The seeds of different plants species has specificenvironment and requirements for germination.The seeds are variously influenced by differentenvironmental factors Such as light, moisture, pH,salinity or salt stress and seed burial depth.Temperature and light are considered the mostimportant environmental signals regulatinggermination, species distribution and ecologicalinteraction (Mayer and Poljakoff-Mayber, 1989;Bewley and Black, 1994; Baskin and Baskin, 1998).Some seeds germinate similarly in light anddarkness, while others do it more readily eitherunder light (Colbach et al., 2002) or darkconditions. The maximum temperature for mostspecies is between 30°C and 40°C. Salinity imposesserious environmental problems that affectgrassland cover and the availability of animal feedin arid and semiarid regions (El-kharbotly et al.,2003).
Seed size directly influences the germination time(Murali, 1997), germination percentage and seedlingvigour (Yanlong et al., 2007), which can indirectlydetermine plant distribution and abundance acrossdifferent habitats (Silveira et al., 2012). Biochemicalchange is a necessity foe the process of seedgermination. Greater amount of stored reserves allowa higher probability of seedling establishment at siteswith lower resource availability (Geritz, 1995).
Similar work was carried out by Shereen et al.(2011) rice experiments to study the effects of salinityon seed germination of six rice varieties differing insalt tolerance by treating them with 0, 50, 75, 100,200 mM NaCl solutions. Jamil et al.(2012) investigated the effects of salinity on seedgermination of three different rice genotypes andfound that the rice cultivars differed in theirgermination response to salt stress. Increase insalinity from 0 to 150 mM adversely affected the seedgermination percentage and significantly delayedseed germination. Bybordi (2010) reported that withthe increasing salt concentration the rate of seedgermination decreases in Brassica napus.
Seeds and the way of germination is an excellentanalogy for plant life on earth. Planting seeds is anoble work, because we dig, lay in the seeds,watering, fertilize and expect to harvest for ourfuture generation is known as sustainabledevelopment. Plantation not only business, hobbyetc., it's a kind of encouragement for our futuregeneration
