Assessing Growth Parameters from Culm Cuttings of Bambusa vulgaris at the University of Dschang Botanic Garden, West Region of Cameroon: Implications for the Bamboo Resource Base and Rural Livelihoods

Dwindling supplies of bamboo resources and the increase in the demand for bamboo have led to the need for better propagation techniques. This is the only way to ensure the sustainability of the bamboo resource base and improve livelihoods. Thus, this study was carried out to examine the different growth parameters of culm cuttings of Bambusa vulgaris in propagation beds with a substrate consisting of dark soil, manure (compost) and sand in a ratio of 1:1:1. Data on different growth parameters was collected on a daily basis over a three week period and analyzed using appropriate descriptive and inferential statistics. It was found that the different growth parameters (diameter, height, leaves and sheaths) of culm cuttings of B. vulgaris evolved in like manner in three propagation beds. Descriptive statistics for growth parameters of culm cuttings of B. vulgaris showed little or no differences across three shelter/propagation beds (shelter bed 1, shelter bed 2 and shelter bed 3) with 1.4675 ± 1.6172 cm, 93 ± 112 cm, 22 ± 30 leaves, and 4 ± 6 sheaths being the mean diameter, height, number of leaves and number of sheaths for all three propagation beds, respectively. ANOVA test showed no statistically significant variation (p > 0.05) between growth parameters of culm cuttings of B. vulgaris across the three propagation beds, implying that the different growth parameters were relatively similar. Pearson correlation showed the existence of direct and inverse relationships between the different growth parameters of culm cuttings of bamboo. The existence of these direct and inverse relationships could be attributed to the rapid growth rate of bamboo, the substrate used, and the species of bamboo used (B. vulgaris). The study recommends more large-scale propagation projects of this bamboo species in order to ensure the sustainability of the bamboo resource base and improve livelihoods of bamboo dependent rural communities.

Peking University Campus:From Ruined Garden to Yan Yuan

The current location of Peking University used to be the campus of Yenching University which was called Yan Yuan. It is situated in the northwestern suburb of Beijing, neighboring the well-known Qing-Dynasty imperial resorts "Summer Palace" and "Fragrant Hill" and the celebrated Tsinghua University.With the naturally endowed landscape, the northwest of Beijing became famous as ideal scenic resorts as early as 800 years ago. During the Ming and Qing dynasties, a cluster of imperial and private gardens were built on the site of
