| Abstract | ||||
| The biochemical and anatomical analysis of furrow and drip-irrigated pods at harvest and after postharvest were investigated. Results showed that, furrow-irrigated pods were significantly higher in the concentration of vitamin C, free phenolics, protein and proline as well as superoxide dismutase activity than drip-irrigated ones. On the other hand, concentration of free amino acids and activity of catalase were higher in drip-irrigated pods by about 4 and 1.7 times than furrow-irrigated ones, respectively. Both types of pods were similar in chlorophylls, carotenoids, TA (%), TSS and reducing sugars concentrations. The two pod types were similar in the anatomical parameters studied except that furrow-irrigated pods which showed an increase in the thickness of parenchymatous cells in the pericarp. During storage, furrow-irrigated pods stored at 7±1°C and 85% RH for 25d showed lower % of decay, rot, soggy and shriveling, but showed more water loss than drip-irrigated ones at all storage periods. Drip-irrigated pods maintained high concentration of chlorophylls and carotenoid than furrow-irrigated pods until 20 d of storage. Furrow-irrigated pods preserve the vitamin C at high concentration at all storage periods. TA (%) and TSS were increased with storage in both fruit types without any significant differences between them. Both pod types had the same trend in the concentration of organic compounds and the activity of antioxidative enzymes. Furrow-irrigated pods maintained their pericarp and symmetric of cells compared to drip-irrigated ones. It could conclude that furrow irrigation was better to produce visual appearance, high nutritional snap beans with high quality. It can be stored without deleterious effect for 25 d at 7±1°C and 85% RH than drip irrigation. | ||||
