Disease severity was recorded 2 weeks after planting when seedlings were still at the primary leaf stage. In all of the rows planted with inoculated seeds, some of the plants were symptomless and others had leaf spots and puckering symptoms characteristic of bacterial brown spot. No difference in type or severity of symptoms was noted in any of the treatments. None of the treatments resulted in...

Now that multi-tiered plant factories with artificial lighting (PFALs) have demonstrated sufficient proof of concept for leafy green and microgreen production; the next challenge is to determine optimal environment conditions horticultural management practices required produce nutrient-dense plant-based protein (PBP) crops within these advanced controlled systems (CES). Sole-source PFALs energe...

recently, increase in crop production depends on better seedling establishment, emergence rate and uniformity. thus, an experiment was carried out in a randomized complete block design with 8 fertilizer treatments and 4 replications in 2008 at sari agricultural sciences and natural resources university. the aim of this research was to evaluate effect of vermicompost (vc) on bush bean seedling e...

Reproduct ion of Pratylenchus vulnus Allen and Jensen on rose was repor ted faster at 32.2 C than at 23.9 and 15.6 C (6). Reproduct ion on alfalfa tissue was faster at 25 C than at 20 and 30 C (3), while on 'Lovell ' peach and bush bean, reproduct ion was faster at 28.3 C than at 24.4, 20.6, 16.7, and 12.8 C (1). Populat ions of P. vulnus and other species of root-lesion nematodes are often rai...

High resolution growth recording techniques and reverse isotope dilution analysis were used to study the relationship between indole-3-acetic acid (IAA) concentration and curvature of excised bean (Phaseolus vulgaris L. cv Bush Burpee Stringless) first internode sections unilaterally treated with hormone. The maximum rate of curvature occurred rapidly (within 25 minutes) and was proportional to...

Aqueous solution, 10 mm, of cyclohexanecarboxylic, cyclohexylacetic, cyclohexylpropionic, cyclohexylbutyric acids (all components of naphthenic acid); cis-1,2-, and trans-1, 4-cyclohexyldicarboxylic acids; 3-cyclohexene-1-carboxylic and cyclohexylsulfamic acids; and cyclohexyl mercaptan were applied to 14-day-old bush bean plants, Phaseolus vulgaris L. cv. Top Crop. Only cyclohexanecarboxylic a...
