LUCERNE CULTURE
ESTABLISHING NEW STANDS
Eecently an unsatisfactory strike of lucerne inocullated with a six-year-old culture has demonstrated the necessity of using fresh cultures when establishing new stands, states the " New Zealand Journal of Agriculture." A satisfactory culture should contain a maximum number of bacteria capable of forming nodules. It is known that bacterial cultures decrease in viability on artificial media; and it is also known that these bacteria stored on such a medium lose their power of infecting the host. It is' evident that old cultures must be greatly weakened both in numbers and their ability to form nodules. In the mycological laboratory of the Plant Research Station at Palmerston North it is the practice to restrict to a minimum the period under artificial conditions; the period from isolation from selected nodules to inoculation of the seed rarely exceeds three weeks. By these precautions the farmer is assured that the cultures supplied by the Department of Agriculture will give a maximum inoculation of the crop.
