Progo River is one of the rivers on the Java Island, which empties into the Indian Ocean, are became the entrance of the glass eels from the ocean. Glass eels were entering the river consists of several species. The aim of this research was to study of the species composition of glass eels that migrated into the estuary of the Progo River. Glass eels collected in the estuary in the year 2007–2009 at the lunar date 28 on at 20:00 until 04:00. In the period of 3 years, was successfully collected as many as 1.110 glass eels, which consisted of 3 species of Anguilla marmorata (31.17%), Anguilla bicolor bicolor (64,32%), and Anguilla nebulosa nebulosa (4.50%). Glass eels migrated into the estuary of Progo River during September to June. Glass eel of A. marmorata migrated to the estuary during September to June, A. bicolor bicolor migrated during October to June, and A. nebulosa nebulosa migrated to the estuary only during February to June.

This research was purposed decide the difference of the vitamin c level of Sidat Fish (Anguilla marmorata (Q.) Gaimard), Glass eel fase, Yellow eel and Silver eel from poso lake and estuary of Palu River.  Materials and Methods: The testing of vitamin c using substance the meet of Sidat Fish (Anguilla marmorata (Q.) Gaimard) Glass eel fase, Yellow eel and Silver eel, vitamin C, metaphospat acid and aquadest with the HPLC method (High Perfomance Liquid Chromatography) with Purposive Sampling technique seen based on the size, place, and fish fase as the requirement for the sample taking. Results: The result showed that Sidat Fish (Angilla marmorata (Q.) Gaimard) with Glass eel fase, Yellow eel and Silver eel from Poso lake and estuary of Palu river was not detected there was the content of vitamin C. Conclusion: Sidat fish (Anguilla marmorata (Q.) Gaimard) does not contain vitamin C.

Over the last several years, there has been increasing interest in amending the soil using cover crops, especially in desert agriculture. One cover crop of interest in the desert Coachella Valley of California is cowpea [Vigna unguiculata (L.) Walp.]. Cowpea is particularly useful in that as an excellent cover crop, fixing abundant amounts of nitrogen which can reduce fertilizer costs. However, soil salinity problems are of increasing concern in the Coachella Valley of California where the Colorado River water is a major source of irrigation water. Unfortunately, little information is available on the response of cowpea growth to salt stress. Thus, we investigated the growth response of 12 major cowpea cultivars (`CB5', `CB27', `CB46', `IT89KD-288', `IT93K-503-1', `Iron Clay', `Speckled Purple Hall', `UCR 134', `UCR 671', `UCR 730', `8517', and `7964') to increasing salinity levels. The experiment was set up as a standard Split Plot design. Seven salinity levels ranging from 2.6 to 20.1 dS·m–1 were constructed, based on Colorado River water salt composition, to have NaCl, CaCl2 and MgSO4 as the salinization salts. The osmotic potential ranged from –0.075 to –0.82 MPa. Salt stress began 7 days after planting by adding the salts into irrigating nutrient solution and ended after 5 consecutive days. The plants were harvested during flowering period for biomass measurement (53 days after planting). Data analysis using SAS analysis of variance indicated that the salinity in the range between 2.6 and 20.1 dS·m–1 significantly reduced leaf area, leaf dry weight, stem dry weight and root dry weight (P ≤ 0.05). We applied the data to a salt-tolerance model, log(Y) = a1 + a2X + a3X2, where Y represents biomass, a1, a2 and a3 are empirical constants, and X represents salinity, and found that the model accounted for 99%, 97%, 96%, 99%, and 96% of salt effect for cowpea shoot, leaf area, leaf dry weight, stem dry weight and root dry weight, respectively. We also found significant differences (P ≤ 0.05) of each biomass parameter among the 12 cultivars and obtained different sets of the empirical constants to quantitatively describe the response of each biomass parameter to salinity for individual cowpea cultivars. Since a significant salt × cultivar interaction effect (P ≤ 0.05) was found on leaf area and leaf dry weight, we concluded that salt tolerance differences exist among the tested cultivars.

Insight Into

Growth response of 22 accessions of Glycine javanica. was studied to detect any significant features that would provide an insight into the mechanisms of salt tolerance. Four levels of salinity, 0.5, 35, 70, and 140 m-equiv. NaCl/l, were imposed in culture solutions for 13 days starting when the plant had three trifoliate leaves. The highest level of salinity had a relatively greater impact on growth than the others. Differences in the dry weight of the glycines at all salinity levels were of similar proportions to those at the control level. This also applied to the laminae, stem f petiole, and roots. The data for plant nitrogen also showed these differences in growth potential at different levels of salinity. The normal capacity for growth of a cultivar seemed to be an important feature in resisting salinity.
