Seedling emergence and subsequent survival and growth are vital for natural forest restoration or plantation establishment by means of seeds. Such information is lacking for the African bamboo species. Two experiments were carried out in a greenhouse to evaluate the influence of seed orientation and sowing depth of the lowland bamboo Oxytenanthera abyssinica on seedling emergence, survival and ...
Antagonistic fungi Trichoderma harzianum (T1, from bean fields in Ahwaz, T2, from rice fields in Rasht), T. viride (T3 from bean fields in Shahriar, T4 from the collection in Plant Pest and Disease Institute, Tehran), Gliocladium virens (from bean fields in Kamal Abad, Karaj) and some fungicides (Benomyl, Carbendazim, Carboxin-Thiram, edifenphos and Zineb) were used to control sheath blight of ...
Seedling morphology of 210 species (173 trees and 37 lianas) was studied from a community perspective to identify major patterns of seedling functional types in a Mexican rain forest. Five types of seedlings were distinguished: cryptocotylar with reserve storage or absorption cotyledons (epigeal [CER] and hypogeal [CHR]), phanerocotylar epigeal, either with photosynthetic cotyledons (PEF) or wi...
Seedling vigor is an important agricultural trait as direct-seeded rice technology becomes widely applied. In order to investigate the genetic mechanisms underlying seedling vigor in rice, seeds of 132 recombinant inbred lines (RILs) derived from 93-11 and PA64s, harvested from Lingshui and Hangzhou were cultivated in the nutrient solution, and four indices for seedling vigor were measured incl...
an investigation was initiated to examine the effects of nanoscale titanium dioxide particles on plant growth and development. in view of the widespread cultivation of canola in iran and in other parts of the globe and in view of the potential influence of titanium on its growth, this plant was chosen as the model system. canola seeds were separately treated with different concentrations of nan...
INTRODUCTION In the southern United States, chemicals are an integral part of the management of bare-root nurseries. The rationale for using chemicals is based on economics as they can reduce hand labor, improve the use of valuable seed, and increase seedling performance. The cost of all chemicals associated with loblolly pine seedling production averages less than 0.2 cent per seedling. The co...
