HMs effects on plant traits |
Ref. |
Sassafras tzumu Hemsl. |
5 mg/kg-100 mg/kg Cd; 5 times in a year; 15d interval |
Inhibited sassafras growth, declined biomass yield, SOD activity, increase POD |
[39] |
Capsicum annuum L. |
5 mg Cd/kg; 7d |
Decreased growth characteristics, soluble sugars, proteins, and amino acids; increased POD, SOD, and CAT activity |
[16] |
Beta vulgaris subsp. vulgaris |
10 μM CdSO4; 14 d |
Impaired morphological traits; Occurred cellular damages |
[9] |
Oryza sativa cv. Meixiangzhan-2; Xiangyaxiangzhan |
400, 800, and 1,200 ppm Pb(NO3)2 ; growth period (145-150 d) |
Reduced chlorophyll, carotenoid; reduced yield and yield component |
[21] |
Triticum aestivum L. cv. Punjab-81, AARI-11; Kohistan-97, As-2002, Barani-70, and Pari-73 |
Plant sample collected: 5-45 μg/kg As present in grains |
Influenced chlorophyll, grain yield, biological yield, and straw yield differentially in sensitive and tolerant cultivars |
[40] |
Medicago sativa L. |
40 μM Hg; 14 d |
Declined morphological and photosynthetic, and yield traits |
[10] |
Brassica napus L. |
5-20 mg/L Hg; 10d |
Inhibited the growth, biomass yield, and nutrient accumulation |
[41] |
Triticum aestivum L. |
2.5-25 μM Hg; |
Inhibited root and shoot growth, content of chlorophyll and total soluble protein |
[42] |
Oryza sativa L. cv. normal and hybrid |
100 µM K2Cr2O7; 14 d |
Influence germination energy (%),percentage (%),index (%), time (%), and vigor index |
[35] |
Miscanthus sinensis Andersson. cv. Kosung |
50-1000 μM K2Cr2O7; 3d |
Inhibited root growth and plant biomass yield, altered oxidative stress indicator and protein content |
[43] |
