019 to February 2020 to observe the performances of three
Brassica species (B. oleracea, B. campestris, and B. juncea) seeds exposed to two
levels of cadmium stress; mild and severe stress (2mM and 4mM CdCl
) in a
completely randomized design with three replications. The results revealed that
cadmium had a significant negative impact on plant height, leaf number, siliqua
length, seed per siliqua, SPAD value and seed weight of all tested Brassica species
resulting in yield loss. Mild cadmium stress decreased yield of B. oleraceae (BARI
Sharisha 17), B. campestris (BARI Sharisha 14) and B. juncea (BARI Sharisha 16) by
9.52%, 17.53% and 13.52%, respectively. Furthermore, severe cadmim stress
decreased yield of B. oleraceae, B. campestris and B. juncea by 46.26%, 39.61% and
31.88%, respectively. So, under mild stress, BARI Sarisha 17 (B. oleraceae) is the
best variety, while under severe stress conditions, BARI Sarisha 16 (B. juncea) is the
best variety.
