Bio-active essential oil components in small cardamom as influenced by weather elements
The present investigation was performed to evaluate the variability in the yield and bio-active components of Indian cardamom seed extract from two different ecological zones of the Western Ghats (Pampadumpara and Madikeri regions), India. Results showed significant differences in the yield and bio-active components in two varieties viz. Appangala-1 and PV-2. The variety PV-2 (639 g/plant) recorded significantly higher yield in Pampadumpara than Madikeri (399 g/plant). Significant variability was observed in the bio-active components of the essential oil. The intrinsic quality of cardamom is mainly attributed to two important components α-terpinyl acetate and 1,8- cineole. The highest range of α-terpinyl acetate in both the varieties (41.1-42.4%) under Madikeri region was recorded followed by Pampadumpara region (35.01-40.2%), while the 1,8-cineole content showed highest in Pampadumpara (25.68-37.57%) followed by Madikeri (23.06-32.66%) region. The highest content of linalool, α-terpineol, linalyl acetate and cis-geraniol was recorded in PV-2. The highest content of β-neralidol was recorded in Appangala-1. The variation among the region was significant for terpinen-4-ol, β-myrcene and β-neralidol. Pampadumpara region received 47% and 18% more rainfall during North east monsoon (October to November) and summer shower (December to May), respectively though received less rainfall during South west monsoon (71%) and also showed 10% more rainfall distribution compared to Madikeri region. The annual mean maximum temperature (Tmax) was 18% more in Madikeri compared to Pampadumpara region. With all the environment factors taken into account, Pampadumpara region is relatively better in terms of cardamom capsule yield and Madikeri region for bio active components which attributes intrinsic quality of capsules.
STUDIES ON THE ECONOMIC TRAITS OF ERI SILKWORM REARED ON PRIMARY HOST PLANT IN RELATION TO SEASONAL VARIATIONS UNDER ODISHA CONDITION
India is the only country that produces all five commonly traded varieties of natural silk: Mulberry, Eri, Muga, Temperate tasar, and Tropical tasar. Eri silk is the type of silk produced by Samia ricini. Eri silk is often referred to as Non-Violence silk or Peace silk. It is also known as "Poor Man’s silk." We studied how several seasons impact the rearing performance of Eri silkworms by analyzing multiple larval parameters (larval duration, pupal duration, fecundity, hatching, ERR%, emergence rate and survival rate) and cocoon parameters (cocoon weight, shell weight, and shell %). The current research has been conducted using the tray rearing method, which involves placing castor leaves over the worms on wooden trays. This study examines the economic significance of cocoon and post-cocoon characteristics of eri silkworms raised in various seasons. The research showed that economic traits of eri silkworm were most pronounced in autumn and spring season under Odisha climatic conditions.
Quality analysis of Assam Lemon (Citrus limon L.) through HPLC after application of plant growth regulators
Assam Lemon (Citrus limon L.) is considered as one of the most important citrus fruits grown in the north-eastern part of India. In spite of its heavy market demand, recent reports indicated an increasing trend of consumer dissatisfaction associated with inconsistent fruit quality. The present work aimed to improve the fruit quality of Assam Lemon by hormonal regulation. Different concentrations of GA3 (20, 40 and 60ppm) and NAA (10, 20 and 30ppm) were applied at three different growth stages of the plant. Various quality attributes of harvested fruits were analyzed. Chromatographic (HPLC) technique was employed for separation and quantification of oxalic, citric, tartaric, D-malic and ascorbic acids. Fruit juice content and TSS-Acidity ratio were positively influenced by GA3 60ppm. Organic acid content of fruit juice was found to be altered by GA3 and NAA. However, significant differential quality attributes were recorded between GA3 and NAA treated fruits. It can be inferred that the fruit quality of Assam Lemon can be appreciably improved by foliar application of GA3 and NAA.
GC-MS analysis of essential oil from Salvia officinalis cultivated in Mascara region (North West of Algeria)
Salvia species is among the most important plants of the Lamiaceae family; it is an aromatic plant rich in essential oils used in food, cosmetics, perfumes and pharmaceuticals. This work aims to examine the sage essential oil from Mascara region (North West of Algeria). The essential oil was isolated from aerial part of Salvia officinalis by hydrodistillation and volatile compound were analyzed using gas chromatography coupled with the GCMS spectrometry. The results showed that sage provides a higher yield of essential oil. The chemical composition of Salvia officinalis essential oils varies widely, and three major chemotypes have been identified α- Thujone (15,49%), Camphor (15,21%) and Eucalyptol (11,26%). Other important compound were Viridiflorol (4,55%), β-Thujone (3,56%), 1-Naphthalenepropanol, .alpha.-ethenyldecahy (3%), Camphene (2,76%), β- Pinene (2,21%), Borneol (1,72%) followed by α- Pinene (1,29%) and α- Terpinolene (1,18%).
Optimizing seed germination testing protocol for Hedge Lucerne [Desmanthus virgatus (L) Wild]
Hedge Lucerne [Desmanthus virgatus (L) Wild] is a highly variable perennial legume fodder crop critical for forage needs. However, it encounters challenges due to insufficient availability of quality seeds, attributed to poor seed production potential and limited knowledge in seed production technology. To address this issue and ensure seed quality, research aimed to develop seed testing procedures for Hedge lucerne. The study evaluated the effect of media, temperature and counting time on Hedge lucerne seed germination. Tests incorporated three different media types – top of paper, between paper and sand combined with constant temperatures of 20° C, 25 ° C and 30° C, as well as an alternate temperature of 20/30° C. Results revealed that the between paper method and the alternate temperature of 20/30° C exhibited the most favourable outcomes for seed germination. This combination recorded the highest germination per cent (84 %), root length (11.3 cm), shoot length (5.4 cm), seedling dry weight (23.75 mg/ 10 seedling) and vigour index – I (1994). Moreover, the study identified specific timelines for various germination stages: days required for initiation of germination (2.3days), germination of 50 per cent of seeds first count day (3.5days), onset of seedlings withering (11.7days) and the start of seedling mortality (12.2days). Consequently, it is recommended to take first count on the 4th day and the final count on the 12th day, as seedling withering become noticeable beyond this period in Hedge lucerne.
