Stage-dependent stoichiometric homeostasis and responses of nutrient resorption in Amaranthus mangostanus to nitrogen and phosphorus addition
Stoichiometric homeostasis is the ability of plants remaining their element composition relatively stable regardless of changes in nutrient availability, via various physiological mechanisms. Nutrient resorption is one of such key mechanisms, but whether and how nitrogen and phosphorus homeostasis and resorption in plants would change with growth-stages under variable nutrient supply was unclea...

Effects of mineral nutrient de®ciencies on leaf development, visual symptoms and shoot±root ratio of Spathiphyllum
Effects of de®ciencies in N, P, K, Ca, Mg, B and Fe on leaf development, visual symptoms and shoot±root dry weight ratio were studied in Spathiphyllum `Sensation' grown hydroponically. Leaf nutrient contents of treated plants were analyzed to con®rm suspected de®ciencies. Leaf number, leaf area and chlorophyll content were all signi®cantly reduced in the nitrogen-de®cient plants similar to plan...
متن کاملGenetic Control of Root Weight, Root Volume and Root to Shoot Weight Ratio in Peas
The genetic control of root weight, root volume and root to shoot weight ratio was studied in peas (Pisum sativum L.) at flowering. The four populations used were developed from crosses between lines and cultivars differing in size of the root systems. Plants of the F 1, F 2 , backcross and parental generations were evaluated in pots filled with soil: sand mixture, in a completely randomized de...
متن کاملthe influence of corpus luteum on follicular fluid composition from different size follicles and their relationship to serum concentrations in sanjabi ewes
the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
