Abstract
Vegetables require an optimum supply of mineral elements like silicon (Si). Si is second to oxygen in its abundance in the earth crust, and its role is quite significant in tackling biotic and abiotic stresses of vegetables. Si application also improves several agronomic and quality traits of vegetables. Hence, Si application is recommended as a strategy for the improvement of vegetable crops production. Although the research about the role of Si in vegetable dicots still lags far behind than cereals. Recently, omics-based approaches were used to provide a deeper understanding of the role of Si in vegetable protection. Here, we have compiled the studies focusing on the role of Si for vegetables, thus, enabling all of the important information regarding the effect Si application to vegetables at one place.
Highlights
Vegetables are vulnerable to a wide range of biotic and abiotic stresses; to overcome these stresses, vegetables requires an optimum supply of macro and micronutrients [1,2,3]
We have discussed the role of Si application in protecting vegetable crops against several biotic and abiotic stresses
With the advancement in the omics-based approaches, information regarding the role of Si, in shaping vegetable crops protection against abiotic and biotic stress is increasing
Summary
Vegetables are vulnerable to a wide range of biotic and abiotic stresses; to overcome these stresses, vegetables requires an optimum supply of macro and micronutrients [1,2,3]. Presently there are a limited number of studies which demonstrate there are advantages of Si application for greenhouse crops. In vegetables, Si application has been documented to reduce the attack of diseases [11]. Plants 2019, 8, 148 postharvest diseases of vegetables [16,17] In this direction, studies have demonstrated that higher. Correa et al [19] reported that soil or as a foliar spray of Si as calcium silicate to cucumber plants increases the mortality of the nymphs of Bemisia tabaci. Several abiotic stresses affecting the vegetables are eradicated by the application of Si [20]. In many of the recent reviews on the role of Si in plants, the vegetable crops are underrepresented [24,25,26]. We have structured our review focusing on the role of Si application for vegetables, especially, in tackling biotic and abiotic stresses, as well as the role of Si application on agronomic and quality traits of vegetables, collating all of the important information regarding the effect of Si application to vegetables in one place
