“…This is also consistent with the absence of significant changes in chlorophyll concentrations under salt stress conditions [63]. However, similar results were found in Lagernaria siceraria, the bottle gourd, but the local varieties revealed enhanced stomatal regulation indicating better acclimation to water stress [51], so this parameter should be analysed in future trials.…”

Are Traditional Lima Bean (Phaseolus lunatus L.) Landraces Valuable to Cope with Climate Change? Effects of Drought on Growth and Biochemical Stress Markers

Agrobiodiversity and adaptability to environmental changes derived from global warming are challenges for the future of agriculture. In this sense, landraces often have high levels of genetic variation, tightly connected with the changing environmental conditions of a territory. The genus Phaseolus, with five domesticated species, is one of the most important sources of proteins, carbohydrates and micronutrients in various countries. This study aimed to compare the adaptation capacity to drought, in the vegetative growth phase, of a commercial cultivar and two landraces traditionally cultivated in the Mediterranean basin of Phaseolus lunatus (Lima bean). Growth and biochemical responses of the analysed genotypes to different water-deficit treatments were evaluated and compared. In addition, the effectiveness of the voltammetric method for evaluating stress levels in cultivated plants was tested. The studied parameters revealed that P. lunatus is a drought-tolerant species, showing similar results for the three cultivars. However, contrary to what was expected from the germination phase results, the commercial variety Peru showed some better responses under water stress conditions. Finally, the voltammetric method proved to be a good and fast tool for assessing oxidative stress in cultivated plants, showing results in agreement with total phenolic compounds and total flavonoid fluctuations.

“…Growth parameters showed a similar response under water stress conditions in traditional and commercial maize varieties, except for the emergence of more leaves in landraces. Similar responses in growth and some biochemical parameters in conditions of decreasing water availability were also observed in Lagenaria siceraria cultivars [51].…”

“…Although shoot harvesting is beneficial, it can injure plants and make them prone to environmental stress, pests and fungal attacks, which lowers plant hardiness and productivity [ 30 ]. The seven- and sometimes fourteen-day shoot harvest intervals in the current study ( Table 2 ) were different from the ten-day interval harvest period among L. siceraria landraces in Zimbabwe [ 31 ]. The extended time between harvest intervals allowed landraces in the comparative study more time to accumulate more photosynthetic assimilates, and subsequently promoted the development of longer shoots [ 13 ].…”

Lagenaria siceraria (Molina) Standley is a prominent food source as almost all its plant parts are edible. However, no studies have recorded the changes in shoots, peduncles and fruits during its growth. Hence, this study aimed to record changes in shoot traits and relate the peduncle to the fruit traits of L. siceraria landraces across different growth stages. Changes in shoots, peduncles and fruits during growth were compared within and among landraces using analysis of variance, correlation, principal component analysis, cluster analysis and heritability estimates. Almost all landraces had harvestable shoots at 42 days after sowing. Peduncles became shorter and wider as the fruits elongated. Shoots, peduncles and fruits correlated positively with each other. The informative principal components had a total variability of 84.488%, with a major contribution from shoot traits. The biplot and dendrogram clustered landraces with similar growth habits and the harvestable shoot and fruit attributes into three clusters, but KRI and NSRC formed singlets. Shoot width (60.2%) and peduncle length (55.2%) had high heritability estimates. The general low heritability estimates and genetic advances indicated the presence of non-additive gene action. This study is the first report on changes in harvested shoots and the relationship between peduncles and fruits during growth.

“…Drought occurrence (Sithole and Modi, 2015), poor inherent soil properties, soil degradation, in the adequate application and incorrect timing of fertilizer (Chuma et al, 2000) (Phillips, 2015;Findlay, 2015) which ultimately led to yield gains in maize in some subsistence (Phillips, 2012) and most commercial farmers in most of the dry regions of South Africa (Table 1). Figure 1 below shows a rough estimation of CA adoption in South Africa where Western Cape Province is leading with more than 70% followed by the Province of KwaZulu-Natal with 50-60%.…”
