  celastrus
The nonnative woody species Ailanthusaltissima, Morus alba, and Celastrus orbiculatus were absentfrom the aboveground vegetation of some forest plots yet werepresent at low densities in the seed bank.
      
The presence of several key plant species, particularly Celastrus scandens (climbing bittersweet), exhibited a strong control on the spatial variability of LAI and potentially the aboveground net primary production.
      
Multiple shoot buds could be induced directly from internode explants of Celastrus paniculatus inoculated on Murashige and Skoog's (MS) medium containing different growth regulators.

According to laboratory bioassay,the root-bark powder and its et- hanol extracts of Celastrus angulota was proved to have:strong antifeeding action to the adults and nymphs of Locusta migratoria manilensis Mever and the larvae of Athalia rosae japanensis(Rhower);narcotic action to the larvae of Mythimna separata Walker,Pieris rapae L.,Parnara guttata Br. and Anomis flava Fabr.,and also effects of inhibiting reproduction to Sitophilus zeamais Mostchulsky. The results of preliminary plot experiments indicated that the cabba- geworm larvae damaging to cabbage can be controlled by dusting the root-bark powder.It was observed that the larvae of cabbageworm were narcotized for hours after ingesting a little root-bark powder.Then,the narcotized larvae got recovery,fed and became narcotized again.As a result,the larvae gradually starved and died slowly.Owing to narcosis, the survived larvae,particularly 4th-or 5th-instar larvae missed an opportunity to feed again.

用苦树根皮粉对8种农业害虫进行的室内试验结果表明,苦树对不同的昆虫具有不同的效应:对蝗虫(成虫和若虫)、芜菁叶蜂(幼虫)具有强烈的拒食作用,对菜青虫和粘虫、稻苞虫、棉小造桥虫幼虫具有可逆的麻醉作用,但在试验中未观察到对小地老虎幼虫有麻醉作用;苦树对玉米象则表现抑制繁殖的作用。在夏甘蓝和冬甘蓝上进行的防治试验说明,适时施苦树根皮粉一次即可有效地控制菜青虫危害。其原因一方面是因麻醉作用,导致菜青虫饥饿死亡,减少了菜青虫数量,尤其是4~5龄幼虫数量,另一方面则因菜青虫未死前常处于麻醉状态而失去了取食为害的机会.

This paper deals with the morphogenesis of adventitious buds in the stem segments of Celastrus orbiculatus in vitro. The results showed that: The MS basic medium supplemented with NAA 0.01mg/L. plus BA 2mg/L. greatly stimulated the formation of adventitious buds. The medium supplemented with BA(2mg/L.) alone promoted the formation of the adventitious buds. However, when BA was used in combination with NAA in a relatively low concentration, the rate of bud formation was higher. Usually, the tumor-like callus...

This paper deals with the morphogenesis of adventitious buds in the stem segments of Celastrus orbiculatus in vitro. The results showed that: The MS basic medium supplemented with NAA 0.01mg/L. plus BA 2mg/L. greatly stimulated the formation of adventitious buds. The medium supplemented with BA(2mg/L.) alone promoted the formation of the adventitious buds. However, when BA was used in combination with NAA in a relatively low concentration, the rate of bud formation was higher. Usually, the tumor-like callus could be observed on the surface of stem segments, originating in the epidermis or the hypodermis distal to the cut surface of the stem segments. The adventitious buds originated frequently exogenously or endogenously from the meristematic cell masses. The formation of bud primordia was probably relative to the vascular nodules. The adventitious bud primordia could originate from both the epidermis and the hyp(?)dermis, but the bud induced from hypodermis grew more rapidly.

本文报道对南蛇藤离体茎段培养中不定芽的形态发生所进行的研究。以MS基本培养基附加萘乙酸(NAA)0.01毫克/升和6-苄基嘌呤(6BA)2毫克/升进行培养,结果大量地促进了芽的发生。单独加入细胞分裂素6BA2毫克/升,也能促进芽的分化,如果同时加入低浓度生长素NAA,更有利于芽的形成。由茎段表面得到的肿胀状愈伤组织,较专一地起源于远离茎段切口的表皮或下皮层细胞。不定芽一般来自于愈伤组织表层的分生细胞团,有时芽原基的诱导还与维管组织结节有联系。芽原基可以起源于表皮细胞或下皮细胞,然从下皮细胞诱导来的芽,其芽的生长更为迅速。

In laboratory conditions the seed oil of angled bittersweet (Celastrus angulatus Maxim.), termed CA oil, possesses obvious antifeedant effect on Pieris rapae, Aulacophora femoralis, Henosepilachna vigintioctopunctata, Locastra muscosalis, Colaphellus bowringi and Calospilos suspecta.In the field experiments the efficiency of controlling Pieris rapae has been shown as follows: 86.5%, 91.16% and 85.37% obtained respectively by using 2%, 0.66% and 0.5% CA oil; 89.6% by using 10% Cypermethrin diluted 5000...

In laboratory conditions the seed oil of angled bittersweet (Celastrus angulatus Maxim.), termed CA oil, possesses obvious antifeedant effect on Pieris rapae, Aulacophora femoralis, Henosepilachna vigintioctopunctata, Locastra muscosalis, Colaphellus bowringi and Calospilos suspecta.In the field experiments the efficiency of controlling Pieris rapae has been shown as follows: 86.5%, 91.16% and 85.37% obtained respectively by using 2%, 0.66% and 0.5% CA oil; 89.6% by using 10% Cypermethrin diluted 5000 times; and 79.81% by using the root-bark powder of angled bittersweet, which indicates that the controlling effect of CA oil is approximate to that of Cypermethrin and better than that of the root-bark powder.The field experiments have also proved that the CA oil exceeds DDVpboth in controlling effect and in yield increase when used against Aulacophora femoralis.Since the angled bittersweet has not only reliable pest-controlling substance in its seed oil, but also many other advantages, such a bundant resources, wide distribution, strong adaptability and high survival rate, it can be expeeted to be an important source of pest-controlling material and the CA oil to be a very promising natural plant insecticide or antifeedant agent.

室内测定表明:苦皮藤种油对菜青虫、黄守瓜、猿叶虫、28星瓢虫,丝绵木金星■蠖、缀叶丛螟等六种害虫有明显的拒食作用;田间试验效果:防治菜青虫,用2%、0.66%、0.5%的苦皮藤种油防效分别为86.5%、91.16%、85.37%,10%氯氰菊酯5000倍液为89.6%,苦皮藤根皮粉为79.81%,所以,苦皮藤种油与氯氰菊酯的效果相近,但优于苦皮藤根皮粉;防治黄守瓜,其防效与增产均优于DDVp。苦皮藤资源丰富,其种油将有可能成为一种很有发展前途的植物性天然产物杀虫剂或拒食剂。
