        Danaus chrysippus L. (Lep.: Nymphalidae) is the most important pest on Calotropis procera Ait. in Bushehr, Iran. The larvae feed on the leaves and make some damages and losses on host. This study was carried out on D. chrysippus life cycle in Bushehr from 2006 to 2007. More
        Danaus chrysippus L. (Lep.: Nymphalidae) is the most important pest on Calotropis procera Ait. in Bushehr, Iran. The larvae feed on the leaves and make some damages and losses on host. This study was carried out on D. chrysippus life cycle in Bushehr from 2006 to 2007. The sampling was carried out weekly by two stage cluster sampling method in nature. For the life cycle studies, the eggs were collected from the nature and were developed in petri dishes and 10×12 plastic dishes from egg to adult under laboratory conditions (25±2ºC and 22±2ºC, %60±10 RH and 16/8 L:D). The results showed that the first adults emerged gradually in February 2006. During the summer and the winter in 2007, any forms of this butterfly have not been observed in Abpakhsh. Incubation period of eggs were 3.4 and 4.5 days; Developmental period of larvae were 12.5 and 19.1 and for pupae 9.8 and 14.6 days under temperatures of 25 and 22˚C at the laboratory conditions respectively. The total period from egg to adult was 26.07±0.8 and 37.08±0.5 days in 25 and 22ºC respectively at laboratory conditions. This butterfly had 5 overlaped generations in a year. Manuscript profile

        Stabragh belongs to the Asclepiadaceae family and is resistant to high levels of drought and salinity. Its organs have been used for the treatment of various diseases. In order to study the adaptation and stability of this plant under drought and saline conditions in Golestan province, Gorgan University of Agricultural Sciences and Natural Resources, plant seeds were cultivated in Gorgan, Gonbad, and Aghghala under different degrees of salinity and drought in February, March and April during 2014 and 2015. Plant height, leaf number and area, leaf dry weight, and proline and chlorophyll contents were measured were significant on all traits. Important traits such as proline, chlorophyll, fresh weight, dry weight, and plant height were introduced as the most important traits during the growth season. Data analysis was done through combined analysis of randomized complete block design. Results showed that the effect of regions on plant height, leaf area and dry weight, and also proline content were significant. Also, the effect of year was significant only for height and number of leaves. Effects of planting date and sampling in the adaptation of stabragh to saline and drought environments. Gorgan was the most suitable area for cultivation. Variations in the cultivation dates led to changes in the plants’ level of adaptation and stability.  The best planting date was April. The findings suggest that the plant can tolerate dry and saline conditions of the region and we can consider it as an alternative plant in arid and saline areas of the province. Manuscript profile

        4 - The survey of synorganization of floral parts and pollinium and pollen germination and tube growth in Calotropis procera (Asclepiadoideae)

        Calotropis procera (subfamily Asclepiadoideae) is one of important medicinal plants in desert and natural resources that has wide distribution in dry and hot areas of southern of Kerman province, Iran. Synorganization of flower is extreme in Asclepiadoideae among angiosperms. Synorganization of flower parts and pollen germination and tube growth were studied. The species contains pentamerous, actinomorphic and bisexual flowers with thick, hairy and white-pink calyx. Corolla is saucer shaped and white-violet that are fused in floral bud and its top part reopened at anthesis. Stamens are attached together through stamen tube and pollinia. Anthers are attached to the stigma to form gynostegium and filaments form a tube around the gynoecium. Stamen tube contains guide rail and corona for pollinator attraction and movement. Each anther contains two thecae, each one has one pollinium (pollen sac) in which pollen grains are united as compact in collective envelope. Two pollinia, one each from two neighboring anthers are connected together by a translator (consists of a clip and two arms.) and form pollinarium apparatus. Thus, pollen grains are not dispersed singly; pollinia are always transported together. The translator does not consist of cellular structure. The postgenital fusion occurs between the anthers and pentagonal stigma and in the upper zone between the two carpels. Synorganisation of flower parts is mostly postgenital. In vitro pollen germination and tube growth was high on basal medium at 300C. One or both pollinia from pollinarium apparatus record pollen germination and tube growth. Pollinia growth showed the unilateral organization. Manuscript profile
