Abstract:

‘Amidst the Pines’ by Kabita Singhal is a memoir that describes her childhood days at a boarding school in Darjeeling namely Kurseong. The school was surrounded by tall pine trees and was situated in the middle of a forest. The author illustrates many literal roles that the forest played during the formative years of her life as a human being. This study deals with some such examples, from the book, that even have a lot of metaphorical implications. More specifically, this paper examines the nature-human relationship that has been depicted by the author, in light of ecocritical consciousness d

On poor sandy-loamy soil the crowns of trees grafted on Mahaleb were significantly, more than 40% bigger than those on Mazzard cherry. No significant differences in the yielding and productivity of trees grafted on Mahaleb and Mazzard cherry trees were found on grey

Of these species, grey poplar holds significance in forestry, and its role in afforestation shows a growing tendency. For this reason, improving the growing technology of grey poplar is a timely topic. In this paper we introduce algorithms which help estimate grey popla

Abstract:

Growth of micropropagated Japanese persimmon trees (Diospyros kaki L. cv. Nishimurawase) during the initial 3 years after field establishment was compared with that of grafted trees on seedling stocks. Judging from the mean length of annual shoots per tree and the yearly increases in height, trunk diameter, and top and root dry mass, the grafted trees on seedling stocks grew poorly during the first and second growing seasons, while micropropagated trees, raised in an outdoor nursery, developed poorly only during the first growing season. In contrast, micropropagated trees raised in pots fared

Abstract Application of 50 ppm gibberellin (GA3) at full bloom + 2 weeks in 197981 on ‘Montmorency’ cherry trees planted in 1978 reduced flowering the year after application. Treated trees grew larger, presumably due to reduced early fruiting. Projected cumulative grower return during the period 5 years after planting was increased because of GA3 application the first 3 years.

Abstract:

Data on the influence the grey heron (Ardea cinerea L., 1758) colonies have on the dynamics of tree ring parameters in pine plantations are presented. It is shown that the beginning of the stands colonisation by the grey heron can be quite accurately determined by analysing the dynamics of the annual tree rings parameters, especially the width of their late layer and the optical density of wood (the values of the former are lower in the control stand, and of the latter one are higher there). Grey heron colonies begin to appear in pine forests since as early as 10–12 years old, when the height

Abstract Rooted cuttings of ‘Nemaguard’ peach were grown for 10 months in soil infested with or without Criconemella xenoplax (Raski) Luc and Clitocybe tabescens (Fr.) Bres. Trees were pruned in early December and placed in an unheated greenhouse subject to large temperature fluctuations during the winter. In March, 8 of 9 trees infested with C. xenoplax and all infested with C. xenoplax + C. tabescens showed severe stem cambial browning typical of cold injury and did not leaf out, although the root systems were still viable. All check trees and 7 of 9 trees infested with C. tabescens grew nor

Abstract:

The thinning of flowers and fruit sets did not change the strength of tree growth in a signifi cant way. Szampion cv. trees on rootstock A 2 grew better than on M.7. The trees of Szampion RENO cv. grew significantly worst. The thinning of flowers and fruit sets decreased the yield from a tree and the total yield from 1 ha of the studied biological material. Flower thinning slightly increased the mean commercial yield as compared to the control trees. Thinning of 50% of flowers at the stage of the pink bud and sets after the June fall decreased the number of fruits on the trees of Szampion cv.

A commercially available copper-treated disk was evaluated for its effect on weed suppression for container-grown willow oak (Quercus phellos L.). No weeds grew in containers where disks were used.

Abstract:

Significant differences may exist in establishment rate between trees planted from containers and those from field nursery. Containergrown plants have root balls with deflected roots which could impact establishment. Slicing root balls at planting could improve postplanting performance of container-grown trees. Sixty live oak 170 L containers were planted into landscape field soil. Root balls from 30 of these containers were sliced prior to planting. Thirty field-grown trees of slightly larger size, and 30 smaller trees from 57 L containers, were also planted. During dry periods in the first 4

Trees standing side by side had similar height and diameter increment patterns, i.e., high and low increments in identical years. With increasing distance, this similarity rapidly decreased even on identical forest sites. On different sites, the patterns were different, often opposite.

Abstract:

Three Japanese tree lilac (Syringa reticulata) cultivars, 2 each in 11 communities, were planted for evaluation as street trees. Cooperators in the Municipal Tree Restoration Program using standardized methods measured them annually for 3 years, and periodically afterwards. 'Ivory Silk', 'Regent', and 'Summer Snow' performed well at all locations. All 3 cultivars grew slowly initially, and their foliage tended to turn yellow in late summer. Height growth of 'Summer Snow', reputed to be slower than 'Ivory Silk', was not slower at all locations.

In areas of sympatry with grey squirrels, there are concerns about red squirrels’ dependence on certain coniferous tree species in light of recent tree diseases. Aims This study aimed to investigate tree selection by red squirrels in an area vulnerable to the spread of the grey squirrel, but currently free of this species.

The first use of chemical weapons, along with the problems posed by their disbursement and disposal, also still affect the soil of the Western Front, as well as the trees

Survey respondents were not very concerned about potential problems with trees in cities, and felt that trees should be planted in cities regardless of any annoyance.

Radial growth data were taken from increment cores. Aspen trees on the south and west sides of the lake grew 20–25% faster than aspen in north and east side stands.

We analyzed changes in tree cover using remote sensing data and compared the radial growth of coexisting and defoliated Pinus halepensis trees and non-defoliated P. halepensis and Pinus pinaster trees. We also compared NSC concentrations in leaves and sapwood of defoliated and non-defoliated P. halepensis and Quercus ilex trees. I

Abstract:

Much research in forest ecology has been devoted to examining the effect of gap formation on regeneration dynamics. However, comparatively little research has examined the process of gap closure, in which larger trees bordering the gap grow laterally to exploit available light. Thus, it remains uncertain whether disturbance disrupts or reinforces the competitive hierarchy established among different species and sizes classes. We quantified the lateral growth of three hardwood tree species with differing autecologies both before and after the formation of small gaps created by single-tree selec
