Pea Root Rot

The ability of field soils to suppress pea root rot caused by Aphanomyces euteiches was assessed in field soil samples in a greenhouse bioassay and in field experiments sown with pea in monoculture for four years. In the bioassay, an inoculum of oospores in talcum powder was added to the test soils 1 week prior to sowing of pea seeds. The rate of infection was assessed 4 weeks after sowing. The field experiments were placed in six localities with varying degrees of soil suppressiveness to pea root rot and the pea yield and number of oospores of A. euteiches in root tissue were measured each year. A large variation in disease suppression was found in 24 arbitrarily chosen soils, sampled in the vining pea growing area in southern Sweden, and some soils were found to be strongly disease suppressive. The pea root rot development was also clearly different between the field experiments, depending on the soil. In an experiment on a soil showing low disease suppressiveness in the greenhouse bioassay, the crop failed in the second year, the number of oospores in root tissue increased rapidly over time, and no yield at all could be taken the fourth year. In contrast, on a soil with a high disease suppressiveness in the bioassay, the pea monoculture led to a slow build-up of oospores in root tissue and a steady high yield of 5,300 kg/ha the fourth year.

Sainfoin (Fabaceae) is one of the most critical animal forage crops. However, the tolerance of sainfoin is low against to salinity. This study aims to investigate biochemical responses of the shoot and root tissue of sainfoin seedlings to moderate salt stress under in vitro conditions. For this aim, the seed of sainfoin were sown MS medium containing 100 mM NaCl. Antioxidant enzymes (CAT, SOD, APX, and GR), proline and malondialdehyde (MDA) contents were measured in shoot and root tissue of 35-day-old seedlings of sainfoin. A significantly higher constitutive catalase (CAT) and superoxide dismutase (SOD) activity was observed in shoot tissues when compared to root tissues. Overall, salt stress caused significant more enhancement in the activity of antioxidant enzymes (CAT, SOD, APX, and GR) in shoot tissues than root tissue. On the other hand, among the antioxidant enzymes, SOD seems to be more active in both tissues of sainfoin. Interestingly, the activity of GR reduced in both tissue under salt stress. The content of proline and MDA has been increased under salt stress and this increase has been more in the root tissue. This study has revealed biochemical responses to salt stress in different organs of sainfoin.

Does salinity induce early ageing of pea root tissue?
