Made of plastic, the low tunnels are placed over the top of the crop, making it as much as 8 to 10 degrees warmer. In low tunnels, plastic covers are supported above the crop by wire hoops. The width of the hoop at the base is 24 to 36 inches, and the height at the hoop's apex is 14 to 18 inches. The low tunnels make it possible for crops to be in temperatures 12 to 15 degrees warmer than outside at night...  2, record 1, English, - low%20tunnel

[Le] tunnel plastique [est une] enceinte réalisée à partir d'un film plastique souple, transparent à la lumière naturelle, permettant -- au moins temporairement -- de modifier l'environnement climatique de la culture pratiquée à son abri pour en améliorer la précocité ou en assurer la protection contre les basses températures (mais non contre le gel). Les dimensions peuvent en être très diverses : - tunnels bas, hauteur 0,5 mètre, largeurs 0,5 à 1,0 mètre, - abris-serres, hauteur 1,5 à 3,5 mètres, largeur 3 à 9 mètres.  1, record 1, French, - tunnel%20bas

Kniffin Training. This is the most popular training system in the eastern regions. The photograph in Plate VIII shows a young vine trained to the four-cane Kniffin form, just after it has been pruned. The vine consists of a trunk about four feet long, to reach to the top wire of a four-foot trellis. Near the head may be seen two canes and two spurs-the canes to produce the season's crop, and the spurs to produce the renewal wood for the subsequent season. At a point on the trunk near the lower wire, two canes with their spurs are also left. These lower canes are pruned somewhat shorter than the top canes, because the growth of their shoots tends to be less vigorous. Shoots from the eyes of the four canes droop downward(a normal way of growth for many of the native hybrids) forming a mantle of foliage for the fruit.(A Wine-Grower's Guide, 1965, p. 121).  1, record 2, English, - Kniffin

Dans les régions viticoles du nord de l'Amérique : New York, Ontario, Colombie Britannique, État de Washington, etc... le système Kniffen a été employé pendant longtemps, et l'est encore. Cette méthode procure un haut tronc permanent sur lequel 4, mais maintenant plutôt 6 sarments, que l'on appelle bras (arms) étagés de chaque côté, sont renouvelés annuellement. (La culture de la vigne au Québec, 1986, p. 99).  1, record 2, French, - Kniffen
