Zinc Uptake in Loblolly Pine Seedlings
… pine (Pinus taeda L.) were measured in 72 seedlings grown in washed sand, fertilized with Zn(N03)2. Zinc treatment periods were early spring, late spring, and summer. Zinc uptake was the greatest in early spring. Zinc nitrate fertilizer and remaining soil zinc at treatments end had no …

Physiological effects of BA and ABA on caixin seedlings
… by Asians, yet potential health benefits of its seedlings are hardly explored. This study aimed to determine physiological effects of BA, ABA, and heat stress on caixin seedlings. BA application maintained juvenility of caixin seedlings, as concentrations of chlorophylls and carotenoids, and …

Effects of Some Events Experienced by Seedlings in Competition
… that randomly occurring factors that affect seedlings can be dominant forces in determining the fitness of individuals, (2)to examine the effects of one such factor, defoliation, on final plant size and (3)to examine the dynamics of the growth response of defoliated and undefoliated plants.

Regulation of desiccation tolerance in Xerophyta seedlings and leaves
… desiccation tolerance in seeds and germinating seedlings in angiosperms, particularly the epigenetically silenced seed maturation genes. Germinating seedlings of X. humilis and the related resurrection plant X. viscosa were found to be VDT from the earliest stages of germination, and exhibited …

Drought-Tolerance Comparison of Aleppo Pine and Brutia Pine Seedlings
<p>Seedlings of Pinus halepensis and P. brutia were grown from seeds in a greenhouse. When 6 months old, randomly sampled seedlings were subjected to water stress by withholding irrigation. During this period, foliage and root characteristics of seedlings not under moisture stress were recorded. …

Lateral development in roots and shoots of Pinus radiata seedlings
Under natural conditions, short-roots of pines usually occur in intimate association with basidiomycetous fungi, forming symbiotic relationships known as ectomycorrthizas. Although mycorrhizas have been most extensively studied in regard to their nutritional contribution to host plants, there is …

Seedborne fusarium and root colonization of container-grown douglas-fir seedlings
… root colonization of container-grown Douglas-fir seedlings was studied in two coastal Douglas-fir seedlots; one contaminated with Fusarium and the other with minimal Fusarium. Seedlots were treated using either a standing water imbibition, or a running water imbibition with a post-stratification …
