Tabebuia rosea is a native tropical tree species with high potential of implementation in commercial reforestation and ecological restoration. We studied the effect suppression essential nutrients on growth T. nursery. The design was completely randomized ten treatments: one that included full fertilization, another without others N, P, K, Ca, Mg, S, B, cationic microelements. Biometric variabl...

Weed Risk Assessment (WRA) methods for evaluating invasiveness in plants have evolved rapidly in the last two decades. Many WRA tools exist, but none were specifically designed to screen ornamental plants prior to being released into the environment. To be accepted as a tool to evaluate ornamental plants for the nursery industry, it is critical that a WRA tool accurately predicts non-invasivene...

Reforestation and restoration using nursery-produced seedlings is often the most reliable way to ensure successful establishment rapid growth of native plants. Plant success—that is, ability for plant develop within a set period time with minimal further interventions needed—depends greatly on decisions made prior planting, yet nursery-grown plants are produced independently considering range s...

Nutrient loading can improve the growth and nutrient content of nursery-grown Betula alnoides Buch.-Ham. ex D. Don, but it is unknown whether enhances uptake after transplanting. Plants were grown with three treatments (N100, N200, N400; 100, 200, 400 mg N per plant as 15N-urea) in nursery containers then transplanted into plastic pots, or without controlled-release fertilizer (F0 F10, 0 10 g p...

Calonectria (Ca.) species and their Cylindrocladium (Cy.) anamorphs are well-known pathogens of forest nursery plants in subtropical and tropical areas of the world. An investigation of the mortality of rooted Pinus cuttings in a commercial forest nursery in Colombia led to the isolation of two Cylindrocladium anamorphs of Calonectria species. The aim of this study was to identify these species...

Phytophthora ramorum is infecting plants in Oregon forests and nurseries. In this study, we analyzed the population structure of the P. ramorum in Oregon from 2001 to 2004 using microsatellites. The P. ramorum population in Oregon is characterized by low genetic diversity, significant genetic differences between nursery and forest populations, and no evidence of sexual recombination. The forest...

Developing alfalfa varieties with tolerance to salinity requires a multi-prong research approach. Because of the complexity of the plant by environment interaction a combination of laboratory, field and greenhouse selection techniques is most effective in addressing this complicated trait. At Forage Genetics our breeding strategy for salinity tolerance includes high throughput laboratory and gr...

Citrus bacterial spot (CBS), caused by Xanthomonas campestris pv. citrumelo, produces unsightly blemishes on leaves and stems of nursery plants that may affect their mar ket value. In simulated nurseries, Swingle citrumelo and 'Ruby red' grapefruit infected with X. c. citrumelo were treated with combinations of defoliation and sprays of copper ammonium complex (CAC) to control CBS. Also, Swingl...
