Effect of chromium on activities of hydrolytic enzymes in germinating pea seeds

Effect of Heavy Metals on Biochemical Profile of Azolla filiculoides

“…The present findings gain support from the work of Bhushan and Gupta (2008) who also reported the decreased amylolytic activity in Oat seed germination in presence of heavy metal Lead. A similar trend in amylolytic activity was reported during seed germination in presence of Lead by Thimmaiah, 1989;Mukherji and Mukherji, 1990;Deep, 2002;Bansal, 2001;Dua and Sawhney, 1991;Bindu and Bera, 2002. In control plants of A. filiculoides the α amylase activity was high i. e. the plants produced 42.75mg of maltose per hour ten days after growth in hydroponic condition. The α amylase activity in heavy metal treated plants decreased with increasing concentration of heavy metals.…”

Determination of the levels of some heavy metals in African pear (<i>dacryodes edulis</i>) marketed in Lagos metropolis, Nigeria

“…This type of profile in reducing sugars may be ascribed to disruption in the supply of sucrose from endosperm either due to depressed synthesis or export. Similar increase in reducing sugar content in cotyledons of germinating pea seeds has been observed by Dua and Sawhney (1991) and Bansal (2001). Total amlyolytic activity was enhanced during 12 days of germination in endosperm of control as well as in the seeds germinated in presence of lead (Table 4).…”

“…25, 50, 100, 200, 300 and 400 ppm) compared to the activity observed in control. Other authors also reported the similar trend in amylolytic activity during germination as affected by various heavy metals in variety of seeds including wheat (Thimmaiah, 1989), rice (Mukherji and Mukherji, 1990), pea (Deep, 2002;Bansal, 2001;Dua and Sawhney, 1991). The increase in activities with the passage of time may be due to de novo synthesis and mild inhibition on 12 th day due to acclimatization of activities in response to lead.…”

Screening Indian Mustard Genotypes for Phytoremediating Arsenic‐Contaminated Soils

“…Seed germination relies almost exclusively on the seed reserves for the supply of metabolites for respiration, as well as other anabolic reactions. Starch is quantitatively the most abundant storage material in all seeds, and the available evidence indicates that in germinating seeds starch is degraded predominantly via the amylolytic pathway [26,31]. Although, the seed coat being provides some protection from metal stress prior to germination, however, it could eventually crack or become more permeable upon germination.…”
