In the present investigation the seeds of Pigeon pea (Cajanus cajan (L.) Millsp) were treated with different doses of gamma radiation (05KR, 10KR, 15KR, 20KR, 25KR, 30KR, 35KR, 40KR, 45KR, and 50KR) and concentration of Ethyl Methane Sulphonate (05mM, 10mM, 15mM, 20mM, 25mM, 30mM, 35mM, 40mM, 45mM, and 50mM) for studying seed germination, seedling height, (shoot and root), seedling injury, seedling vigour index, and seedling survival of plants at 30th day. The seed germination percentage was decreased with increased in the concentration/doses when compared to control. The LD50 (Lethal dose) value was determined based upon the seed germination percentage. The 50 percentage of seed germination and reduction was observed in 20KR of gamma rays and 25mM of EMS and it is considered as LD50 value for both the treatments. The decrease in seed germination was more prominent with gamma rays than that of EMS treatments. The seedling parameters of gamma rays and EMS treated seedlings were progressively decreased with increase dose/concentration in all mutagenic treatments when compared to control. The maximum seedling parameters were observed in 05KR of gamma rays and 05mM of EMS. Minimum seedling parameters were observed in 50mM of EMS and 50KR of gamma rays respectively.

Allelopathic Effects

In this study the allelopathic effects of Parthenium hysterophorus on seed germination and seedling growth in Cajanus cajan (Pigeon pea) was investigated. The dried powdered leaves of Parthenium hysterophorus were soaked in distilled water for 24 hours to obtain aqueous extract of leaves and sterilized seeds were treated with 2%, 4%, 6%,8%, and 10% concentration of extract in triplicate. The germinated seeds were counted every day to observe germination index (G.I.) and mean germination time (MGT). It has been found that germination index (GI) were significantly decreased and MGT were delayed to germinate with increasing concentration. It has been observed that seed germination percentage, root length, shoot length and seedling vigor index were reduced at >2% as compared to control. The 10 % aqueous extract showed completely inhibitory effect on seed germination. The present investigation showed that the leaves aqueous extract of Parthenium hysterophorus had inhibiting effects on seed germination and seedling growth in Cajanus cajan (Pigeon pea).

Pea Seed

Pigeon pea (Cajanus cajan cv. 38-Bushy) seeds were harvested at maturity and 1, 2 or 3 weeks after maturity (delayed harvests) from non sprayed plants or from plants sprayed with maneb, benomyl, or a combination of the two at four 1-week intervals beginning 110 days after planting. At each harvest date, the decrease in percentage germination and emergence and the increase in seed borne fungi was significantly less for seeds from benomyl-sprayed plants than from nonsprayed plants or those sprayed with maneb. The percentage seed germination in vitro and field emergence decreased and the percentage of internally seedborne fungi increased with each delay in harvest for all treatments. There were no significant differences in total internally seed borne fungi, germination in vitro, or field emergence between plants sprayed with maneb alone and the nontreated control. When harvested at maturity, plants of all treatments produced good quality seeds (over 85% germination).
