“…The seedling vigor was high at 50 mgL -1 when compared to that of control and decreased gradually with increase in concentration, but it was still higher than that of control. Recently, Parveen and Rao (2015) reported that the Ag NPs caused enhanced seedling growth in Pennisetum glaucum plant when the same amount of NPs was treated. This result was comparable to our study obtained here for Fe 2 O 3 NPs on S. lycopersicum.…”

“…Due to their different morphologies of nanomaterials, it is difficult to predict the positive or negative effect in their mode of action in environment and within living systems (Holsapple et al 2005). In fact, the phytotoxic affects of MWCNTs (rice) (Lin et al 2009), magnetic NPs (pumpkin) (González-Melendi et al 2008;Zhu et al 2008), copper NPs (zucchini) (Stampoulis et al 2009) and silver NPs (onion, pearl millet) (Kumari et al 2009;Parveen and Rao 2015) have been studied in addition to their effect on seed germination and elongation of root/plant growth. These studies show contradictory results (both positive and negative effect) on different plant species when the same nanomaterial is used.…”

In the present study, we demonstrate magnetic iron (III) oxide nanoparticles (Fe 2 O 3 NPs) uptake by the Solanum lycopersicum (S. lycopersicum) plant. The S. lycopersicum seeds were coated with Fe 2 O 3 NPs and allowed to germinate in moistened sand bed. The seedlings are observed for 20 days, and then, it was post-treated using different amounts of Fe 2 O 3 NPs in hydroponic solution for 10 days. The plant was allowed to grow in green house for 3 months, and uptake of NPs through roots and translocation into different parts was studied. For this, we have segmented the plants and incubated with 10 % NaOH solution. It is found that the NPs are deposited preferentially in root hairs, root tips followed by nodal and middle zone of plant. The iron present in the whole plant was quantitatively estimated by treating dry biomass of the plant in acid. The Fe 2? /Fe total increased with increasing concentration of NPs and [45 % ferrous iron suggests the biomineralization of NPs due to rich phytochemicals in plants. We believe that the present study is useful to build a base line data for novel applications in agrinanotechnology.

“…In contrast, CuO NPs decreased the germination seeds, shoot length and shoot weight of rice [7], CNTs could obviously inhibit seed gernintion of L. Sativum in sewage sludge. Ag NPs increased the germination percent of Pennisetum glaucum [8]. Meanwhile more investigations reported that nanopaticles had no effect on germination but did influence the growth of plants.…”

“…Pearl millet (Pennisetum glaucum) seeds need to be washed previously with liquid soap solution and bavistin (fungicide) for 3 min and rinsed twice with deionised water [44]. Then they must be placed in Petri dishes (90 mm in diameter), containing one moisted piece of filter paper Whatman no.…”

“…Then they must be placed in Petri dishes (90 mm in diameter), containing one moisted piece of filter paper Whatman no. 1, and after that they have to be covered and maintained on a lab bench at room temperature (30 ± 5°C) [44]. An incubator programme of 30/19°C 16 h/8 h has also been successfully used [45].…”

New Challenges in Seed Biology - Basic and Translational Research Driving Seed Technology

Constructed green wetlands with horizontal surface for wastewater treatment are gaining acceptance. Many countries have published innovative experiences with this technology. A great variety of wastewaters from industries have been treated. Different plant species have been tested. Seed technology development provides interesting tools to produce these species in nurseries. It is a sustainable new business. But studies on seed germination of aquatic and lacustrine plants are very few. That is why we have made the following bibliographic review. We have summarised and analysed the state of the art of this innovative topic, concluding that seed technology for multiplication of helophytes needs further experimental work. But there is enough information to produce right now, tens of different species. Significant efforts have been done. Even though it is a challenge to produce from now on, experimental results are ready to be transferred to those who are trading with this type of plants. Helophytes have a promising future as sustainable elements of the upcoming sewage equipment. Improvements on the biotechnology of these species are a worthwhile researching line. To this aim, the following revision is an essential compilation with which to begin.Various authors have highlighted that studies on seed germination of aquatic and lacustrine plants are very few [13]. This topic is a much less studied subject that other aspects of seed biology, physiology or ecology. However it has a great importance from an applied point of view. That is why we have made the following bibliographic review. It will let us summarise and analyse the state of the art of this interesting topic.
