Abstract
BackgroundOcimum basilicum was grown under three levels of drought stress (100% Field capacity, 70% Field capacity, and 40% Field capacity). Half of the plants were inoculated with Arbuscular mycorrhiza and the other half was not inoculated. Arbuscular mycorrhizal fungi (AMF) were applied to improve plant growth and to alleviate drought stress on sweet basil.ResultsDrought Couse inhibition in the colonization of Arbuscular mycorrhiza, reduction in plant growth, decrease stomatal size increase stomatal density, a decline in soluble carbohydrates, accumulation of amino acids, proline, and glycine betaine, and reduction in some minerals such as P, K, and Na.ConclusionsThe effect of drought was alleviated by the application of inoculation with Arbuscular mycorrhiza.
Highlights
Ocimum basilicum was grown under three levels of drought stress (100% Field capacity, 70% Field capacity, and 40% Field capacity)
2.1 Seeds and Mycorrhiza propagules Sweet basil (Ocimum basilicum) seeds were provided from Agricultural Research Center (ARC), Seds Station, Beni-Suef Governorate, Egypt, but the propaguled arbuscular mycorrhiza (Glomus versiform) was provided from Soil, Water and Environment Research Institute (SWERI), Agricultural Research Center (ARC), Giza, Egypt
The obtained retardation was concomitant with many similar results obtained from Mays which suffered retardation of the colonization percentage [33] and similar retardation was observed in Leymus chinensis and Hemarthria altissima grasses [34]
Summary
Ocimum basilicum was grown under three levels of drought stress (100% Field capacity, 70% Field capacity, and 40% Field capacity). Arbuscular mycorrhizal fungi (AMF) were applied to improve plant growth and to alleviate drought stress on sweet basil. Drought is defined as the deficiency of available soil moisture which may be sufficient to cause a reduction in growth, [3]. Drought stress is a major and serious threat to agriculture and crop production in arid and semiarid regions. 70% of the global available water is used in agriculture to produce about 40% of the world’s food [5]. Drought causes retardation in plant growth leading to a reduction in their yields. It disturbs plant metabolism causing inhibitions in total carbohydrates, total nitrogen contents, and total lipids [6, 7]. Several studied concerned with the negative effect of drought on plants, for example, it was observed a
