“…These positive effects are probably due to the stimulatory effects of priming on the early stages of germination process by mediation of cell division in germinating seeds (Szabolcs, 1994;Sivriteps et al, 2003). There are several reports that seed priming can homogenize seed germination in a short period of time (Zhu, 2002;Khajeh-Hosseini et al, 2003). The present study also demonstrated that plant height recorded in plants derived from primed seeds were significantly different from plants derived from non-primed treatments when exposed to different salinity levels.…”

Salinity is one of the biggest limiting factors for agriculture in semi-arid areas of the world. For this reason, an experiment was conducted to study the effect of seed priming with NaCl and CaCl 2 on growth and yield responses of Tunisian coriander cultivar exposed to five levels of salinity (0, 2, 4, 6, 8 g l -1 ). Seeds of coriander were primed with aerated solutions of 0.13 M NaCl and CaCl 2 for 24 h. Results indicated that with increasing salinity, emergence traits (total emergence, mean emergence time), growth parameters (plant height, shoot fresh and dry weight) and mineral contents (K + and Ca 2+ ) decreased, but to a less degree in primed seeds. In all of the salinity levels, primed seeds possessed higher emergence and growth rate than control. However, further studies are needed to highlight the effect of seed priming on yield and oil content of coriander under salt stress.Key words: Coriander, salinity, seed priming, emergence, growth, mineral content IZVLEČEK VPLIV PRETRETIRANJA SEMEN KORIANDRA (Coriandrum sativum L.) S SOLNIMI RAZTOPINAMI NA VZNIK IN RAST V RAZMERAH SOLNEGA STRESASlanost je eden izmed največjih omejevalnih dejavnikov kmetijstva v polsušnih območjih sveta. V ta namen je bil izveden poskus za preučevanje učinkov predtretiranja semen z NaCl in CaCl 2 sorte tunizijskega koriandra na parametre rasti in pridelka, ki je bila izpostavljena petim stopnjam slanosti (0, 2, 4, 6, 8 g l -1 ). Semena koriandra so bila tretirana s prezračeno raztopino 0.13 M NaCl in CaCl 2 za 24 h. Izsledki so pokazali, da so z naraščajočo slanostjo parametri vznika (totalni vznik, poprečni čas vznika), rasti (višina rastlin, sveža in suha masa poganjkov) in vsebnosti hranil (K + in Ca 2+ ) upadli, vendar manj pri predhodno tretiranih semenih. Predhodno tretirana semena so imela pri vseh stopnjah slanosti boljši vznik in večjo rast kot kontrola. Za preučitev učinka predtretiranja s solmi na pridelek in vsebnost olj koriandra v razmerah solnega stresa so potrebne še nadaljne raziskave.

“…Salt stress substantially reduces and delays germination in maize (Farsiani and Ghobadi 2009) due to salinity-induced osmotic stress and toxic effects of sodium and chloride ions on germinating seeds (Hasegawa et al 2000;Khaje-Hosseini et al 2003). Seed priming has the potential to improve maize germination under saline conditions.…”

Maize is grown under a wide spectrum of soil and climatic conditions. Maize is moderately sensitive to salt stress; therefore, soil salinity is a serious threat to its production worldwide. Understanding maize response to salt stress and resistance mechanisms and overviewing management options may help to devise strategies for improved maize performance in saline environments. Here, we reviewed the effects, resistance mechanisms, and management of salt stress in maize. Our main conclusions are as follows: (1) germination and stand establishment are more sensitive to salt stress than later developmental stages. (2) High rhizosphere sodium and chloride decrease plant uptake of nitrogen, potassium, calcium, magnesium, and iron. (3) Reduced grain weight and number are responsible for low grain yield in maize under salt stress. Sink limitations and reduced acid invertase activity in developing grains is responsible for poor kernel setting under salt stress. (4) Exclusion of excessive sodium or its compartmentation into vacuoles is an important adaptive strategy for maize under salt stress. (5) Apoplastic acidification, required for cell wall extensibility, is an important indicator of salt resistance, but not essential for better maize growth under salt stress. (6) Upregulation of antioxidant defense genes and β-expansin proteins is important for salt resistance in maize. (7) Arbuscular mycorrhizal fungi improve salt resistance in maize due to better plant nutrient availability. (8) Seed priming is an effective approach for improving maize germination under salt stress. (9) Integration of screening, breeding and ion homeostasis mechanisms into a functional paradigm for the whole plant may help to enhance salt resistance in maize.

“…Nesta fase a semente exige um grande volume de água para iniciar o processo de embebição e estimular as reações bioquímicas que resultarão na formação das plântulas (TAIZ; ZEIGER, 2004), sendo este um dos fatores mais importantes que influenciam a germinação (KHAJEH-HOSSEINI et al, 2003). A escassez de chuvas neste período é favorável à colheita da soja na maior parte do Estado de Mato Grosso, no entanto, pode ser prejudicial para estabelecimento de estandes uniformes de milho, já que a semeadura deve ser realizada logo após a colheita da soja para evitar déficit hídrico nos estádios subsequentes.…”

RESUMOFatores climáticos são os principais causadores de flutuações no rendimento de grãos das culturas agrícolas, sobretudo no cultivo do milho segunda época, sendo fundamental a escolha da melhor época de semeadura e cultivar que mais se adapta a região. Dessa forma, objetivou-se testar o desenvolvimento e a produtividade de híbridos de milho em diferentes épocas de semeadura, em função das variáveis climáticas, tais como, temperatura e precipitação no município de Tangará da Serra, MT. O trabalho foi desenvolvido no campo experimental da UNEMAT, localizado geograficamente a 14º39' S e 57º25' O, com altitude média de 321,5 metros, em delineamento blocos casualizados, sendo os tratamentos constituídos por 5 híbridos e três épocas de semeadura, com quatro repetições. Verificou-se que a temperatura média se manteve dentro da faixa ideal em todo o ciclo da cultura. Entretanto, foi possível verificar a interferência negativa da precipitação irregular e insuficiente no florescimento e enchimento de grãos, que ocasionou déficit hídrico no solo e redução de produtividade. A altura de plantas, altura de inserção da espiga, diâmetro da espiga, comprimento da espiga e número de fileiras apresentaram diferença significativas entre os híbridos analisados, mas não influenciaram diretamente sobre a massa de 1000 grãos e produtividade. Com o avanço da época de semeadura, ocorre diminuição de todos componentes de produção e também da produtividade de grãos, sendo as maiores produtividades observadas nas épocasm1 e 2, com 5.297,22 e 5.133,74 kg ha -1 , respectivamente.
