Poplar is economically important and fast growing tree species which is widely adopted by farmers of northwest India. The nursery study was conducted for two years to find out clonal variation for plant height, collar diameter, biomass, wood traits and incidence of leaf spot disease. Results found significant differences among the clones for all growth traits, specific gravity and fiber length. Clones L-290/84, 22-N and L-50/88 were promising for tree height and collar diameter during 1st year study. In 2nd year the tree height was highest in L-7/87 but was at par with L-34/82. L-7/87, L-247/84 and L-48/89 were promising for diameter. Clones L-48/89, L-7/87, 22-N, L-247/84, S7C8, and WSL-22 recorded superiority for both above ground and root biomass. The maximum fiber length was recorded in clone WSL-29 (0.936 mm) which was at par with those of WSL-22, L-17/92 and L-50/88. The wood specific gravity ranged from 0.383 to 0.498. Clone L-290/84 was at top rank but statistically par with 40-N, G-48, L-50/88 and T-90. The relative resistance for leaf spot was the higher in L-290/84, 40-N and WSL-29 in 1st year, and WSL-29, L-17/92, L-290/84, 22-N, 40-N, S7C8, and L-48/89 were found to be resistant during 2nd year. On the basis of all the traits clones L-48/89, 22-N, L-290/84, 40-N, and WSL-22 have shown promise and need to be tested at multiple sites before commercial cultivation.

“…The results of present study are similar with the findings of Kumar et al (2017) and Tomar and Srivastva, (2020), in which they reported the internodal length of poplar ranges from 4.40 to 5.80 cm after one year of planting. Similarly, significant inter-clonal variation in poplar clones was reported globally in literature (Mir et al, 2017;Sidhu and Dhillon, 2007;Singh and Singh, 2013;Stener and Westin, 2017;Ahmed, 2020). --------------------------------------------------------------------------------…”

The study was conducted to explore the growth performance of the 19 promising clones of poplar at 12 and 24 months after planting. Data were statistically analyzed for different growth parameters viz., colour of buds (after one month), total height, collar diameter, inter-nodal length, number of branches, volume index at first and second year. Taxonomic evaluation (colour of buds) revealed that the clonal characters further represent the source of germplasm from poplar of section Aigeirous. Results revealed that clone C-5 showed significantly better performance for total height, collar diameter, inter-nodal length and volume index, Clone C-7 and PL5 had a higher number of branches in comparison to other clones. Clones SOLAN-13, SOLAN-8 FRI-72, FRI-100 and WIMCO-62 were also found to be the promising clones for growth parameters. Clones C-5 showed better performance for all above mentioned growth characters over other clones.

Zanthoxylum planispinum var. dintanensis is an ecological and economic tree species widely planted in the canyon area of the Guizhou Karst Plateau. However, the rapid growth decline of its plantation in large scale has become one of the major environmental problems affecting vegetation restoration and the consolidation of the achievements of rocky desertification control. In this study, we collected soil samples in the full bloom period (March) and the vigorous growth period (June) from the declining and normal-growing Z. planispinum var. dintanensis communities. Through analyzing fertility quality indexes such as water content and nutrient levels, the mechanism of water-fertilizer coupling affecting the growth decline of Z. planispinum var. dintanensis plantation was explored. The results showed that the pH of soil was about 7.0, and there was no significant difference between the two types of communities. The surface soil water content of the declining community was <20%, which was significantly lower than that of the normal-growing Z. planispinum var. dintanensis community. The deficiency of quick-acting nutrients (e.g., available Ca, Mg, and B) and the imbalance of the medium and trace elements could cause the growth decline of Z. planispinum var. dintanensis, indicating that we should pay attention to the addition of quick-acting nutrients and their stoichiometry in the management process of Z. planispinum var. dintanensis. The comprehensive analysis showed that the decrease of soil water content induced the water-fertilizer coupling deficit effect, which might be one of the reasons for the growth decline of the Z. planispinum var. dintanensis community, in view of the fact that there are many factors causing the growth decline of artificial forest and the mechanism is complex. In the future, it is necessary to systematically study the growth decline of Z. planispinum var. dintanensis community from the perspectives of environmental media, root exudates, plant endogenous hormones, soil microorganisms, and water-fertilizer coupling based on the variations in time and space.
