Seed Water Content

Three visible indicators of seed water content were evaluated to determine the correct time to desiccate field pea. Assessment of the percentage of brown pods, using visual estimates or by counting, were equally effective indicators of seed water content. Counting "dry colored" seeds ("tan" for a yellow cotyledon cultivar; "blue-green" for a green cotyledon cultivar) was less effective. Key words: Field pea, Pisum sativum L., desiccation

Uniform imbibition and germination of field pea (Pisum sativum L.) seeds is very important for sprout production for human consumption. The imbibition and germination of 3 cultivars of field pea, Dunwa, Dundale, and Helena, each grown at Mullewa, Merredin, and Scaddan in the grainbelt of Western Australia, were investigated in laboratory experiments. The ability of field pea to germinate was affected by cultivar and the environment under which seed development occurred on the parent plant. Averaged over locations, germination of the cv. Dundale (82%) was lower than of Dunwa (93%) or Helena (95%). Germination of seeds ranged from 85% for those grown at Merredin to 91% at Scaddan and 94% at Mullewa. The effect of growing location on germination was most pronounced in cv. Dundale from Merredin where the largest number of hard seeds was observed. Initial seed water content was positively (r2 = 0.55*) correlated with germination across cultivars and sites. Small and large seeds within a seed lot with the same initial seed water content had a similar germination percentage. During imbibition, water entered the seed through the strophiole and this would be an appropriate place to look for a mechanism that affects imbibition. Careful selection of cultivar and favourable growing site should improve germination for the sprout producer.

Proximate And Mineral Composition

Field pea seeds from 10 cultivars grown at two locations in Manitoba in 1986 and 1987 were analyzed for proximate and mineral profiles. Cultivars differed significantly in their level of total protein, crude fat, ADF, and all minerals tested. However, differences were not extremely large and were comparable to European reports. Location-year also had a significant effect on the levels of total protein, ADF, and all minerals tested. In most cases, the warmest location-year produced relatively higher levels of minerals, ash, and total protein, and lower seed yield than the coolest location-year.

The use of fungicides for the control of ascochyta blight in field pea was investigated. Four fungicides were applied to the cultivars AC Tamor and Radley at two locations in Manitoba in 1993 and 1994. Fungicides were applied either once, twice, or three times at 10-d intervals, beginning at the initiation of flowering. Chlorothalonil and benomyl were effective m reducing the severity of ascochyta blight and increasing the yield and seed weight of field pea. The triple application of chlorothalonil resulted in a mean yield increase of 33% over that of the untreated control. Iprodione and propiconazole were relatively ineffective in controlling ascochyta blight. The percentage of seedborne ascochyta was not significantly affected by fungicide treatments. The severity of ascochyta blight was greater in 1993 that in 1994, resulting in greater benefits of chlorothalonil and benomyl applications in 1993.
