英文摘要 | Salinity is one of major environmental problem which is limiting the agricultural production. This research was conducted to evaluate the effect of re-watering on Brassica napus L., and determination of an appropriate regime for dilution of salted water by studying photosynthetic and growth response of B. napus to salt stress and subsequent N5rLe,-s-1w1N); aacMnt3e:d3r:1imn0Ng;i.xcg2Pe+dlLaNsn-1at)ssl;2ts;wNgtearre2LeSa-ttO1mr)e4eaan(tneNtdsds10(w:Mia2t1sh.:5cNN,oacNnC1ts+rl2o:(NlN,5s,fc3o;1N:lMls2o3.w2:5:e,1NdN0c;cb32+gy: re-watering. In salt stress phase, maximum reduction in net photosynthetic rate (PN) was noted 79.54%, 80.72%, 84.54%, and 74.84% for Nc3, Ns3, M1 and M2, respectively, under high concentration levels. To maintain PN, carbonic anhydrase (CA) activity was stimulated and kept water status stable under low (Nc1 and Ns1) to medium concentration levels (Nc2, Ns2 and M3), and the decreases in PN under Nc2, Ns2 and M3 were 48.28%, 55.58% and 58.69%, respectively. However, during re- watering phase, growth and physiological parameters were recovered well due to regulation of CA activity under low to medium concentration levels. Relatively as compare to other stress levels more recovery in PN was found after re- watering under medium concentration levels, which were 44.94%, 53.45% and 63.04%, respectively. Though aimed at consideration of high production in B. napus, the best re-watering time was found to be when plants undergo medium concentration levels. Therefore, this study provides a new method for dilution of saline irrigation based on plant physiology. |
