ABSTRACT: The present paper aims at studying the comparative analysis the effects of NaCl on the morphology and different pigment contents of widely cultivated crop Finger millet (Eleusine coracana L.) and Pigeon pea (Cajanus cajan L.) under laboratory conditions. Finger millet is an annual herbaceous plant which belongs to the family Poaceae widely grown as a cereal crop and Pigeon pea (variety -Manak) is a perennial, tropical legume grown mainly in India which belongs to the family Fabaceae. The effects of salinity appear to be dependent on the species and on the stage of the plant’s development (such as germination or vegetative growth). We have prepared 5mM, 10mM, 20mM, 40mM, 60mM,80mM, 100Mm, 200mM, 400mM concentrated solution by proportional dilution with distilled water for further treatments. A soil and sand bed in different bowls with sowing 30 number of seeds of ELeusine coracana and 10 number of seeds of Cajanus cajan separately at uniform distance in all the sets with test chemicals is prepared. We have selected 0mM(control),20mM,40mM,60mM for comparative analysis of both the genus. The emergence of radicle and plumule is considered as the index of germination. The seedlings are then exposed to light after germination. The following day, after the exposure of seeds to light, there is rapid elongation of radicle and plumule. On 10th day, 100% germination in control was observed. We also observed leaf emergence of seeds which are sown in different concentrations of NaCl, then we measured the length of shoot and root of both the genus. Fresh weight of root and shoot and dry weight of root and shoot (by keeping in Oven for 15 minutes) of both the genus was taken. On 10th day, we performed pigment analysis. There is an inverse relationship between the percentage of seed germination and concentration of NaCl i.e. with increase in concentration there is decrease in germination of seeds. The morphological studies also show that, at control the length of the shoot and root is maximum, but when the concentration of the stress increases, the root and shoot length, fresh and dry weight of root and shoot decreases due to more salinity. The pigment content of Eleusine coracana L. increases at 20mM but after that it decreases with increase in NaCl concentration. In Cajanus cajan L. pigment content decreases with increase in NaCl concentration. The effect of NaCl (salinity) stress is found to be more in Cajanus cajan L. than in Eleusine c oracana L.
