Treatment of wheat plants with nano chitosan NPK fertilizer induced signif icant increases in all yield parameters, as compared with control yield parameters of normal non -fertilized and normal fertilized NPK wheat plants. Transmission electron microscopy investigations showed that nanoparticles were present in phloem tissues whi ch mean that nanoparticles were taken up and transported through phloem route from leaves to stem down to roots. Clay-sandy soil showed better results than those obtained for clay soil. Foliar application of nano fertilizer to wheat plants proved to be important to improve yield parameters of wheat plants and shorten the life cycle of the crop.

“…Zinc and selenium, for example, are nutrients that can be effectively provided to humans via micronutrient fertilization of crops (Bell and Dell 2008). A patent (He et al 2009) and several publications have investigated the use of ZnO nanoparticles on a variety of crops such as cucumber (Zhao et al 2013), peanuts (Prasad et al 2012), sweet basil (El-Kereti et al 2014), cabbage, cauliflower, tomato (Singh et al 2013), and chickpea (Pandey et al 2010). Figure 2.4 shows a TEM image of nano-ZnO applied to peanut seeds, resulting in greater seed germination, seedling vigor, and chlorophyll content, as well as increased stem and root growth.…”

“…Another study examining a variety of crops noted that nano-ZnO increased seed germination while a bulk form of ZnO used for comparison had a negative impact on germination. The nano-treatment increased pigments, protein and sugar contents, and nitrate reductase activities, and other antioxidant enzyme activities were increased (Singh et al 2013). In a study on chickpeas exposed to nano-ZnO (20-30 nm), in addition to increased seed germination and root growth, higher levels of a plant growth hormone, indoleacetic acid (IAA), were observed (Pandey et al 2010).…”

The field of nanotechnology has seen tremendous growth over the past decade and has had a measurable impact on all facets of our society, from electronics to medicine. Nevertheless, nanotechnology applications in the agricultural sector are still relatively underdeveloped. Nanotechnology has the potential to provide solutions for fundamental agricultural problems caused by conventional fertilizer management. Through this chapter, we aim to highlight opportunities for the intervention of nanotechnologies in the area of fertilizers and plant nutrition and to provide a snapshot of the current state of nanotechnology in this area. This chapter will explore three themes in nanotechnology implementation for fertilizers: nanofertilizer inputs, nanoscale additives that influence plant growth and health, and nanoscale coatings/host materials for fertilizers. This chapter will also explore the potential directions that nanotechnology in fertilizers may take in the next 5-10 years as well as the potential pitfalls that should be examined and avoided.

Strategies of leaf water uptake based on anatomical traits

The ability of leaves to absorb fog water can positively contribute to the water and carbon balance of plants in montane ecosystems, especially in periods of soil water deficit. However, the ecophysiological traits and mechanisms responsible for variations in the speed and total water absorption capacity of leaves are still poorly known. This study investigated leaf anatomical attributes of seven species occurring in seasonal tropical high-altitude ecosystems (rocky outcrop and forest), which could explain differences in leaf water uptake (LWU) capacities. We tested the hypothesis that different sets of anatomical leaf attributes will be more marked in plant individuals living under these contrasting environmental conditions. Anatomical variations will affect the initial rate of water absorption and the total storage capacity, resulting in different strategies for using the water supplied by fog events. Water absorption by leaves was inferred indirectly, based on leaf anatomical structure and visual observation of the main access routes (using an apoplastic marker), the diffusion of water through the cuticle, and non-glandular or glandular trichomes in all species. The results suggest that three LWU strategies coexist in the species studied. The different anatomical patterns influenced the speed and maximum LWU capacity. The three LWU strategies can provide different adaptive advantages to adjust to temporal and spatial variations of water availability in these tropical high-altitude environments.
