This paper deals with the histopathological changes caused by VHA-273, a recently isolated NPV from H. armigera. This virus infects mainly the fat body, hypo-dermis, and tracheal matrix. However, the damages of the midgut epithelium, muscles, Malpighian tubes, etc. are not detectable.In serial sections of the diseased larvae, the first symptom to be observed under the microscope is an enlargement of the nuclei of the susceptible tissues which seemed to be affected simultaneously in the haemocoel. After infe...
Both works of [1] and this paper are preparatory for construction of conditioning point processes of a given point process defined on a separable, locally compact metric space. The so-called "conditioning point process" is a generalizr.ti.on of the known Pahm measure and is better than it because the conditioning point process has not only the properties of a measure but also the properties of a stochastic point process. The aim of this paper is to prove an existing theorem of stochastic point processes, co...
“Guangdong Oil No.551-116”and other nine verieties were usedas tested materials for investigating the characters of the anatomicalmorphology of pod development in peanut plant of the Spanish bunchtype and the alternated flowering type.1.In the pod developing process of Spanish bunch type,the dif-ferentiation and development of embryo in the seed can be divided intoeight stages,namely,(1)proembryo division;(2)primordial tissuedifferentiation;(3)cotyledons differentiation and formation;(4)dif-ferentiation of ...
