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.
Effect of Cattle Dung and Gypsum on Growth of Indian Major Carp, Rohu (Labeo rohita) Fry under Sodic Soil Conditions
The present study was conducted to determine the effect of Cattle dung and gypsum on the growth performance of Labeo rohita under sodic soil conditions. In a 90-day study, circular tanks having 500-liter water holding capacity were fertilized with seven different treatments viz. Feed+ Soilbase (control), Feed + Soilbase + Cattle dung(@15t/ha/m), Feed+ Soilbase + Cattle dung(@25t/ha/m), Feed+ Soilbase + Cattle dung(@30t/ha/m), Feed + Soilbase+ Cattle dung(@15t/ha/m+ Gypsum@5t/ha), Feed+ Soilbase + Cattle dung(@25t/ha/m+Gypsum@5t/ha), Feed+ Soilbase + Cattle dung(@30t/ha/m+Gypsum@5t/ha) named control, T1,T2,T3,T4, T5 and T6 respectively. Various parameters of water quality such as pH, ammonia, alkalinity, hardness, total dissolved solids, dissolved oxygen, growth parameters like weight gain percentage, SGR, FCR as well as survivability of Labeo rohita fry were also assessed during the experimental period. The initial and final soil parameters such as pH, EC, Exchangeable Sodium Percentage (ESP), Organic carbon percentage (OC%), nitrogen, phosphorous, potassium, exchangeable potassium, exchangeable calcium, and exchangeable magnesium were also monitored. The growth and water quality parameters were also compared to the control group (where only soil base and feed were given). The objective of this study is to provide general information on sodic soil characteristics and water quality parameters specifically to study the survival and growth of Labeo rohita fry under different treatments of Cattle dung and gypsum which could ultimately enhance the overall soil and water quality. The information can be used to determine appropriate soil management based on soil characteristics so that the unutilized sodic soil can be used for fish production. Exposure of fish at treatment T6 where a higher dose of Cattle dung and gypsum along with soil base and feed was given were found to have significant improvement in fish growth rate, survivability, and water quality. The present result suggested that the application of Cattle dung along with gypsum at (6:1 ratio) improved the survival of Labeo rohita fry and also enhanced its growth.
Uncovering the seed germination and initial vigour potential of quality protein maize inbreds
Quality protein maize assures nutritional security with improved tryptophan and lysine content. Maize inbreds, in general, and QPM inbreds, in specific, suffer from low germination and seed storability. High seed germination and strong vigour of QPM inbreds contribute to the development of QPM hybrids with favourable field establishment and initial vigour. The present study aims to assess the variability in seed germination and vigour of twenty-eight elite QPM inbred lines developed in the QPM breeding programme and to identify the superior ones for further use. The mean germination percentage for all the inbred lines studied was 88.64%, with most inbred lines exceeding the minimum seed standard of 80%. However, a wide variation was observed for two important vigour traits, radicle emergence (RE) and electrical conductivity (EC). The RE varied from 28 to 96%, while the EC ranged from 14.13 to 109.35 µScm-1g-1. Interestingly, the inbreds with high germination showed significant variation in RE and EC. The correlation studies revealed a weak positive correlation between germination and RE while a significant negative correlation between germination and EC. Thus, the inbreds with high germination, good RE (%), and low EC identified from the present study can be used for developing QPM hybrids with good germination and increased initial seed vigour.
