Pour accroître sa biomasse, une plante a besoin d'eau. Cette dépendance fondamentale est toutefois plus ou moins poussée selon les cultures ou les environnements. Une culture à forte croissance peut donc produire plus de grains, à condition de gérer l'eau disponible pour atteindre la maturité, sous peine de subir de fortes pertes de rendements. La tolérance à la sécheresse résulte donc d'un fin équilibre entre maximiser l'utilisation de l'eau pour produire et garder suffisamment d'eau pour les stades clefs du développement [...]  2, record 1, French, - tol%C3%A9rance%20%C3%A0%20la%20s%C3%A9cheresse

Tolerance of plants to low water availability would involve physiological changes that allow the plant to survive the low water contents.... Cotton plants show some capacity to acclimate to low water conditions(tolerance) ;if they are watered daily, leaves wilt when they reach 90% relative water content(i. e. they lose 10% of their maximum water content). Genetically identical cotton grown under field conditions(drier) will wilt at 85% relative water content.

An allergist must first use allergy testing to confirm the patients sensitivities.

Tolerant cultivars can live in a compromise with the virus in that they suffer much less or no yield loss, despite being infected, compared to susceptible cultivars.

Walnut wilt is a noninfectious disease which causes the sudden wilt and death of many plant species. The problem occurs in the beds of sensitive plants growing near walnut trees... The cause is an active compound known as juglone produced by these trees. Juglone has been isolated from the roots, leaves, bark, and husks. The compound can also be found in a narrow zone in the soil surrounding the living roots. Because of this limited distribution of the toxin, the position of juglone producing roots underground is reflected in the pattern of wilting plants above ground... Affected plants wilt suddenly and often show a browning of the vascular tissues just under the outer layers of the main stem... Some plants with mild tolerance may show stunting, lack of flower development, and/or lack of vigor.  2, record 8, English, - walnut%20wilt

Threads are designated by standardized notes. Under the unified system, threads are specified by giving in order the nominal diameter, number of threads per inch, the initial letters such as UNC or UNF that identify the series, and class of thread (1A, 2A, and 3A or 1B, 2B and 3B). Threads are considered to be right-hand and single unless otherwise noted; therefore the specification for a left-hand thread must have the letters LH included.  2, record 22, English, - thread%20class

Degrés de précision des filets. On entend par ajustement des pièces de visserie, le jeu au montage entre la tige filetée et le taraudage. Les types d'ajustement pour les divers degrés de précision requis pour les filets normalisés "Unified" se divisent en trois catégories : 1A, 2A et 3A pour les filets extérieurs, et 1B, 2B et 3B pour les filets intérieurs. Ces catégories différent entre elles par l'importance du jeu et la tolérance.  1, record 22, French, - cat%C3%A9gorie%20de%20degr%C3%A9%20de%20pr%C3%A9cision%20des%20filets

The manufacturing tolerance and allowance permitted distinguishes one class of thread from another under the unified thread system. Because allowance is an intentional difference between correlated size dimensions of mating threads, and tolerance is the difference between limits of size, a thread class may be considered to control the looseness or tightness between mating threaded parts. The American National standard for unified and National screw thread provides classes 1A, 2A, and 3A for external threads, classes 1B, 2B, and 3B for internal threads, and classes 2 and 3 for both internal and external threads. Classes 1A and 1B are for ordnance and other special uses. Classes 2A and 2B are the recognized standards for the bulk of screw-thread work and for the normal production of threads on screws, bolts, and nuts. Classes 3A and 3B are for applications where smaller tolerances than those afforded by 2A and 2B are justified....  1, record 23, English, - 2B

A gold alloy of the same fineness as marked, or perhaps with a small tolerance such as. 003, instead of the half-karat or full-karat tolerances permitted by the National Stamping Act of 1906. Under the latter, for example, goods marked 14K(. 5833) could assay 13 1/2K(. 5625) ;or, if soldered, the entire article including solder could assay as low as 13K(. 5417).  1, record 24, English, - plumb%20gold
