Nursery Performance of Male Clones of Poplar (Populus deltoides Bartr.) under Temperate Conditions of Kashmir Valley

Abstract

Fifteen (15) male clones of Populus deltoides (Twelve clones procured from WIMCO and three local clones) were evaluated in nursery to study their growth performance. The investigations revealed that significant interclonal variation exists for all the selected growth characters. The plant height varied from 179 to 284 cm, collar diameter 17.13 to 27.51 mm, number of branches 3 to 14 and number of leaves 59 to 272 plant-1. The leaf area plant-1 also varied between a minimum of 50 to a maximum of 118 cm2 and the internodal length between 3.28 to 5.77 cm. Significant interclonal variation also exhibited in fresh and dry total biomass of seedlings. Based on the morphological growth, the ranking index for these clones was developed and the clones viz., L-34 (TC), L-34 and 65/27 performed best in terms of ranking index with values 133, 126 and 123 respectively. These clones can be used for mass multiplication and for gradual replacement of female cultivars in the Kashmir Valley.

Nursery screening of poplar and willow clones for biofuel application in Ukraine

“…To estimate the total potential of clones for application as biofuel, both growth (D, H, NoSP, LI, FW) and fuel (CalV, AC and DMC) characteristics during the two years of nursery evaluation were ranked separately for poplars (ranks 1-19) and willows (ranks 1-9). All the parameters, excluding ash content, were ranked in ascending order based on the values obtained (Mir et al 2017).…”

“…There is a great interest in the study of short-rotation forestry based on fast-growing bioenergy trees -mainly poplars and willows -in many countries (Bonosi et al 2013, Lazdina et al 2014, Sabatti et al 2014, Kutsokon et al 2015, Stochlová et al 2015, Mir et al 2017, Pilipović et al 2019, Stolarski et al 2020. Up to now, implementation of short-rotation forestry was poorly established in Ukraine, despite a large extension of unused, non-agricultural land.…”

Intense selective logging of Populus deltoides Bartr. amid novel Covid-19 and its subsequent edge effects and forest fragmentation: An alarming scenario in the plant ecology of Kashmir Valley

“…Yearly seed production gauge of a solitary open-developed tree has been assessed as high as 48 million seeds. Over 15.22 million trees of poplars under distinctive diameter class with complete assessed volume of 5.29 million cubic meters are planted across Kashmir (Mir et al, 2017) and around 90 percent of the volume acknowledged from poplars is acquired from the domain of Populus deltoides. These clones had been effectively incorporated in lots of land use structures and are currently spread in each corner of the Valley.…”
