Abstract

The Individual Influence Of Brassinosteroids Or Selenium Has Been Broadly Investigated In Many Plant And Crop Species. However, Least Reports Are Available On The Combined Effects Of Those Two On P...

Highlights

  • The potato (Solanum tuberosum L.) tuber is the third most important food crop in the world after rice and wheat for human consumption and makes an important contribution to the diet of people worldwide (Haverkort, Struik, Visser, & Jacobsen, 2009)

  • BRs are classified as C27, C28 and C29 BRs based on the number of carbons in their structure (Vardhini & Anjum, 2015) and have profound impact on plant physiology, growth and development including; seed germination (Syed Ali Fathima, Johnson, & Lingakumar, 2011), cell division (Ho, 2003; Nakaya et al, 2002), leaf expansion (Zhiponova et al, 2013), source/sink relationships and photosynthesis (Denget, 2007)

  • Se had little effect on tuber number, tuber yield or leaf chlorophyll whereas, EBL (0.14 μM) increased tuber number by 32%, tuber yield by 21% and leaf chlorophyll by 14%, relative to control

Summary

Introduction

The potato (Solanum tuberosum L.) tuber is the third most important food crop in the world after rice and wheat for human consumption and makes an important contribution to the diet of people worldwide (Haverkort, Struik, Visser, & Jacobsen, 2009). BRs are classified as C27, C28 and C29 BRs based on the number of carbons in their structure (Vardhini & Anjum, 2015) and have profound impact on plant physiology, growth and development including; seed germination (Syed Ali Fathima, Johnson, & Lingakumar, 2011), cell division (Ho, 2003; Nakaya et al, 2002), leaf expansion (Zhiponova et al, 2013), source/sink relationships and photosynthesis (Denget, 2007) They have a role in the control of excess reactive oxygen species (ROS) produced in cells under unfavorable conditions (Bailly et al, 2008). The involvement of BRs in the regulation of ROS metabolism is evident as they can promote the activity of enzymatic and non-enzymatic antioxidants
