- Abstract:
- ... Despite good resistance to acid-soil stresses, white clover (Trifolium repens L.) is not found on some acid soils. Our objectives were to develop a large-leafed white clover with acid-soil resistance, to relate seedling Al to mature plant acid-soil resistance, and to validate our soil-on-agar procedure. We used a two-stage selection procedure. In Stage 1 we used the soil-on-agar technique to selec ...

- Abstract:
- ... Establishment of small-seeded legumes on strongly acid soils can be even more difficult than maintaining those stands once established. Our objectives were to use a soil-based procedure for characterization of acid-soil resistance of small-seeded forage-legumes and to determine the validity of primary root growth and specifically the soil-on-agar technique, using germplasm that varied widely in se ...

- Abstract:
- ... In emerging Panicoid grass seedlings, elongation of the subcoleoptile internode (SCI) stops shortly after the coleoptile tip receives a red light stimulus. This results in final placement of the crown node (CN) near the soil surface. Because adventitious roots originate from the CN, excessive elongation of the SCI places the CN above the soil surface, adversely impacting seedling establishment. A ...

- Abstract:
- ... Apomictic plant breeding is being practiced in several turf and forage grasses. Variation released during apomictic breeding has been discussed, but few reports have quantified this variation. Our objectives were to characterize variation among lovegrass, Eragrostis curvula (Schrad.) Nees, hybrids and their parents, compare parents and hybrids, and determine interrelationships among the characteri ...

Apomictic lovegrass hybrids, developed from introductions with higher forage quality, need to be evaluated in multiple environments to determine their potential. Studies were to be established in Argentina the same year seed was produced in ...

To select for improved acid-soil resistance we needed an effective and efficient soil-based procedure. Our objective was to develop a simple, rapid, nondestructive technique that could be used to evaluate acid-soil resistance of clover accessions. Our technique uses a thin layer of a ...

- Abstract:
- ... Epicuticular wax restricts water loss across the cuticle of plant leaves and is considered to aid in drought resistance. This conserving effect is roughly proportional to the amount of wax present. We measured wax levels, water loss, and leaf width and rolling characteristics of 19 lovegrasses, Eragrostis curvula (Schrad.) Nees, to determine if variation existed for these characteristics and the r ...

This study was conducted to locate sexual germplasm and describe the reproductive process in lehmann lovegrass. Purported diploid germplasm was grown in pots in a greenhouse. Chromosome number was determined and embryo sac development was stud ...

This study was undertaken to determine the cytology, method of reproduction, and fertility of three biotypes and the forage yield and quality of two of them. Two biotypes, Torres and Uruguaiana, were introduced from s ...

Recent studies have shown that certain plants of this species are facultative apomicts.
