“…Many studies have shown that aphid infestation can trigger severe Chl breakdown within the host. An imbalance between biosynthesis and catabolic turnover of green pigments in plant tissues indicates profound inhibition of photosynthesis process (Heng-Moss et al, 2003;Smith et al, 2005;Botha et al, 2006;Diaz-Montano et al, 2007;Goławska et al, 2010). Portable leaf-clip-type chlorophyll meters perform rapid, repetitive and nondestructive estimates of Chl concentrations in living plants (Hawkins et al, 2009;Jinwen et al, 2009;Coste et al, 2010;Gholizadeh et al, 2011;Shrestha et al, 2012;Ghosh et al, 2013).…”
