“… Farooq et al (2008) and Khan et al (2012) reported beneficial effects of seed-priming in terms of better germination, more vigorous growth, early flowering and higher yield. In the present study, we observed significant retardation in the growth and development of contrasting rice genotypes under drought-stress which is in agreement with the observations reported earlier ( Afzal et al, 2006 ; Bhargava et al, 2015 ). It may be due to the reduced water potential, increased reactive oxidant potential and membrane damages.…”

Rice (Oryza sativa L.) is one of the major grain cereals of the Indian subcontinent which face water-deficit stress for their cultivation. Seed-priming has been reported to be a useful approach to complement stress responses in plants. In the present study, seed-priming with hormonal or chemical elicitor [viz. methyl jasmonate (MJ), salicylic acid (SA), paclobutrazol (PB)] showed significant increase in total phenolic content, antioxidant activity and expression of Rice Drought-responsive (RD1 and RD2) genes (of AP2/ERF family) in contrasting rice genotypes (Nagina-22, drought-tolerant and Pusa Sugandh-5, drought-sensitive) under drought stress. However, decrease in lipid peroxidation and protein oxidation was observed not only under the stress but also under control condition in the plants raised from primed seeds. Expression analyses of RD1 and RD2 genes showed upregulated expression in the plants raised from primed seeds under drought stress. Moreover, the RD2 gene and the drought-sensitive genotype showed better response than that of the RD1 gene and the drought-tolerant genotype in combating the effects of drought stress. Among the elicitors, MJ was found to be the most effective for seed-priming, followed by PB and SA. Growth and development of the plants raised from primed seeds were found to be better under control and drought stress conditions compared to that of the plants raised from unprimed seeds under the stress. The present study suggests that seed-priming could be one of the useful approaches to be explored toward the development of simple, cost-effective and farmer-friendly technology to enhance rice yield in rainfed areas.

“…Antirrhinum majus L. (Plantaginaceae) is a hermaphroditic, self‐incompatible, short‐lived perennial species producing inflorescences and small seeds dispersed by gravity a few metres apart from the plant (Andalo et al, 2010 ; Khimoun et al, 2011 ). It is known to have a poor and slow rate of seed germination (Bhargava et al, 2015 ), with seeds germinating better on the surface of soil and at mild temperature (around 20°C, Kang & Choi, 2006 ).…”

“…Multiple observations in southern France of snapdragon seedlings early in spring at low elevation and later in the summer at high elevation in the Pyrenees support this consensus adaptive scenario. A unique seasonal peak of germination across years is documented in snapdragon cultivated plants (Bhargava et al, 2015 ; Kang & Choi, 2006 ). Furthermore, snapdragon plants exhibit a strong phenotypic plasticity in response to shade and its suite of covarying environmental factors, for example temperature, water availability (Gourcilleau et al, 2019 ; Mouginot et al, 2021 ; Mousset et al, 2021 ), including in their seed germination that is delayed up to several days or prevented by shade (Kang & Choi, 2006 ; Smith & Whitelam, 1997 ).…”

“…Germination sensitiveness to light is common in small‐seeded species (Baskin & Baskin, 2014 ). In terms of ecological significance, this might be explained by seed dispersal, with snapdragon seeds dispersed only on or near soil surface but not buried in the soil (Bhargava et al, 2015 ; Kang & Choi, 2006 ; Leishman et al, 2000 ; Milberg et al, 2000 ).…”

Non‐reproducible signals of adaptation to elevation between open and understorey microhabitats in snapdragon plants

Our ability to investigate adaptation presents a number of complications resulting from the multidimensional complexity of the environment. Awareness on this issue was recently raised in the scientific literature (Anderson & Wadgymar, 2020;Chevin & Lande, 2015;Westneat et al., 2019). From a practical perspective, the adaptation or maladaptation of populations to their habitat is generally inferred on the basis of their genetic differentiation for fitness-related traits (Hereford, 2009;Leimu &

“…Seed priming is a process of controlled hydration of seeds, which causes the activation of essential metabolic events for germination. Therefore, primed seeds usually lead to greater uniformity and speed of germination (Bhargava, Gupta, Dhiman, & Sharma, 2015; Jaddoa & Najem, 2017; Yari, Aghaalikani, & Khazaei, 2010).…”

Seed response to priming with 24-epibrassinolide (24-EpiBL) has been studied to investigate the effects on speed of germination, often leading to improved stand establishment. However, knowledge about the response of primed seeds treated with 24-EpiBL during storage remains insufficient. This research was performed to verify the effects of bell pepper seed priming (Capsicum annuum L.) with 24-EpiBL after storage. Two cultivars (AF-6 and AF-7) were used, represented respectively by three and four seed lots of different physiological potential. All lots were stored for 0, 3, 6, 9, and 12 mo after priming with 24-EpiBL. Seeds were evaluated for germination and vigor (germination first count; saturated salt accelerated aging, and using the Seed Vigor Imaging System); unprimed seeds represented the control. Priming with 24-EpiBL promoted positive effects on germination speed, seed tolerance to heat stress, and initial development of seedlings with responses being more evident in lower vigor seed lots. The beneficial effects of priming with 24-EpiBL in bell pepper seeds is maintained after storage, but may gradually decrease after longer storage period.
