Selection of fast-growing and adversity resistance Casuarina clones for coastal areas of Fujian
摘要
Abstract
In order to meet the needs of superior clones for Casuarina shelterbelt and industrial raw materials plantation purposes in coastal areas of Fujian Province, a clonal test and comparative experiment involved with 48 candidate clones were conducted in Chihu Forest Farm, Hui'an County, Fujian. Based on analyses and comparisons of growth, survival rates, pest damage rates and wind-resistance of 3-year-old clones, 10 fast-growing clones were selected, viz. Pu20, Huil2, Hui77, YueAl, Yue-hybrid, YueA8-2, YueAl3, Hui65, Zhanjiang3 and Zhanjiang2. Ten high adaptability (higher survival rates) clones were selected, viz. YueA14, Dongshan2, Hui58, Hui78, Hui98, Yue-hybird, Yue701-2, Hui83, Hui95, Yuenanshan7. Ten pest-resistance clones, namely YueA14, Hui76, YueA8-2, Kngtan2, Yuenanshan8, Kangfeng, Kangl, Kang3, Huil3, Long7-18 were selected. Taking advantage of the attack of typhoon 'MERANTT , 10 wind-resistance clones, viz. Hui58, Hui98, YueA14, Long7-18, Hui13, Hui2, Yuenanshan7, Kang8, YueAl-3, Long4 were selected. In addition, according to correlation analyses of 5 measurement parameters, there was not significant correlation between DBH (diameter at breast height) and wind-resistance in Casuarina clones, and very significant negative correlation and significant positive correlation were found between survival rates and pest damage rates, survival rates and wind-resistant abilities respectively. It implies that pest destruction and wind damage exert key effects on survival rates of Casuarina clones.关键词
