“…However, a plausible explanation can be offered that P n drastically reduced in flooded plants up to 3-days because of both stomatal and non-stomatal limitations, and thereafter, plants could acclimatize to flooding situation and non-stomatal limitation became dominant. This is also in agreement with the report by Beckman et al (1992) and Kozlowski and Pallardy (1984) that photosynthesis of flooded plants appears to be reduced first primarily because of stomatal closure and later by a reduction in photosynthetic capacity. Genotypic differences in recovery of P n were highly evident at vegetative and flowering stages.…”

Flooding-induced changes in leaf gas exchanges, grain yield, and yield-related parameters of mungbean were evaluated employing two flood-tolerant (GK48 and VC3945A) and one flood-susceptible (Vo1982A-G) genotypes. Three flooding regimes viz. 1, 3 and 7-day were imposed at vegetative, flowering, and pod-fill stages. Flooding caused a drastic reduction in photosynthesis rates (P n ), irrespective of flooding duration. However, the flooded plants recovered P n to a large extent depending on genotypes. Used genotypes showed a significant variation in P n during and after flooding. Post-flooding recovery in P n of GK48 and VC3945A was more pronounced at the vegetative and flowering stages than the pod-fill stage. At the pod-fill stage, only plants of GK48 survived when flooding prolonged for 7 days. Flooded plants showed higher intercellular CO 2 concentrations (C i ), and reduced stomatal conductance (g s ). However, during recovery, P n increased significantly along with reduced C i in flood-tolerant GK48 and VC3945A genotypes. In contrast, C i remained high and P n recovery was minimal in floodsusceptible Vo1982A-G genotype. This implies that mesophyll tolerance rather than stomatal factor might be the major limitation of P n recovery in a susceptible genotype. Very weak relationship between P n and transpiration rate (T r ) indicated low water use efficiency (WUE) in flooded plants, but subsequent recovery of both the parameters, suggesting higher WUE, particularly in tolerant genotypes. Seed yield of mungbean was the product of number of pods per plant and seed size, and longer the flooding period, the lower were the pods per plant at the flowering and pod-fill stage. Flooding reduced seed yield in all the three genotypes, but the extent of reduction was much less in flood-tolerant GK48 and VC3945A. Higher yield of flood-tolerant genotypes may be attributed to the rapid recovery of leaf gas exchanges.

“…Stomatal closure hinders CO 2 absorption, on the other hand, hypoxia induced by waterlogging inhibits synthesis of 8-amino-propyl acetate (5-ALA), the speed limit step of chlorophyll synthesis. Reduced CO 2 -fixation ability of chloroplast and chemical changes of PSII system will lead to significant decrease in leaf photosynthetic rate (Beckman et al 1992, Olien 1989. Our results showed that the photosynthetic rate and stomatal conductance of the five pepper species and wild pepper dramatically decreased under waterlogging condition and their recovery to normal levels after the drainage is lagged behind and needs time, indicating that pepper is not a good waterlogging-tolerant plant.…”

One of the effective ways to address the effects of abnormal climate change on plant is to find germplasms that have better resistance to adverse environments. In this paper, we studied the responses of 5 pepper species Capsicum annuum L. (CA), C. baccatum L. (CB), C. chinense Jacquin. (CC), C. frutescens L. (CF) and C. pubescens Ruiz & Pavon (CP) as well as a wild pepper C. baccatum var. baccatum (CBY) to waterlogging stress. The results showed that warterlogging treatment greatly decreases photosynthetic pigment content, net photosynthetic rate (P N ) and stomatal conductance (g s ), and dramatically increases proline content and water-use efficiency (WUE) in all tested pepper, suggesting that pepper has weak resistance to waterlogging stress. The results also showed that changes of the above parameters vary in different species. CP had the smallest decreases in photosynthetic pigment content, P N , and g s and greatest increases in proline content and WUE. By contrast, CC had the greatest decreases in photosynthetic pigment content, P N , and g s and smallest increases in proline content and WUE, indicating that different species had different resistance to adverse environment and species CP and CC had the strongest and the weakest resistances, respectively. In addition, the study also demonstrated that wild pepper CBY had better resistance to adverse environment than all the tested species, indicating loss of the stress resistance genes during the process of domestication. Taking together, our study strongly suggests that pepper species should crossbreed with other species and wild pepper to expand genetic diversity, enlarge genetic distance, promote production, and improve the resistance to adverse environments.

The effect of short-term flooding was examined in 2-year-old apricot trees (Prunus armeniaca cv. Búlida). Six apricot trees of similar appearance were submitted to two treatments: three were irrigated daily, while the others were flooded for a period of 50 h by submerging the pots in plastic water tanks. The trees were removed from the water, drained and then placed in the same conditions as the control plants. A decrease in transpiration in the flooded trees with respect to the control plants was evident. The daily pattern of soil O 2 concentration and plant hydraulic resistance followed a similar trend during the flooding. However, this relationship was not maintained throughout the experiment, since the O 2 values increased rapidly when the waterlogging ceased, while plant hydraulic resistance only recovered at the end of the experiment when the original root system, damaged by flooded conditions, was replaced with new roots. In flooded trees, the midday leaf water potential decreased progressively from the beginning of flooding, but gradually recovered when the waterlogging ceased. Leaf conductance values of treated plants were slow to recover, reaching values of the control plants 8 days after the leaf water potential had recovered. The close relationship observed during most of the experiment between the leaf water parameters, leaf conductance and plant hydraulic conductance indicate that hydraulic messages are likely to play a dominant role in co-ordinating the observed responses of the shoot.
