Neocucumis kilburni sp. nov. (Echinodermata : Holothuroidea : Cucumariidae) from the east coast of South Africa,with a key to the genus Neocucumis     

Vish Rajpal  Ahmed S. Thandar 《African Zoology》2013,48(4):195-199

A new dendrochirotid holothuroid, Neocucumis kilbumi, is described from waters 50 meters deep, off the southern coast of KwaZulu-Natal, South Africa. It appears quite close to N. watasei (Ohshima) and N. sordidatus (Sluiter), both from the West Pacific and to N. atlanticus (Ludwig & Heding) from the Atlantic Ocean and the Mediterranean Sea. It differs from the former in the nature of the calcareous ring and the disc and the spire of the body wall tables, from N. sordidatus in the completeness of its deposits and the number of polian vesicles and from N. atlanticus in the presence of handles to the quadrilocular table discs. The new species increases to ten the number of species now classified in the genus Neocucumis. A key to all the species is included.  相似文献   

Bacterial top rot: a new disease of the potato     

G. S. Shekhawat  B. B. Nagaich Rajpal  V. Kishore 《Potato Research》1976,19(3):241-247

Summary ‘Top rot’, a new bacterial disease of potato was found to occur in India. Water-soaked lesions developed on succulent stems, petioles and leaves. On stems and petioles the lesions enlarged into stripes turning black, which ultimately enveloped the affected portion and caused a soft rot, resulting in toppling of the stem/leaf. The affected tissues were covered with whitish bacterial exudates under high humidity but became dried and shrivelled under dry conditions. Leaflet infection occurred through infected petioles, via mid-rib and veins, or through the margins, resulting in rotting and blighting. The bacterium also caused soft rot of tubers. The disease was favoured by high humidity and a temperature range of 25–30°C. The causal bacterium was identified asErwinia carotovora var.carotovora.  相似文献
