Fruit rot or bunch rot of oil palm in Hainan Island causes a considerable loss. Investigations show that this disease occurs almost all the year round. In dry seasons it appears as a dry rot and during rainy seasons it turns into a soft rot. Symptoms of dry rot always appear as a bunch of yellow, sometimes brown, colored fruit which are at first moribund, then rot off during the ensuing rain, while those of soft rot are quite inconspicuous at their early stages of development.

Fruit rot or bunch rot of oil palm in Hainan Island causes a considerable loss. Investigations show that this disease occurs almost all the year round. In dry seasons it appears as a dry rot and during rainy seasons it turns into a soft rot. Symptoms of dry rot always appear as a bunch of yellow, sometimes brown, colored fruit which are at first moribund, then rot off during the ensuing rain, while those of soft rot are quite inconspicuous at their early stages of development. The only way to detect its presence is to hold each fruit between the finger and thumb and shake it gently. Sound fruit always remain rigid on the bunch and diseased ones can be easily taken out of their enfolding brackets. In a more advanced stage, the detached ends turn brown or brownish black, often carrying a light growth of fungus mycelium. In severe cases the brown ends turn into a water soaked appearance, emitting a fouly odor. Rot usually commences at the top fruit of a bunch, extending downward and inward, finally engulfing the whole bunch. During our three years of systematic investigation we have noticed that 1. Plants which were well fertilized and fruit bunches hand pollinated yield only half as much rotted fruit as those of unconcerned ones. 2. Fruit rot on well managed level land is decidedly less than on slopes. 3. Plants growing on soils with a fairly high underground water level (about 1 1/2 to 2 meters from ground level) do not yield as much rotted fruit as those on high land. 4. This disease neither spreads from bunch to bunch nor attacks the trunk or the leaf base of the plant. 5. A green rind variety suffers less fruit rot than the purple rind variety. Isolations from points of detached ends of fruit frequently yield species of Fusarium. Gloeosporium and various kinds of bacteria, and inoculations by various methods to healthy fruit have never induced rot of any kind. During the process of isolation, with the help of free hand sectioning of severed ends under the microscope, we noticed the fact that some detachable fruit during their early stages do not harbour any organisms at all. In order to clarify the case, we carefully removed the fruit with their peduncles attached from bunches showing early signs of shedding. These were cut longitudinally along their medulla into sizes good enough for both paraffin embedding and free hand sectioning. Cut sections reveal the fact that some inmature fruits produce abscission layers much earlier than healthy mature fruit. This would indicate that fruit bunches of oil palms under certain adverse conditions tend to shed their fruit. Since each small fruit is held within three spiny brackets, the upward growing fruit can not easily drop out of the socket; hence, it has to rot in situ. Relating all the observations mentioned above, we believe that this disease is of a physiological nature.

三年来作者对于幼龄結果油棕的果穗和果实腐烂的症状、分布、蔓延为害,其发生条件和栽培管理的关系进行了詳細的調查和观察,并进行了病原分离、培养、田间人工接种和試探性化学保护等試驗。同时对果实离层組織的形成进行了切片检查。 結果指出海南十二个地区的幼龄结实棕园普遍出現的花、果、穗腐与环境条件和栽培管理有密切关系。果腐是果实离体后从蒂部組織开始的。从腐果組織中經常可以分离到細菌、炭疽菌和鐮刀菌。多次田間接种証明这些菌对健康果实和果穗均无致病能力。大田喷药无效。看来,油棕果腐病是由于环境坏、管理差的条件下,未成熟或接近成熟的果实产生离层而与果柄分离,再由外界杂菌腐食脫果而致腐烂。可見,本病是屬于非侵染性的生理病害。

玉米青枯病(茎腐病),其主要致病菌之一——禾谷镰刀菌(Fusariumgraminearum),在PSA人工培养过程中极不易产生孢子。作者采用浅盘培养方法综合产生无性及有性子实体,生产量大,操作简便,效果良好。主要技术要点是:PSA斜面菌种转接在麦粒或高梁粒培养基上,25℃扩繁培养6~7天,至基物长满菌丝,后平铺于白磁盘内(即浅盘培养),给予一定光源的照射处理,并经常喷水,保持一定湿度。经48~72小时即可丰产分生孢子及有性子实体,环境适宜温度18~25℃。

The results of studies Conducted in 1978-1979 showed that ?r-ray ir-radiation couid re'ard the ripening of toma oes and peppers, and inhibit the sprouting and rooting of carrots. On the oher hand, irradiation c-ould induce or worsen the browning of tissues of trea(?)ed products, such as (?)he tomato s(?)alds and other brown spots. russe ting of snap beans, and the eolor change of mechanical injuries of garlic flower head stalks. It has been found that the diseases caused by weak pathogens such as Penicillium, Aiternaria, Fusarium and others worsened greatly after irradi-ation, even under 10 Kroentgen dose treatment. This is due to the wea-kening of resistance of the treated products to diseases through physi-ological injury from radiation. On the other hand, radiation produces a disinfectant effect on bean rust, Uromyces appendiculatus,inhibits the de-velopment of telia of rust fungi in storage. From these facts, there fore,we consider that the disinfectant effect from radiation on vegetables depends not only on the sensitivity of products to radiation but also on the possibilities of reinfection of pathogens to products in storage.

1978~79两年的研究表明,γ-射线辐射能够推延番茄、青椒的后熟过程,抑制胡萝卜发根、发芽。但辐射又会促进产品组织褐变,削弱产品的抗病性,从而明显加重由青霉属、链格孢属、镰刀菌属等病原菌引起的病害。菜豆锈病的反应则不同,辐射可抑制其冬孢子堆在产品贮藏中发育。因此辐射能否在蔬菜贮藏中起防腐效应,既要看产品对射线的敏感性,还要看病原菌在产品贮藏中是否会重复浸染。
