“…Having diverse potential applications, SMP not only increases the germination performance of seeds, but also provide a delivery system for selective fungicides and bio-control organisms to control various soil-borne pathogens (Harman and Taylor, 1988). Moreover, for improving seed emergence SMP could be used as a pre-sowing seed treatment when sown in cold soils especially for the plants sensitive to cool temperature (Marsh, 1993). Priming could allow greater membrane integrity in the embryo as a result of which the developing seedlings reduce ion leakage through the membranes.…”

The objective of present study was to evaluate the response of the mung bean seeds of 'Sonali B1' variety primed with chitosan in four different concentrations (0, 0.1%, 0.2% and 0.5%) under salinity stress of five different concentrations (i.e., 0, 4, 6, 8 and 12 dS*mm-1) and halotolerance pattern by applying Celite as matrix at three different moisture levels (5%, 10% and 20%). Improved germination percentage, germination index, mean germination time, coefficient of velocity of germination along with root and shoot length was observed comparing with control. Germination stress tolerance index (GSI), plant height stress tolerance index (PHSI) and root length stress tolerance index (RLSI) were used to evaluate the tolerance of the mung bean seeds against salinity stress induced by chitosan. Results of GSI, PHSI, RLSI showing noteworthy inhibitory effect of salinity stress in control set was significantly less pronounced in chitosan treated seedlings. Chitosan can remarkably alleviate the detrimental effect of salinity up to the level of 6 dS*m-1 , beyond which no improvement was noticed. In conclusion present investigation revealed that chitosan is an ideal elicitor for enhancing the speed of germination and seedling invigoration that synchronize with emergence of radicle and salinity stress tolerance.

“…High moisture content usually leads to seed dormancy. Marsh (1993) The virus produces typical vein yellowing and thickening of leaves forming a network of veins and veinlets in the infected leaves. In the beginning, the leaves exhibit only yellow colored veins but under severe infection, the leaves become completely chlorotic and turn yellow.…”

This paper provides detailed information specifically the botany, history, and current statistical report on okra as well as how it is cultivated. Major biotic and abiotic stress factors impeding the production of okra and the sustainability aspect in the production of the crop are discussed. Many reasons for poor growth and development, low yield of okra as well as seed dormancy or okra plant death are mentioned. These include poor quality of seed and some biotic stresses particularly yellow vein mosaic virus (YVMV) and abiotic stresses such as salinity, drought, various water stresses and high moisture content. However, okra as a tropical and subtropical crop is drought-resistant, thus does well under drought conditions. Notwithstanding, high moisture content, salinity, and the yellow vein mosaic virus disease are the major factors affecting the crop. These conditions especially the yellow vein mosaic virus disease reduce okra yield to about 94% depending on the time of infestation after germination. To control the mosaic virus disease, very limited success has been achieved by chemical methods (including the application of neem oil, Acetamiprid, Imidacloprid and Trizophos), which also are not permanent since some resistant cultivar become susceptible with time. Therefore, advance breeding and development of host resistance to viruses and measures to combat salinity are the important strategies against these impeding conditions.

“…Sionit et al, (1981) reported seed germination for okra (Clemson spineless) at 16/11, 20/14 and 23/17 °C day/night temperature, with the lowest temperature delayed the emergence. Lurline Marsh (1993) studied the effect of moisture content on the emergence and development of okra seeds and found that high moisture decreased the emergence of okra seeds. Anderson (2012) found that selection of a hybrid that germinates early under favorable temperature and then weeds would not offer competition, is the most efficient method for achieving good establishment.…”
