Reproduction of Pratylenchus penetrans on the potato cultivars Hudson, Katahdin, and Superior was determined in greenhouse and field microplot experiments. Although all three cultivars were good hosts for P. penetrans, differences in reproductive rate were found. In one greenhouse experiment, Katahdin plants inoculated with 1,500 or 15,000 P. penetrans per pot had larger population densities at...

Host suitability of olive cultivars Arbequina and Picual to several plant-parasitic nematodes was studied under controlled conditions. Arbequina and Picual were not suitable hosts for the root-lesion nematodes Pratylenchus fallax, P. thornei, and Zygotylenchus guevarai. However, the ring nematode Mesocriconema xenoplax and the spiral nematodes Helicotylenchus digonicus and H. pseudorobustus rep...

Greenhouse and field microplot studies were conducted to compare soybean shoot and root growth responses to root penetration by Heterodera glycines (Hg) and Meloidogyne incognita (Mi) individually and in combination. Soybean cultivars Centennial (resistant to Hg and Mi), Braxton (resistant to Mi, susceptible to Hg), and Coker 237 (susceptible to Hg and Mi) were selected for study. In the greenh...

Sodium alginate, irradiated by Co-60 gamma rays in solid state, elicits plant growth promoting responses in various plants. Irradiated sodium alginate (ISA) was applied as a foliar spray on mint (Mentha arvensis L.) to investigate its effect on plant growth, physiological attributes and herbage yield as well as on content and yield of essential oil and its components (menthol, L-menthone, isome...

Creating a forcing schedule A forcing schedule can be drawn up by using the previously listed cold periods. For example a forcing operation wants to have marketable pot hyacinths with flower clusters easily visible between the leaves on 7 December. If it takes one week to green up and pre-force the plants in the greenhouse, and if the cold period for that cultivar is 10 weeks, the bulbs will ha...

Faba bean (Vicia faba L.) is a highland legume having potential for soil conservation. Upscaling cultivation requires initial inquiry on its growth and yield. In this research, we have investigated bean’s yield in different location (high tunnel open field) under population density (1, 2, 3 plants per pot). We found that interaction between has significant effect number of leaves, shoot fresh w...

paclobutrazol was utilized to analyze its role in water stress amelioration and post drought recovery of container-grown pear ( pyrus communis cv. biroti ) saplings. following planting, paclobutrazol was applied as soil drench at concentration of 0, 0.15 and 0.3 mg per pot. three months following planting, saplings were subjected to three water stress treatments of: 0, -0.4 and -0.8 mpa. contro...

abstract paclobutrazol is one of the most important triazolic compounds which are used as growth retardants in some crops. in this study, the effect of application methods and concentration of paclobutrazol on plant height of tuberose and possibility of pot production was investigated. in the first experiment, tuberose bulbs were soaked in 0, 25, 50, 75 and 100 mg.l-1 paclobutrazol for 10, 20 a...

Abstract To identify if and how the age of in vitro potato plantlets at planting affects later tuber formation, an extensive pot experiment was performed under controlled conditions. In vitro-derived different ages (14, 28, 42 56 days old planting) cultivars varying maturity type (Gloria, very early; Bintje, mid-early; Elkana, late) were grown after for 10 weeks photo/thermoperiods 16 h (standa...
