Plasticita funkčních charakteristik (traits) lučních rostlin / Functional trait plasticity in grassland plant speciesHAVLÍK, Tomáš January 2010 (has links)
Plant functional traits (plant height, aboveground biomass, R/S ratio, specific leaf area, leaf dry matter content, specific root length and arbuscular mycorrhizal infection) were measured for several grassland plant species growing under different soil fertility conditions in a greenhouse and a field experiments. Traits` response to nutrient addition and the differences in traits among species and between forbs and grasses were studied. Results from the greenhouse and the field experiment were compared.

An Analysis of Grain Corn Nutritional Supplements and Relative Maturity in MississippiWhittenton, Joseph Bryan 04 May 2018 (has links)
A review of available corn relative maturity groups in Mississippi shows a limited range of maturity groups in use. Research focusing on expanding the range of maturity groups was conducted in MS in 2015 and 2016. Along with expanded maturity groups, treatments of fertilizer (10-34-0), foliar zinc, and a plant hormone blend were studied to shorten the growing season. Four site years in MS were studied to determine optimal plant maturity group and treatment for length of season. The results showed decreased yield of 0.09-0.15 Mg ha-1 (1.5-2.3 bu ac-1) for each day of decreasing relative maturity in three of four site years. The addition of starter fertilizer increased vegetative growth stage, plant height V5 and V7, SPAD values at V5, and significantly decreases days to tassel and silking reproductive growth stages but did not affect yield.
