Hunter and Grant (1971) demonstrated that with some grass cultivars yield declined by approximately 2% for every 30.5 m increase in altitude, and that the development of flowering was delayed by 1.3 days per 30.5 m increase in altitude. 

Rule No. 2 If you have a turf lawn, it does not have to be the grasses you inherited Grass cultivars vary tremendously. Most often, however, we do not actually choose the kind of grasses we have in our lawn, either because we bought or rented the house with the current lawn, or because a new home was created with lawn grasses chosen by the developer (usually for reasons of cost and convenience. 

Since 1889, improved grass and cereal cultivars have been bred.41 It is difficult, and may be commercially impossible, to obtain viable seeds of cultivars required for studies extending over several years, as the cultivar may meanwhile have been replaced by another. For this reason, it may not be possible to re-examine the hemicelluloses of a cereal or grass cultivar studied earlier.
