Genetic variation in adaptive traits and seed transfer zones for Pseudoroegneria spicata (bluebunch wheatgrass) in the northwestern United States
A genecological approach was used to explore genetic variation in adaptive traits in Pseudoroegneria spicata, a key restoration grass, in the intermountain western United States. Common garden experiments were established at three contrasting sites with seedlings from two maternal parents from each of 114 populations along with five commercial releases commonly used in restoration. Traits assoc...
متن کاملDrought stress, growth and nonstructural carbohydrate dynamics of pine trees in a semi-arid forest.
In trees exposed to prolonged drought, both carbon uptake (C source) and growth (C sink) typically decrease. This correlation raises two important questions: (i) to what degree is tree growth limited by C availability; and (ii) is growth limited by concurrent C storage (e.g., as nonstructural carbohydrates, NSC)? To test the relationships between drought, growth and C reserves, we monitored the...
متن کاملResponse of Russian brome, crested wheatgrass and tall wheatgrass to annual precipitation and grazing management in a semi-arid area
Three grass species, Agropyron desertorum (Agde) and Agropyron elongatum (Agel) and recently, Bromus tomentellus (Brto) are mainly used for range improvement as mixed seeding in semi-arid areas of Iran. Because there is little information about management of these grasses, this study was conducted at the Sisab Research Station in northern Iran to evaluate their responses to grazing management a...
متن کاملEffects of Boron Deficiency on Leaf Photosynthesis and Nonstructural Carbohydrate Concentrations of Cotton during Early Growth
In crop growth and development, boron (B) is an essential trace element. Boron deficiency is common in highly leached, acidic sandy soils of cotton (Gossypium hirsutum L.) growing regions in the world. Boron is particularly important in pollen germination and pollen tube growth resulting in successful fruit setting. Therefore, B deficiency during flowering and fruiting may significantly reduce ...
متن کاملNonstructural carbohydrate supplementation of yearling heifers and range beef cows.
A digestion study with 28 yearling heifers (428 +/- 9.9 kg; Exp. 1) and a 2-yr winter grazing trial with 60 crossbred cows (552 +/- 6.9 kg; Exp. 2) were used to determine the effects of level of nonstructural carbohydrate (NSC) supplementation on intake and digestibility of low-quality forage. Treatments were as follows: 1) control, no supplement; 2) 0.32 kg of NSC (1.8 kg/d of soybean hulls an...
