“…Technical-hexachloro cyclohexane (tech-HCH) was shown to inhibit the germination of radish and green gram seeds [20]. Adverse effect of systemic fungicide (Topsin-M) and insecticide (Dimecron) on germination and seedling growth of Pennisetum americanum L. has been reported [21]. Complete inhibition of germination of tomato seeds on exposure to 3-chlorobenzoate (3-CBA) and 4-chlorobenzoate (4-CBA) was observed [22].…”

Phenol is one of the 50 bulkiest chemicals produced in the world and is one of the priority pollutants found in various industrial effluents at varying levels. Its toxicity to fauna and flora has been well established. However, information on its effect on germination of crop seeds is scanty. In this study the effects of phenol on germination of 11 different crop seeds were tested by filter paper as well as soil methods. Chickpea, mung bean, and long-podded cowpea seeds were found to be highly sensitive with drastic reduction in germination percentage (GP) and seedling vigour (SV) in the presence of phenol even at very low concentrations, chickpea being most vulnerable. Marked decrease in protease and amylase activities in germinating seeds was also observed. Seed viability was inversely proportional to the concentration of phenol. The inhibitory effect of phenol on germination was eliminated effectively by bioaugmentation of the soil with Pseudomonas aeruginosa S-CSR-0013. Pre-inoculation of the soil eight days before sowing the seeds exhibited complete protection of GP and SV. The bacterium degraded phenol efficiently from the soil with concomitant growth. It can be concluded that phenol-contaminated soils could be effectively bioremediated to enable normal seed germination and seedling growth.

The possible physiological mechanisms behind the allelopathic effects of three concentrations of black pepper (Piper nigrum) whole plants leachings on germination, seedling growth, chlorophyll and chlorophyll supply-orientation (precursors for chlorophyll biosynthesis) in Vigna mungo var. NIAB were investigated. Fifty and 75% leaching solutions negatively affected germination and seedling growth of V. mungo. Maximum inhibition (58.11%) was recorded in germination at 75% leaching-treated seeds. In addition, seedling growth was also retarded by the application of leachings. Especially the affect on shoot growth was more evident with the increasing concentrations compared to root growth. In other experiment 10-day old etiolated seedlings of V. mungo were cultured in growth chamber in one-tenth Hoagland culture solution with or without leaching-concentrations. Leaves were harvested randomly at 0, 6, 12, 24 and 48-h time interval after treatment. The concentrations of chlorophyll, porphyrin and its three biosynthetic precursors such as proto porphyrin IX (Proto), Mg-proto porphyrin IX (Mg-Proto), and proto-chlorophyllide (Pchlide) were determined. Synthesis of chlorophyll and porphyrin was inhibited as the leaching concentrations increased. The mole percent of Mg-Proto affected by the leachings exhibited the same pattern as that of Pchlide and Proto. The data suggest that enzymes responsible for the conversion of porphyrin precursors may be the major targets of the leaching causing the significant decrease in chlorophyll concentration.
