| Formation of mature cryptogamic crust typically requires decades free of disturbance. |
|
| This collection reflects the full gamut of its dedicatee's research interests in cryptogamic physiology and ecology at the extremes. |
|
| The cryptogamic organisms help to stabilize the soil, hold moisture, and provide protection for germination of the seeds of other plants. |
|
| Today the cryptogamic herbarium consists of 7000 lichens and 1500 bryophytes and continues to grow. |
|
| After this fact one need not be surprised at the diffusion of the far lighter and smaller sporules of cryptogamic plants. |
|
| From that point north, there was a startling, lifeless desolation, as if someone had decided to eradicate all signs of cryptogamic life. |
|
| Diacylglyceryltrimethylhomoserine is known to be an important component of cryptogamic plants, including bryophytes, but its physiological role is still uncertain. |
|
| He retired in 1990 after having been the garden's senior curator of cryptogamic botany and editor of its journals. |
|
| Winter wheat is subject to various cryptogamic diseases that are controlled by means of fungicidal treatments. |
|
| It provides a higher resistance to cryptogamic diseases caused by the deficiency of this micronutrient. |
|
| By the early XXth century, the ravages caused by insect pests and by cryptogamic diseases made the situation desperate. |
|
| Controlled vigour also reduces the vines' vulnerability to cryptogamic diseases. |
|
| It is, as a result, the sole actor authorized to implement protection measures against forest insect pests and cryptogamic diseases. |
|
| He prepares his spray gun to protect the vines against cryptogamic diseases such as mildew, oïdium or grey mould, but also against the dreaded insects: grape caterpillars, which are a significant pest. |
|
| The analysis of topoclimatological conditions and their spatial variability in the Grand Duchy of Luxembourg is employed for the development of warning systems concerning cryptogamic diseases in agro-systems. |
|
| Europhyt is the Community's rapid alert system for parasite, cryptogamic or virus problems in the production of agricultural, forestry and horticultural plants and seeds. |
|
| This project's objective is to design and prepare an integrated warning system for cryptogamic diseases affecting the winter wheat adapted to the agriculture in Luxembourg. |
|
| The Forest Act includes provisions for the control of destructive insects and cryptogamic diseases both in standing forests and in planting stock. |
|
| Grains attacked by wheat midge shall be considered damaged grains only when more than half the surface of the grain is coloured grey to black as a result of secondary cryptogamic attack. |
|
| Winter wheat, the country's most important crop after prairie spring wheat, is subject to various cryptogamic diseases including dry rot, caused by fungus. |
|
|
|
| Ecological studies of the colonisation process could add to our understanding of how spore reproducing lichens colonise surfaces already covered by cryptogamic swards. |
