Creator:: Martinez-Racines, Cesar P.
Abstract:: A nutrient solution technique developed for wheat was used to determine tolerance of rice cultivars to aluminum (Al) toxicity. Pre-germinated rice seed was placed on top of a screen and allowed to grow on the Al-free solution for 72-96 hours or until the primary root was 2-3 cms long. Seedlings...

Full Text:: . Aluminum also penetrated the epidermis and cortex. Cell desintegration and desorganization were noticed as

Creator:: Keim, Don Lee
Abstract:: Winter wheat cultivars (Triticum aestivum) were evaluated for their response to water stress and adaptability to a wide range of moisture limited environments. Grain yield was analyzed for ten cultivars at six locations across four years. Regression of the cultivar mean on the year-location mean was used as a measure...

Creator:: Lopez-Benitez, Alfonso
Abstract:: A technique previously designed to screen wheat cultivars and segregating populations for tolerance to Aluminum utilizing nutrient solutions in growth chambers was found to be efficient in differentiating among cultivars of wheat, rye, and triticale for tolerance to Al under greenhouse conditions. A 5°C increase in temperature, from 25°C to...
Resource Type:: Dissertation
Full Text:: , rye and triticale within the first three hours of Al treatment. Cell division decreased as exposure

Creator:: Conway, Michael Patrick
Abstract:: Laboratory studies were conducted under different temperature and moisture regimes to evaluate the effects of temperature and moisture on stand establishment and seedling characteristics associated with stand establishment. Percent stand and days to 25% emergence were used as indexes of stand establishment. Seedling characteristics analyzed were: shoot length, coleoptile length,...

Creator:: Yakar, Kamil
Abstract:: The purpose of this study was to determine the nature and amountof genetic variation and possible associations between winterhardinessand earliness in winter x spring wheat crosses.Four winter wheat cultivars selected for differences in earlinessand winterhardiness were crossed with a nonhardy, day length insensitivespring wheat cultivar. The following year, experiments containing...
