Background: Aonla is considered asone of the important indigenous minor fruit crop. Being rich in nutrients the demand of its planting material is increasing day by day which is not fulfilled due to poor seed germination and seedling growth. Therefore there is a dire necessity to standardize the techniques for improving germination and growth of seedlings. The aim of the current study is to overcome the dormancy and to enhance the germination in aonla seeds. Methods: The present investigation was carried out during 2019-2020 under field conditions with the pre soaking application of the aonla seeds with thiourea, GA3, cow urine, sulphuric acid, water and seed stratification for time interval of 12 and 24 hours. In the laboratory the selected samples were analysed morphologically based on shoot, root and biomass traits.Result: Out of the various treatments the application of GA3@ 500 ppm for 24 h have ensured early germination with an increase in seed germination. This treatment also improved the seedling growth with an increase in root formationand vigour index. This study will be useful in boosting the cultivation of aonla which will be beneficial for the growers on commercial basis.

AbstractThe paper presents the results of a study regarding the influence of treatment with zinc in different concentrations (50 mg∕l, 100 mg∕l, 200 mg ∕l, 300mg/l, 400 mg ∕l, 500 mg/l, 600 mg ∕l) on seed germination and growth in early ontogenetic stages ofCucumis meloL. We analyzed the following indicators: the percentage of germinated seeds; the length of root, the length of the hypocotyl and the length of the seedling; the number of the laterale roots; the tolerance index and the seedling vigor index. The results underline the specific variations of analysed indicators, depending on the concentrations used for the treatments of seeds. The concentrations used for treatment do not influence negatively the seed germination, but affected the seedling growth (especially the root elongation), the formation and growth process of lateral roots and the seedling vigour index. The delay effect of growth process is very pronounced in the case of high concentration.

Germination Behaviour

Soapnut (Sapinduas emarginatus) is one of the most primitive precious useful plants since ancient times. This plant was domesticated due to its multifarious usefulness. The study was conducted in College of Forestry, Sirsi during 2019-20 to know the influence of post scarification storage treatments on seed germination and quality in Sapinduas emarginatus. The seeds were collected from in and around Sirsi area. In soap nut, the basic problem is poor seed germination due to hard seed coat. The seeds were treated with concentrated H2So4 for 12min and stored under laboratory condition for six months. At monthly interval, seed samples were drawn and evaluated for post scarification germination. The germination behaviour remarkably influenced due to scarification and without scarification during experimentation. The untreated seeds recorded the maximum germination (68%) compared to scarified seeds (22.85%).Speed of germination was highest in seed without scarification treatment (2.7) compared to scarified seeds. Mean daily germination was highest in without scarified seeds (1.04) and lowest in the scarified seeds (0.32). Peak value was maximum in without scarified seeds (0.50) compared to scarified seeds (0.22). Seedling vigour index was significantly highest in without scarified seeds (1290) compared to scarified seeds (455). In general, scarified seeds with conc. H2SO4 for 12 min affected seed germination due high conc. H2SO4 because of chemical residues remaining in seed that affects the embryo. As the advancement in storage period the seed coat may lose the integrity so, germination was improved in without scarified seeds.

Background: Sesame is an important oil seed crop affected by toxigenic fungal pathogens viz., Alternaria, Fusarium and Aspergillus. Among these, Alternaria sesami is seed borne and most destructive pathogen causing yield loss to an extent of 28.9 per cent. Hence the effect of artificial infection with A. sesami on seed quality of various samples of sesame was investigated during 2017-2018. Methods: A total of 28 samples were collected from different sesame growing areas of Andhra Pradesh and Telangana and inoculated with A. sesami. The inoculated and uninoculated seeds were tested for germination and seedling growth by rolled paper towel method.Result: Significant differences in seed germination, seedling length and seedling vigour index were observed among the uninoculated as well as inoculated sesame seed samples. The results indicated that Alternaria sesami caused 15.13% to 49.68%, 12.77% to 46.14% and 28.28% to 72.87% reduction in seed germination, seedling length and vigour index, respectively, of inoculated seed over uninoculated seeds. The per cent reduction was highest in the seed samples of YLM-17 collected from farmers’ saved seed samples of Prakasam district.

Blood fruit is a tropical underutilized species, fruits of which have been identified as source of natural colourant. However, forests are the major source of fruits to native people. In order to conserve the natural population of this species and promote cultivation, nursery techniques need to be standardized. In the present investigation, effect of three substrates viz. vermicompost, sand and soil + vermicompost was studied on seed germination characteristics. Results revealed significant differences among the treatments. Use of vermicompost improved seed germination (69%) significantly over the other substrates used. Though most of the studied seedling growth parameters did not differ among the treatments, significantly highest seedling vigour index (5466.9) was recorded when vermicompost was used as substrate. Considering these findings, use of vermicompost is advisable for germination of blood fruit in nursery.

Growth Of Seedlings

The growth of three coconut cultivars of the tall type from germination up to 17 months of age was compared by growth analysis. These cultivars differ considerably in mean nut size. Within each cultivar a comparison was also made between the growth of seedlings from small, medium, and large nuts. There were considerable differences between cultivars in seedling growth up to 2 months but these differences did not persist. Similarly differences due to nut size within cultivars were recorded at early harvests but had disappeared by 6 months. Thus neither genotype nor nut size had any sustained effect on the plant size. Consumption of endosperm depended on seed size: evidently a lower, compensating net assimilation rate occurred in plants with large nuts to give a similar total supply of assimilate. This suggests that the potential supply of assimilate was not limiting the growth rate. Large nuts transfer dry matter from the endosperm more rapidly than do smaller nuts; hence under unfavourable conditions for photosynthesis, larger nuts may produce larger seedlings. It is suggested that any seedling selection should be done in a favourable nursery environment so that emphasis is placed on differences in seedling vigour due to genetic variation.

Allelopathic effects of lantana (Lantana camaraL. ♯3LANCA) residues (root, shoot), foliar leachates, and the soil (where lantana was grown) on milkweedvine (Morrenia odorataLindl. ♯3MONOD) seed germination and growth over a 30-day period were examined. Foliar leachates or the soil collected from the field where lantana had been growing had no effect on the final germination percentage or the seedling growth of milkweedvine. Incorporation of dried lantana shoot or root material into soil had no effect on the final percentage germination but caused significant reductions in milkweedvine growth over a 30-day test period. Roots were more inhibitory than shoots. Fifty percent of milkweedvine seedlings died within 15 days after germination at 1% (w/w) dried lantana root incorporation into the soil, and higher concentrations increased seedling death. Lantana roots incorporated into the soil produced foliar symptoms such as wilting and desiccation, whereas lantana shoots incorporated into the soil produced yellowing of the foliage of milkweedvine. Allelopathic activity of lantana residues was still strong even after decomposition of lantana residues for 4 weeks prior to the planting of milkweedvine seeds.

Experiments were conducted to evaluate the allelopathic influence of Rhynchosia capitata on germination and seedling growth of mungbean (Vigna radiate) along with identification of the phytotoxic substances responsible for this activity. Water extracts of root, shoot, leaf, fruit and whole plant were prepared by soaking them in water in a ratio of 1:20 (w/v) for 24 h. All the extracts affected germination and seedling growth of mungbean, but higher inhibition was seen with R. capitata leaf water extracts. A linear decrease in the germination characteristics of mungbean was observed with the decrease in the concentration of leaf extract from 5% to 1%. The soil-incorporated residues (1-4% w/w) of R. capitata stimulated the growth of root and hypocotyl at low concentrations, while it inhibited their growth at higher concentrations. Rhynchosia capitata soil-incorporated residues (4% w/w) significantly reduced the seedling vigour index of mungbean in addition to their significant effect on total germination. A significant amount of water-soluble phenolic acids were found in R. capitata plant extracts. The content of total phenolic acids was higher in the leaf extract compared to that of the stem, fruit or root extracts. Two phenolic acids including vanillic acid and 4‑(hydroxymethyl) benzoic acid were found in R. capitata leaf extracts.
