Clubroot in canola is caused by Plasmodiophora brassicae, a parasite that infects the roots of host plants and produces club-shaped galls that restrict the flow of water and nutrients. Plasmodiophora brassicae is an obligate parasite, meaning it cannot survive without a living host. Additional information is available from the Alberta Agriculture and Rural Development website....
A healthy-looking pulse plant in the field is not necessarily a reflection of healthy nitrogen fixation underground. Localized soil environments, particularly those with variations in soil nitrogen, can lead to vigorous growth that can hide any nodulation problems. A plant’s potential to fix nitrogen can be evaluated by assessing nodulation and plant growth characteristics. It means the only way to see if a rhizobia-based inoculantis helping the crop properly fix nitrogen is to dig plants up and examine the roots. PDF: Pulse Crop Nodulation Guide.pdf...
What is a vigour test? A vigour test reveals a seed lot’s ability to withstand a variety of different stress factors. Vigour tests are designed to mimic poor seeding conditions to find out how the seed lot will perform under stress. It’s the exact opposite of a germination test, where seed is grown under optimum conditions....
What are “The 3 Critical Seed Tests”? A germination test is an integral part of a seed quality regime and is vital for assessing seed viability. Beyond germination, we at 20/20 Seed Labs Inc. consider the 3 critical seed tests to be a vigour test, a thousand kernel weight test and a disease diagnostic profile to assess the range of seed borne diseases that may be present on the seed....
A germination test determines the maximum germination potential, or viability, of the seed. Why do a Germination Test? The germination rate of a particular seed lot is a key indicator as to how that seed will perform in the field....
