“…Nevertheless, both species showed low germination activity at high temperatures ranging from 15-25°C. This is in agreement with other studies that have also reported low germination rates in Mediterranean species such as Pistacia lentiscus, Phlomis italica and Urtica atrovirens subsp.bianorii [21,25,29]. This could be due to presence of dormancy mechanisms by which plants have adapted to unpredictable environments [43], including the Mediterranean climate.…”

“…Both Rhamnus species showed a longer dormancy period and T 50 under 15-25ºC than in the other treatments (5-15ºC and 10-20ºC). In contrast, a shorter dormancy period and T 50 have been reported for some Mediterranean species, such as Stipa tenacissima [30], Ceratonia siliqua [31], Diplotaxis ibicencis, Limonium magallufianum and Limonium gibertii at the same temperature regimes (5-15ºC, 10-20ºC and 15-25ºC) [25]. Differences between species in seed germination, dormancy period and T 50 are expected in Mediterranean ecosystems, since many of them show different types and degrees of dormancy [24].…”

“…alaternus and R. ludovici-salvatoris seed germination was tested at different temperatures. Previous studies have determined that seeds of both species germinate at high rates when subjected to alternate temperatures [25]. In addition, it was observed that light does not affect their seed germination [25].…”

“…Moreover, other Mediterranean species, such as Olea europaea [22], Pinus halepensis [23], and many others [see 20,24] have their optimum germination temperatures similar to those reported here. According to [25], the optimum germination temperature range in many endemic and non-endemic species of the Balearic Islands was found to be 10-20°C. Also, the plants from this region developed different germination strategies to ensure the highest survival of their seedlings.…”

Rhamnus alaternus and R. ludovici-salvatoris, two Mediterranean shrubs with different geographic distributions, have shown important differences in seedling recruitment capacity. The objectives of this work were to determine the ability of these species to germinate seeds under different temperature ranges, as well as the capacity of seedlings to emerge from different burial depths, in order to better understand their regeneration processes. Two different experiments were performed. In the first one, seed germination was studied in Petri dishes and in the dark at different temperature regimes: a) 5–15°C, b) 10–20°C and c) 15–25°C (12h/12h). In the second experiment, seedling emergence capacity from different burial depths (0.5, 2 and 5 cm) was tested. R. ludovici-salvatoris showed a significantly higher final germination rates, a lower dormancy period, and average time response at 10–20°C than at other temperature ranges, although differences were much greater when seeds were subjected to the 5–15°C temperature regime. By contrast, R. alaternus did not show significant differences between treatments (5–15°C and 10–20°C) in germination behavior. Seedling emergence of both species was lower and slower when seeds were buried at 5 cm. However, R. ludovici-salvatoris always showed a lower seedling emergence capacity than R. alaternus at any burial depth. The low ability of R. ludovici-salvatoris to germinate seeds and emerge between 5–15°C, even from shallow depths, is discussed in relation to its low regeneration capacity and declining geographic distribution.

In this work we investigated whether priming with auxin, cytokinin, gibberellin, abscisic acid and ethylene, alters the physiological responses of seeds of pigeon pea germinated under water and cadmium stress. Seeds treated with water or non-treated seeds were used as control. Although compared to non-treated seeds we found that the hormone treatments improve the germination of pigeon pea under cadmium stress, however, these treatments did not differ from water. However, we also observed a trend of tolerance to the effects of cadmium in the presence of ethylene, suggesting that the use of this hormone may be an efficient method to overcome seed germination under metal stress.

Beta Maritima

The traits of Beta maritima have been reviewed and summarized from a number of recent and classical publications dealing with the ecology, morphology, and whole-plant physiology of the species. Because few papers have been written only on sea beet, B. maritima , most information comes from cultivated forms of Beta vulgaris . A striking feature of B. maritima gleaned from this review is how variable and adaptive it is. The species is fairly plastic allowing it to live in many different environments. This capacity for adaptation has been correlated with its breeding system, which allows sea beet to rapidly change reproduction systems, fl owering time, life span, etc. according to the local environmental conditions. This is most evident to the observer in the differences between the Mediterranean populations with easy bolting, short life cycles, and those from the sea coasts of northwest Europe. This chapter provides the reader with a comprehensive overview of the plant and populations to answer the question: "What is B. maritima ?"
