"Differential heat sensitivity of two cool‐season legumes, chickpea and lentil, at the reproductive stage, is associated with responses in pollen function, photosynthetic ability and oxidative damage"^^ . "Increasing temperatures are adversely affecting various food crops, including legumes,\r\nand this issue requires attention. The growth of two cool-season food legumes,\r\nchickpea and lentil, is inhibited by high temperatures but their relative sensitivity to\r\nheat stress and the underlying reasons have not been investigated. Moreover, the\r\nhigh-temperature thresholds for these two legumes have not been well-characterised.\r\nIn the present study, three chickpea (ICCVO7110, ICC5912 and ICCV92944) and\r\ntwo lentil (LL699 and LL931) genotypes, having nearly similar phenology with respect\r\nto flowering, were grown at 30/20°C (day/night; control) until the onset of flowering\r\nand subsequently exposed to varying high temperatures (35/25, 38/28, 40/30\r\nand 42/32°C; day/night) in a controlled environment (growth chamber; 12 hr/12 hr;\r\nlight intensity 750 μmol m−2 s−1; RH-70%) at 108 days after sowing for both the species.\r\nPhenology (podding, maturity) was accelerated in both the species; the days to\r\npodding declined more in lentil at 35/25 (2.8 days) and 38/28°C (11.3 days) than in\r\nchickpea (1.7 and 7.1 days, respectively). Heat stress decreased flowering–podding\r\nand podding–maturity intervals considerably in both the species. At higher temperatures,\r\nno podding was observed in lentil, while chickpea showed reduction of 14.9\r\nand 16.1 days at 40/30 and 42/32°C, respectively. Maturity was accelerated on 15.3\r\nand 12.5 days at 38/28°C, 33.6 and 34 days at 40/30°C and 45.6 and 47 days at\r\n42/32°C, in chickpea and lentil, respectively. Consequently, biomass decreased considerably\r\nat 38/28°C in both the species to limit the yield-related traits. Lentil was\r\nsignificantly more sensitive to heat stress, with the damage—assessed as reduction\r\nin biomass, reproductive function-related traits (pollen viability, germination, pollen\r\ntube growth and stigma receptivity), leaf traits such as membrane injury, leaf\r\nwater status, photochemical efficiency, chlorophyll concentration, carbon fixation\r\nand assimilation, and oxidative stress, appearing even at 35/25°C, compared with\r\n38/28°C, in chickpea. The expression of enzymatic antioxidants such as superoxide\r\ndismutase, catalase, ascorbate peroxidase, glutathione reductase and non-enzymatic antioxidants declined remarkably with heat stress, more so in lentil than in chickpea.\r\nCarbon fixation (assessed as Rubisco activity) and assimilation (assessed as sucrose\r\nconcentration, sucrose synthase activity) were also reduced more in lentil than in\r\nchickpea, at all the stressful temperatures, resulting in more inhibition of plant biomass\r\n(shoot + roots), damage to reproductive function and severe reduction in pods\r\nand seeds. At 38/28°C, lentil showed 43% reduction in biomass, while it declined by\r\n17.2% in chickpea at the same time, over the control temperature (30/20°C). At this\r\ntemperature, lentil showed 53% and 46% reduction in pods and seed yield, compared\r\nto 13.4% and 22% decrease in chickpea at the same temperature. At 40/30°C, lentil\r\ndid not produce any pods, while chickpea was able to produce few pods at this temperature.\r\nThis study identified that lentil is considerably more sensitive to heat stress\r\nthan chickpea, as a result of more damage to leaves (photosynthetic ability; oxidative\r\ninjury) and reproductive components (pollen function, etc.) at 35/25°C and above, at\r\ncontrolled conditions."^^ .
