Bolivian Begonia are among the most poorly studied of American begonias. We provide here a checklist and key to the Bolivian Begonia flora, which currently includes ten sections, 43 species, three subspecies and three varieties. We also fully discuss the nomenclature and typification of all Bolivian Begonia species and designate 16 lectotypes. We describe and provide an illustration of one new species and provide emended descriptions for eight species. We have assessed six species for extinction risk under IUCN Red List criteria and provide four new synonyms. We compare our checklist with prev

Abstract:

Begonia is very popular as a foliage plant and some begonia species grow up in pots. Begonia serratipetala and Begonia muricata are Indonesian begonia species that are well suited as indoor potted plants because of their leaf color and shape. In addition, the Bali Botanical Garden's landscape nursery would like to use these begonias for decoration in all buildings. However, it still needs to be studied how long the shelf life of the two begonias is in indoor environments in the highlands without air conditioning (AC). The aim of this study was to investigate the indoor shelf life of B. serrati

Abstract:

Impatiens necrotic spot virus (INSV) and Tomato spotted wilt virus (TSWV) are the most serious viral pathogens in the production of ornamental plants in Europe and North America (1). During a survey for the presence of tospoviruses in July 2012, potted begonia hybrids (Begonia × tuberhybrida Voss) exhibiting foliar chlorotic rings and zonal spots accompanied by leaf necrosis and distortion, were observed in a greenhouse in the vicinity of Banja Luka (Bosnia and Herzegovina). Leaf samples collected from 12 symptomatic plants were analyzed for the presence of INSV and TSWV by commercial double-a

Abstract:

During 2003, 10% of the Hiemalis begonias (Begonia × hiemalis Fotsch) developed wilt symptoms in a commercial greenhouse in Connecticut. Foliage turned a dull green, and stems developed a dark watersoaked discoloration near the soil line and had vascular discoloration. Stems, petioles, and leaves collapsed and became covered with sporodochia of a Fusarium spp. Single conidia were isolated from sporodochia and cultured on carnation leaf agar (CLA) and potato dextrose agar for 10 days. Isolates resembled Fusarium oxysporum, but the profuse sporulation with minimal aerial mycelium and the rare oc

Abstract:

The quantity and quality of available water in the Southeastern United States continues to decline as demands on limited resources increase. Growers will soon be forced to comply with legal limitations on water consumption and limits on nutrient runoff from their operations. A lack of information on standard growing practices using alternative irrigation systems such as ebb and flow is hindering their acceptance and implementation. We are currently conducting a series of experiments to establish basic growing guidelines for the use of ebb and flow in the greenhouse in bedding plant production.

Abstract:

Begonia semperflorens, or wax begonias, are popular ornamental plants often challenged by heat and high light stress in subtropical and tropical regions. This study examined the responses of two stress-tolerant genotypes (FB08-059 and OPGC 5104) and two stress-susceptible genotypes (Cocktail Vodka and Sprint White) under elevated temperature and light conditions. The results revealed significant genotype-dependent differences in stress responses. Stress-tolerant genotypes demonstrated distinct adaptive traits, including thicker cuticles, acute leaf folding, and elevated anthocyanin accumulatio

Abstract:

Impatiens necrotic spot virus (INSV) is a member of the genus Tospovirus, and one of the prevalent viruses infecting ornamental plants, including begonia. Since the late 1980s, it has caused dramatic and unusual diseases on many flower crops, leading to considerable economic losses to the greenhouse floriculture industry (1). The western flower thrips, Frankliniella occidentalis (Pergande), is the only species currently known to vector INSV (1). In spring 2012, stunted plant growth and necrotic spots were observed on leaves of all Hiemalis begonias (Begonia × hiemalis Fotsch.) in a greenhouse

In data combined from three experiments, the degree of control provided by T382 did not differ significantly (P = 0.05) from that provided by weekly topical sprays with chlorothalonil. In addition, T382 significantly (P = 0.05) increased shoot dry weight and salability of flowering plants. Incorporation of composted cow manure (5%, vol/vol) into the light pea

Restrictions on the endothall aquatic herbicide label include the use of endothall treated water for irrigating plants from 7 to 25 days after application.

The affects of endothall on begonias (Begonia semperflorens `Vodka Cocktail'), pansies (Viola × wittrockiana `Atlas Purple'), petunias (Petunia hybrida), and impatiens (Impatiens wallerana `Lipstick') were determined by comparing aboveground dry weight to control p

Abstract:

Micropropagation is an efficient means of producing pathogen-free Elatior begonias. However, the growth of the micropropagated plants can be too luxuriant, flowering is often delayed and the root collars remain thin, all unwanted growth habits in commercial production. To study the effect of growth retardants, an experiment was arranged in spring 1987, in which chlormequat and ancymidol were used on the micropropagated Elatior begonia ’Afrodite Limelight’. Both growth retardants were sprayed at three concentrations: 500, 1000 or 1500 ppm of chlormequat and 37.5, 50.0 or 62.5 ppm of ancymidol.
