Stimulation Of

Infiltration of pale colored cranberries with gibberellic acid (10−4M, 10−5M), malathion (0.38 × 10−4M), indoleacetic acid (10−6M) and galactose (10−2M) stimulated the development of anthocyanin pigment. Galactose (0.5 × 10−1M, 0.25 × 10−1M) and sucrose (10−1M, 0.5 × 10−1M, 0.25 × 10−1M) inhibited pigment production. The experimental berries all had much lower total pigment contents than well colored, vine-ripened berries. The ratios of the four main pigments were also different. The stimulation of pigment production was not great enough to influence consumer acceptance. However, the results were sufficiently encouraging to suggest that further experiments were justified.

General Acceptability

In order to obtain information on the quality characteristics and acceptability of meat from N’dama (YN) and Muturu (YM)  breds of cattle, the young bull were slaughtered about 11 months of age and their Longissimus dorsiI (LD) and  Psoars major (PM) muscles subjected to chemical evaluation of the raw meat as well as eating quality characteristic of the meat cooked for 10, 15 and 20 min. these were compared to meat from mature Sokoto Gudali (SG). Result showed that meat from NY and YN had similar moisture content but differed significantly (P<0.05) in fat contents. Meat from YM and YN bulls had higher moisture but lower fat content compared to meat from SG bulls. The LD muscles had higher % fat in the three experimental groups than the PM muscles. Total protein and ash contents were similar for all samples but protein solubility was higher (P<0.05) in YN young bulls compared to mature bulls. YN and YM had similar ultimate pH but these young bulls had lower ultimate pH than mature bulls (P<0.05). Total pigment contents varied (P<0.05) between breeds, maturity and muscles types with YM having higher myoglobin than YN, PM higher than LD and mature bulls more that young bulls. Sensory colour and odour of meat varied (P<0.05) between samples with meat from mature SG bulls being rated lower than those from YM and YN bulls after cooking for 10 and 15 minute, all samples were acceptable but their tenderness varied between samples, with the young bulls meat being rated as (P<0.05) more tender than mature nulls but on cooking for 20 min, judges could detect significant differences in juiciness, flavor, tenderness and general acceptability of samples. Generally, meat from young bulls were adjudged more acceptable that meat from mature bulls.

Salt stress elicits various physiological and growth responses of oil palm. A laboratory experiment was conducted to determine the responses of oil palms cultured in vitro under varying salinity levels (0, 85.5, 171.11, 342.21 and 684.43 mM NaCl) to elevated CO2 (1000 μmol CO2/mol) and PPFD (100±5 μmol m-2s-1) in terms of growth characteristics, pigment contents and photosynthetic abilities. After 14 days of culture, net photosynthetic rate (μmol CO2 m-2s-1) of oil palms across varying salinity levels was 5.33 times higher than those cultured under ambient CO, (380±100 Mmol CO2/mol) and PPFD (50±5 μmol m-2s -1). At increased net photosynthetic rate (elevated CO2 and PPFD), despite having no significant difference in pigment contents (chlorophyll a, chlorophyll b, total chlorophyll and carotenoid) between different CO2 and PPFD levels, dry weight and percent dry matter were 0.26 and 0.11 times higher, respectively, as compared to those cultured under ambient CO2 and PPFD. In the same elevated CO2 and PPFD level, across all salinity levels, stomatal conductance was 0.30 times lower than those cultured under ambient CO2 and PPFD. At reduced stomatal conductance (elevated CO2 and PPFD), transpiration rate was also reduced by 0.30 times. Thus with increased net photosynthetic rate and reduced transpiration rate, water use efficiency was increased by 7.22 times, across all salinity levels, than those cultured at ambient CO2 and PPFD. These were considered essential for NaCl produces iso-osmotic stress.

Uav Images

Remote sensing is one of the modern methods that have significantly developed over the last two decades and nowadays provides a new means for forest monitoring. High spatial and temporal resolutions are demanded for accurate and timely monitoring of forests. In this study multi-spectral Unmanned Aerial Vehicle (UAV) images were used to estimate canopy parameters (definition of crown extent, top and height as well as photosynthetic pigment contents). The UAV images in Green, Red, Red-Edge and NIR bands were acquired by Parrot Sequoia camera over selected sites in two small catchments (Czech Republic) covered dominantly by Norway spruce monocultures. Individual tree extents, together with tree tops and heights, were derived from the Canopy Height Model (CHM). In addition, the following were tested i) to what extent can the linear relationship be established between selected vegetation indexes (NDVI and NDVIred edge) derived for individual trees and the corresponding ground truth (e.g., biochemically assessed needle photosynthetic pigment contents), and ii) whether needle age selection as a ground truth and crown light conditions affect the validity of linear models. The results of the conducted statistical analysis show that the two vegetation indexes (NDVI and NDVIred edge) tested here have a potential to assess photosynthetic pigments in Norway spruce forests at a semi-quantitative level, however the needle-age selection as a ground truth was revealed to be a very important factor. The only usable results were obtained for linear models when using the 2nd year needle pigment contents as a ground truth. On the other hand, the illumination conditions of the crown proved to have very little effect on the model&rsquo;s validity. No study was found to directly compare these results conducted on coniferous forest stands. This shows that there is a further need for studies dealing with a quantitative estimation of the biochemical variables of nature coniferous forests when employing spectral data acquired by the UAV platform at a very high spatial resolution.
