Morphology and germination

Research on the morphological characteristics, agronomics, pre-harvest germination resistance, and genetic diversity of some popular rice varieties grown in Binh Dinh province is essential in assessing material resources for selecting and developing new rice varieties that can adapt to climate change. The results show that there is one extra short-day variety, five short-day varieties, and three medium-day varieties.

Najas indica (Willd.) Cham. is a freshwater submerged aquatic vegetation. N. indica is an annual plant. Therefore, seeds in the sediment and the survival and growth of seedlings play an important role in reestablishing new populations of the species. The purpose of this study was to determine the seed density in the sediment, examine the effect of salinity on seedling germination from seeds, and assess the impact of the salinity on the growth of early seedlings of N. indica under the experimental condition.

Thirty one mungbean (Vigna radiata L. Wilczek) genotypes were screened for drought tolerance under laboratory conditions in CRD using PEG 6000 at different concentrations of -0.3 MPa, -0.6MPa and -0.9MPa. The genotypes showed reduction in germination percentage and shoot length and increase in root length under water stress condition. Screening of genotypes based on single morphological parameter appears to be limiting due to inconsistency in growth responses of different seedling parts.

More than sixty million Indians reside in endemic areas of fluorosis and are at risk of developing fluorosis in 200 districts from 20 states of India. Keeping in mind the severity of fluoride (F) problems, this study is an effort to investigate the effect of F contaminated soils on germination, plant growth and physiology of important pulse, mung bean (Vigna radiata) and green leafy vegetable spinach (Spinacia oleracea). This study was carried out with completely randomized block design under controlled environmental conditions in green house.

Thirty interspecific crosses (including reciprocals) involving three genotypes/varieties of greengram (Vigna radiate (L) Wilczek) cv. HUM 1 HUM 2 & HUM 8 and five genotypes/varieties of blackgram (Vigna mungo (L.) Hepper) cv. T 9, Pant U 19, PDU 1, BHUU 1 & BHUU 91-346-1 were attempted. Nine out of 30 crosses were successful only when greengram was used as seed parents. The crossability ranged from 0.0 to 61.0 per cent. Germination, survival and pod bearing habit of the F1s hybrids were much better in Kharif season as compared to spring/summer season.

Comparison between aquaponics, hydroponics and traditional method for cultivation of spinach was carried out. In this study, spinach was grown in the soilless media like perlite and sphagnum moss. Medias were used to support plant growth. From these Media the perlite media was used in aquaponics and sphagnum moss was used in hydroponics. This study was carried out to examine different morphological characters like height, germination period, surface area, yield of spinach, and biochemical analysis like protein, carbohydrate, chlorophyll content.

Ninety-three early generation sugarcane clones were evaluated for different morphological and juice quality characters among early generation sugarcane clones. Highest genotypic coefficient of variance (GCV) and phenotypic coefficient of variance (PCV) were recorded for Number of millable cane (NMC) and single cane weight respectively. High heritability coupled with high genetic advance as percent of means was observed for germination percent, NMC/hectare, cane height and inter node length. It indicated that direct selection of those traits would be effective.

This study was performed by exposing the seeds of groundnut (Arachis hypogaea L.) to ethyl methane sulphonate [EMS] sodium azide [SA] to study their effects on various morphological traits when compared with control. The seeds of groundnut were pre-soaked in distilled water for 6 hours for ems and 24 hrs for SA. The SA, EMS solution was prepared in distilled water. Each concentration of SA, EMS was prepared in 100ml of distilled water for 300 groundnut seeds. These soaked seeds treated with different concentration of SA, EMS such as 0.2%, 0.4%, 0.6%, 0.8, 0.10% and 0.12 %.

The experiment was deigned to find out the best alternative way to grow healthy tomato seedling under water stress condition. Three different protected and unprotected conditions (Polyhouse, Low tunnel and open field condition) were selected for sowing of seedling. Open field condition was taken up as a control. Production of healthy and vigorous tomato seedling is most important factor in successful commercial production and yield of quality tomato fruits.

Adiantum caudatum Linn. is an important medicinal fern belonging to the family Adiantaceace, coming under Pteridophytes. It is used traditionally in folklore as ethno medicine to treat various diseases like cough, cold, throat infection, skin disease and diabetes. The in vitro life cycle of A.caudatum L. starting from spore germination, gametophyte formation, followed by micro morphological study and reproductionwas thoroughly studied in knop’s (Kn) and Knudson’s medium (Kc).

Among four isolates of Moesziomyces penicillariae the incitant of pearl millet smut, cultural, morphological and pathogenic variability was studied. The isolates were collected from four different pearl millet growing regions of India. Among the four isolates no variation was observed in size of spore balls but significant variation was observed in their germination percentage. Out of the six different media used, potato dextrose agar medium enriched with 50 g pearl millet grain and 20 g sucrose supported maximum growth of the fungus and least growth was observed in oat meal agar.

Seed treatment with gamma rays, EMS, NG and their combinations in two mungbean genotypes, BKG-1 and OUM 11-5, significantly reduced germination, seedling growth including fresh weight and dry weight, pollen fertility, seed fertility and survival at maturity in M1 over the parents. The biological damage in M1 generation showed a dose dependent linear relationship. NG in both single and combination treatments resulted in more pronounced biological damage than other treatments.
