“…On the other hand, no significant changes in germination were found in Bola Roja, while in Cargamanto, germination increased only under low salinity. Our results support the theory, reported by many authors [58][59][60][61], that salt response after seed priming is species-or even cultivar-specific and there is no universally effective type of treatment to increase plant tolerance to salt.…”

Common bean (Phaseolus vulgaris L.), one of the most important cultivated legumes, requires a high level of water. It is included among the most sensitive species to climate change; drought and salinity cause a reduction in photosynthesis, metabolic and enzymatic alterations, and oxidative stress. To improve crop tolerance to salt, seed priming and acclimation can be useful tools. To test the salt tolerance of beans, a preliminary screening was undertaken on four cultivars of P. vulgaris (Black Turtle, Cargamanto, Bola Roja, Borlotto) by exposing the seeds to different levels of salinity. The salt-sensitive cultivar Borlotto was chosen for experimental greenhouse trials to study the effects of halopriming and acclimation. Primed and non-primed seeds were sown in non-saline soil and acclimated for 2 weeks; then, the plants were watered with non-saline and saline solutions for 4 weeks. At the end of this growth period, the primed plants showed a marked increase in salt stress tolerance, improving the chlorophyll content, phenolic compounds, and many enzymes’ activities, in turn reducing the effect of salt on growth and fruit production compared to the non-primed controls. In conclusion, halopriming can be considered a useful tool to enhance salinity tolerance in beans and other salt-sensitive crops.

“…The response of the seed to temperature and water stress varies with different ecological environments and its own characteristics S. europaea demonstrates some degree of low-temperature tolerance and can germinate at temperature as low as 10°C and even lower, but the germination percentage and germination time of the seeds were seriously affected. Unfavorable germination temperature can disrupt the physiological and biochemical processes of the seeds (Monajjem et al 2023), Each plant species has an optimal germination temperature range, and for Salicornia, this range falls between 20°C to 35°C(Ajmal Khan et al 2000, Ungar 1977). Our study con rmed that Salicornia europaea L. germinates most effectively at temperatures between 20°C to 25°C.…”

Salicornia europaea L. is a salt-tolerant wetland plant with great economic value, but the population of S. europaea has been drastically reduced because its survival environment is seriously threatened. In this study, from the perspective of the germination stage of S. europaea, the relationship between the germination of S. europaea and different abiotic factors was investigated, the possible causes of environmental changes leading to the degradation of this species in coastal wetlands was explored, and the direction of wetland restoration, and optimized the conditions for artificial germination of S. europaea seeds was proposed. The results showed that S. europaea was sensitive to changes of GA3 concentration, salinity and temperature during the germination stage, the effect of water immersion treatment on seed germination was concentrated in the late stage of germination, and high salinity, low temperature and prolonged submergence of the seeds all led to limited seed germination. Meanwhile, the combination of analytic hierarchy process and orthogonal experiments were used to screen the range of these factors and the combination of optimal germination conditions, The optimal combined germination conditions was identified as 2000 mg/L gibberellin, 5‰ culture salinity, 20 ℃ culture temperature and 12-hour soaking time. and was validated having practical significance. In conclusion, the results of this study provide an insight to the relationship between degradation of wetland plant populations and abiotic factors, and help in the conservation of plant diversity and the domestication and utilization of wild wetland plants.

Background: Research was conducted to ascertain the impact of hormonal seed strengthening on seed health status under an accelerated ageing test in chickpea (Cicer arietinum L) at the state seed testing laboratory during the Rabi seasons of 2018-19 and 2019-20. Four replications of the Blotter test were performed CRD plan. As per continuous evaluation and observation, under accelerated ageing increased pathogens were observed with increased temperature and RH, the seeds treated with salicylic acid resulted with least pathogen infection while compared to other treatments. Methods: The current experiment was conducted in the state seed testing laboratory, Department of Genetics and Plant Breeding, SHUATS, Prayagraj, Uttar Pradesh, between the years of 2018 and 2020. 37 distinct treatment combinations were employed in the experiment. The seeds were placed in an accelerated ageing condition with high temperature and relative humidity. Hormonal seed strengthening is the activity of infusing PGRs into old seeds to make them fresh again with the help of PGRs (salicylic and giberellic acid) treatments into old seeds and increase the vigour index of seeds. Result: In this experiment chick pea seeds treated with combination of gibberellic acid and salicylic acid resulted in least infection of seed pathogens we can recommend these for maintaining seed health status.
