“…Related to drought stress is transplanting shock. According to Page and Awarau (2012) Envy™ is widely used by farmers in Queensland, Australia, as a pre-transplanting treatment to reduce water loss after transplanting. Improving fruit size and protecting pome fruits against sunburn and improving size of fruit vegetables like tomatoes and cucurbits are the other key uses of film-forming ATs.…”

Commercial uses of antitranspirants in crop production: A review

Global food security is at risk due to the predicted climate change, making it imperative for agronomists to provide adaptive technologies that will sustain and improve food production. Rainfed agriculture, prone to drought, covers an estimated 80% of global cropland. One of the adaptive technologies is the use of antitranspirants – products that are applied on plants to reduce transpirational water loss and increase crop performance under drought conditions. The benefits of improving antitranspirant adoption in drought mitigation are expected to be high, especially in many drought-prone low-income countries where crop production is almost wholly dependent on rainfall. The objective of this article was to review the commercial uses of antitranspirants in food and non-food crop production. The review revealed that in horticulture, antitranspirants have several commercial uses, in addition to drought mitigation, such as transplanting shock amelioration, protection of fruit against sunburn, enhancement of nutritional quality, synchronising fruit ripening, protection of fruit and nut trees against diseases. Use of antitranspirants in arable farming has been neglected for three main reasons: first, arable crops have lower market value, for example, in Melbourne (Australia) in October 2022, a tonne of grapes was worth US$ 2694.82 compared to US$ 277/tonne of wheat. Second, molecular genetics applied to crop breeding has risen as an alternative approach to drought mitigation, shifting attention from antitranspirants. Finally, the erroneous research conclusion in the 1970s that antitranspirants could not increase yield because they reduced photosynthesis discouraged commercialisation of antitranspirants in arable farming. An antitranspirant breakthrough to either lower the cost or create a multi-purpose product is needed for the production of arable crops, especially major cereals, as has been the case for non-drought amelioration uses in horticulture.

“…However, it has been shown that Aquilaria adapts easily to new environment, resulting in many Aquilaria plantations in sourcing countries been planted with nonnative species. For example, successful Aquilaria plantations have been established in Australia, a region that is beyond the tree natural distribution (Page and Awarau 2012 ). In Malaysia, where A. malaccensis is native, people have succeeded in planting A. crassna and A. subintegra species as well.…”

The resinous portion of the Aquilaria tree is called agarwood, a valuable non-timber product being used as medicine and incenses in Asia, Middle East, and Europe. Driven by high demand, the wild resources of agarwood-producing trees have been greatly threatened. This fragrant product contains many aromatic substances and is obtained from the pathological conditions of the wood of living trees. The knowledge regarding the technology for inducing agarwood and its continuous formation in the tree is still limited. To conserve the wild Aquilaria spp. and to supply sustainable amount of agarwood, cultivation of Aquilaria trees in combination with induction through artifi cial technique is seen as the best approach. In this chapter we will discuss the fundamentals of agarwood formation in the producing trees, the molecular pathway in its synthesis, current methods applied for agarwood induction in cultivated trees, and fi nally the factors infl uencing agarwood yield and quality.

“…The demand for and trade in agarwood continues today, and with in-creasing wealth in consumer countries over recent decades, demand exceeds supply (Barden et al, 2000;Compton and Ishihara, 2006) [15,32] . This has resulted in increased prices (Wyn and Anak 2010) [116] , natural resource decline (Zhang et al 2008) [122] , reduction in product quality (Antonopoulou et al, 2010) [8] , increasing interest in cultivation (Hoang and Nghi, 2011; Page and Awarau, 2012;Persoon, 2008;Rahman et al, 2015) [49,80,84,88] , and developing methods for resin induction (Liu et al, 2013;Mohamed et al, 2014;Persoon, 2008) [67,84,77] . In Japan, it is known asjinkoh (also means the sinking incense) (Brechbill, 2012) [22] .…”

Aquilaria species have been the primary source for agarwood and are distributed eastward from India (Bengal and Assam) to the island of New Guinea and southward from tropical China. Agarwood is dark resinous heartwood that forms in Aquilaria and Gyrinops trees in the plant family Thymelaeaceae. Agarwood has been used for medicinal purposes for thousands of years, and continues to be used in Ayurvedic, Tibetan and traditional East Asian medicine. High-grade agarwood powder is used for aromatherapy and also used in the production of pharmaceutical tinctures. The number and types of agarwood metabolite constituents of each reported studies vary depending on the agarwood source, extraction methods and analysis approaches used. Agarwood, also known as eaglewood or gaharu, is a valuable non-timber forest product which sometimes grows in Aquilaria species. The genus species occur mainly in South and Southeast Asia. As a result of a defense mechanism to fend off pathogens, Aquilaria species develop agarwood which can be used for incense, perfume, and traditional medicines. The main markets for these products are in South and East Asia and the Middle East. The high prices demanded for agarwood has led to the rapid depletion of Aquilaria trees in natural forests. The search for agarwood has spread from one country to another. Efforts have been undertaken to increase the production of the infected wood by deliberately wounding the trees. A variety of methods is used towards this end. Some recently developed techniques have proven to be most effective. This resulted in planting of Aquilaria trees by small holders as well as large industrial size plantations. In this paper, we shall discuss all the concerns of agarwood for better yield, quality and maximum utilities for humanity as well as the environment safety to enhance the socio economic condition of the Pakistan.
