摘要:
<正>对来自国内外不同地区不同寄主的24个松树枯梢病菌菌株的培养性状、离体生长速率、产孢特性、分生孢子表面纹饰及致病性等方面的变异进行了比较研究。结果表明:菌株间的培养性状存在显著变异,国内17个菌株可分为两类,第l类菌丝平铺,第2类茵丝为绒絮状气生。国外7个菌株除上述两类,尚存在其他类型。光照和营养是影响产孢的两大重要因素,各菌株在全黑暗的PDA培养基上培养50d以后均产生厚垣孢子。各菌株在灭菌湿地松松针上的产孢量有明显差异。分生孢子表面纹饰与菌株类型无关。各菌株对供试3种松苗的致病性存在明显差异,大多数菌株能无伤直接侵入一至多个松种。大多数菌株在培养性状、离体生长速率、产孢量、分生孢子表面纹饰与致病性等性状之间无明显相关性。
Abstract:
Lycoris radiata is an important ornamental plant in autumn and winter, but its natural propagation coefficient is low. In order to study the effects of the ways of the artificial propagation, the plant growth regulators and the consistence of the plant growth regulators on the quantity and the quality of bulb scales of L. radiata, an experiment of the artificial propagation, was arranged, based on randomized blocks design. The results were as follows=(1)Compared with natural propagation coefficient of L. radiata scale bulblet, the artificial propagation coefficient was much higher. By fractional scale-stem cutting, more but the smallest scale bulblets could be obtained from one bulb. By notching,the least but biggest bulblets could be got. By scoring and boring,more and bigger scale bulblets could be attained. (2)ASL and IBAq-NAA had the best effect on increasing the quantity of bulblets;GAa and 2,4-D in hibited the quantity of bulblets. (3)The effect of consistence of ASL+IBA+NAA on the quantity of bulblets showed that high consistence could inhibit the quantity of bulblets and low consistence could increase the quantity of bulblets.
