Senescence of rice leaves XXXI. Changes of chlorophyll, protein, and polyamine contents and ethylene production during senescence of a chlorophyll-deficient mutant

Effect of Split Application of Nitrogen Fertilizer on Leaf Color Chart Values in Hybrid Rice (GRH1)

“…When application fertilizer at the fixed timing basal-tillering ( application (Sen et al, 2011). Chen (1991 reported that the chlorophyll level in the normal leaves decreased progressively with age.…”

Polyamines, indole-3-acetic acid and abscisic acid in rice phloem sap

“…[1] identified Put, Spd and Spm from leaves of a rice cultivar Norin No . 8 ., where the contents of Spd and Spm were nearly comparable to our data but the Put contents was much lower .…”

“…However, nothing has been investigated on the transport of endogenous plant growth regulators in rice phloem sap, although phloem sap of other various plants has been examined for plant hormones such as gibberellins [10,21], indole-3-acetic acid (IAA) [6,12], abscisic acid (ABA) [7,8,9,21] and cytokinins [21], as well as polyamines [5] . In contrast, rice tissue was analyzed for a variety of endogenous growth regulators such as gibberellins [13], cytokinins [18], auxins [12], ABA [17] and polyamines [1,15] in relation to the growth of rice.…”

Exogenous application of nitric oxide and thiourea regulates on growth and some key physiological processes in maize (Zea mays L.) plants under saline stress.

“…The increase in electrolyte leakage recorded under salt stress could be partly due to the decreased chlorophyll content (Kaya et al, 2001). Increased electrolyte leakage was reported to be associated with reductions in leaf senescenc-induced chlorophyll concentration (Dhindsa et al, 1981;Chen et al, 1991). Increase in the EL values of salinized plants was higher in the salt sensitive cultivar Apex 836 than that in salt tolerant cultivar Table 1.…”
