“…Similar results were obtained in Brassica napus 'GSL 1' (Pahwa et al, 2009) and barley (Zhang et al, 2006) leaves. Qian et al (2009) showed that low SNP concentrations (20 µM) increased the leaf chlorophyll content in Chlorella vulgaris plants, whereas high SNP levels (100 µM) inhibited their chlorophyll content, showing that the increase or decrease in chlorophyll content was associated with the enhanced or inhibited expression of photosynthesis genes, respectively (Qian et al, 2009).…”

The effects of sodium nitroprusside (SNP) on micropropagation of CAB-6P and Gisela 6 cherry rootstocks were investigated. Shoot multiplication of CAB-6P was reduced by adding 4.4 µM 6-benzylaminopurine (BA) and SNP. Gisela 6 microcuttings treated with BA + 30 µM SNP gave the highest average shoot number (4.15) and multiplication percentage (100%). In CAB-6P, α-naphthaleneacetic acid (NAA) + 30 µM SNP led to the maximum root number (13.79) and fresh weight (0.336 g); average root length (82 mm) and rooting percentage (95.45%) were greatest after adding 40 and 10 µM SNP + NAA, respectively. In Gisela 6, NAA + 40 µM SNP resulted in the highest root number (9.75) and fresh weight (0.238 g), while NAA + 30 µM SNP enabled maximum root length (30.77 mm). Rooting percentage was greatest (84.62%) when Gisela 6 microcuttings were treated only with NAA. Application of SNP alone in CAB-6P reduced leaf chlorophyll, carbohydrate, and prοline levels. In contrast, 30-50 µM SNP increased leaf chlorophyll levels of Gisela 6. SNP augmented leaf carbohydrate and proline content, but it diminished root carbohydrate content. In BA + SNP or NAA + SNP treatments, changes in biochemical constituents were dependent on SNP concentrations and genotypes.

“…Our data showed that the activities of POD and PAL elevated when chili plants were inoculated and treated with SNP, and their activities reached the peak after treating for 15 and 48 h respectively. Some research shows that SNP could induce activities of POD and PAL enzymes in Cholrella vugaris [19], tomatoes fruit [13], tomatoes fruit [34] and sweet potato root [30].…”

Abstract:The study on the induction of plant defense against to anthracnose disease of chili by sodium nitroprusside solution was investigated during pre-and post-harvest. Pre-harvest treatment was conducted by spraying the chili plants with sodium nitroprusside (SNP, nitric oxide donor) solution at 0 (control), 0.05 and 0.1 mM every 3 days for 9 times before inoculating with the spore suspension of Colletotrichum gloeosporioides (the causal agent of anthracnose disease) and then sprayed with SNP again 1 time after inoculating. The results revealed that 0.1 mM SNP was the best concentration to suppress anthracnose disease by reducing disease incidence and disease index on chili leaves, and showing the lowest loss of yield caused by anthracnose disease. This founding also showed that either pathogenic inoculation or SNP treatment had ability to induce the activities of peroxidase (POD) and phenylalanine ammonia lyase (PAL) of chili leaves, particularly the chili plant inoculated with pathogenic fungi followed by treated with 0.1 mM SNP showed the highest POD and PAL activities. Postharvest treatment was done by inoculating the mature chilli fruit with C. capcisi for 4 h and followed by dipping in 0 (control) and 4 mM SNP. All fruit samples were kept at 13°C for 15 days. The results showed that chili fruit dipped with 4 mM SNP reduced disease incidence, disease index, delayed weight loss, respiration rate, ethylene production, and also maintained the changes of fruit color (∆E) better than non-treated fruit (control). The activities of chitinase (CHI) and β-1,3-glucanase )GLU( in chili fruit were induced by SNP with the highest peak on day 6 of storage but they were not significant different with the control fruit. These results indicated that SNP might potential leading to the reduction of anthracnose disease in chili by eliciting plant defense related enzymes in both pre-and post-harvest periods.

“…NO is involved in different aspects of plant metabolism, physiology and defense (Neill et al, 2007). Recent evidences demonstrate that NO takes part in the regulation of plant defense response to abiotic and biotic stresses, such as drought, salinity, heat stress, heavy metals, UV-B radiation and disease resistance (Arasimowicz and Floryszak-Wieczorek, 2007;Zhao et al, 2008;Qian et al, 2009). For instance, exogenous NO could alleviate damages caused by Cu toxicity and herbicide in algae (Singh et al, 2004;Qian et al, 2009).…”

For instance, exogenous NO could alleviate damages caused by Cu toxicity and herbicide in algae (Singh et al, 2004;Qian et al, 2009). The observed protective effect of exogenous NO was assumed to be related with the antioxidative action of NO, the elevation of activity of antioxidative enzymes, functional cooperation with other signal molecules and modulation of gene expression (Arasimowicz and Floryszak-Wieczorek, 2007).…”
