The present study evaluates the impact of different stimulation frequencies of Ethephon in downward tapping on the production potential of trees in upward tapping of the clone PB 260 of Hevea brasiliensis. Six parameters are measured: production per tree, tapping panel dryness percentage and four latex biochemical parameters which were dry rubber content, inorganic phosphorus, sugar and thiols. The results show that in downward tapping, generally, the biochemical parameters level is inversely proportional to the stimulation frequency during years 9 and 10. Regarding the production, beyond four stimulations per year, it is inversely proportional to the stimulation frequency.

When the trees are tapped upward with a four stimulation uniform per year, the production continues to be low according to the preceding frequency stimulation in downward tapping beyond four stimulations per year. However, the factors which caused this decrease don’t seem to be the same in the first and the second years of upward tapping. In the first year of upward tapping, according to the evolution of the biochemical parameters, the decrease in production is linked to physiological tiredness due to the stimulation in downward tapping. On the other hand, in the second year, it is a phenomenon of familiarization to Ethephon which could explain the decrease in production on treatments which received more than four stimulations per year in downward tapping. In second year of upward tapping, the trees need more than four times per year Ethephon stimulations to reach their production potential. Get the full articles at: Int. J. Agr. Agri.

Abstract

Shepherd's purse (Capsella bursa-pastoris (L.) Medik.) is an annual weed species with a wide distribution in cereals of East Azarbaijan, Iran. Tow experiments were carried out based on randomised complete block design with four replications in Tabriz, Iran in 2014 to evaluate the effects of salinity and drought stress on shepherd's purse germination and early seedling growth. The salinity levels were included 0, 4, 8, 12, 16 and 20 dS m-1 (deci Siemens per meter) sodium chloride (NaCl). The drought stress levels were included 0,-0.4,-0.8,-1.2,-1.6 and-2.0 MPa osmotic potentials were obtained by polyethylene glycol 8000 as osmotica.

Results indicated that the effect of salinity was significant on seedgermination percentage and rate, seedling root and shoot length and seedling dry weight. The all traits reduced significantly by increasing the salinity level. In salinity of 20 dS m-1 the germination% of shepherd's purse was < 35 and the seedling dry weight reduced 65% in comparison with control (0 dS m-1). Also the effect of drought stress was significant on seed germination, seedling length and seedling dry weight and all the traits decreased by increasing the osmotic potential. The germination% of shepherd's purse seeds in osmotic potential of-2.0 MPa was < 32 and the reduction in seedling dry matter was > 60%. Generally, it could be concluded that drought stress such as limited irrigation and salinity would be effective strategy for reduction in germination and early seedling growth of this annual weed species.

Indonesia has at least 47 types of ecosystems, one of ecosystems that have a lot of potential in Indonesia is a mangrove forest. Mangrove forests in Indonesia have a high diversity of flora and fauna. Development and utilization of coastal areas around the mangrove forest, usually not done wisely that is likely to endanger the stability of the mangrove ecosystem in the long term.

One alternative utilization of mangrove forests that could be developed without damaging the environment is the development of ecotourism. Mangrove forest in Pancer Cengkrong Karanggandu is one of the mangrove forest areas with the potential to be developed into a tourist area of mangrove.

The purpose of this research is to study the potential and preferences of flora and fauna (birds) in the Cengkrong Mangrove Forest as a tourist attraction in the development ecotourism programs with community participation. Stakeholders involved in the study consisted of mangrove forest communities, students of nature lovers and a science teacher with a total of 135 people. Data analysis was performed with the help of Microsoft Excel and analyzed descriptively further showed form of graphs.

Result showed that Cengkrong mangrove forests has the potential to be used as ecotourism. Diversity of flora found in the mangrove forest is composed of 22 species with the highest RFC index is Brugueira gymnoriza. While the diversity of bird species found to consist of 21 species with the highest RFC index is Laptoptilus javanicus.
