Comparison Results

The present investigation was carried out at Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan during the year 2014 -2015 to study the “Effect of cold plasma treatment and priming on bell pepper (Capsicum annuum L. cultivar California Wonder) for seed germination and seedling vigour. The seeds were ex-posed to various durations of oxygen plasma treatment using glow discharge technique at FCIPT, Institute for Plas-ma Research, Gandhinagar, Gujarat, India. Seeds were pre-treated with power of 100 W for treatment durations of 0, 3, 6, 9, 12, 15 minutes for 0, 4, 8 and 12 month durations. The changes in surface morphology of plasma treated seeds were studied by Scanning Electron Microscopy (SEM) and Contact Angle Goniometer. Along with plasma treatment, seeds were also treated with standard priming method i.e osmoprimng for comparison. Results showed that plasma treatment alone as well as in combination with osmoprimng up to 6 minutes duration had positive effects on seed germination and seedling vigour. Germination and vigour indices significantly increased by 21.75% and 90.71% respectively. Characteristics of germination percentage, speed of germination, seedling vigour index-I & II, significantly increased by 13.92%, 1.39 cm, 0.38 mg, 322.07 respectively, compared with control. And it was found that immediately after plasma exposure the germination (84.41%) and vigour (228.50) was highest and it was reduced to (73.54%) and (174.27) after 12 months of storage. These results indicated that cold plasma treatment might promote the growth and modify the speed of germination i.e. higher speed of germination was observed in seeds exposed to plasma treat-ment for 6 minutes (59.82%), whereas, lowest germination speed (40.76%) was observed in untreated control.

Capsicum Annuum L

Plant growth promoting bacteria are known to directly or indirectly influence the development and yield of plants. Studies that show the biotechnological potential of these bacteria as biofertilizers are thus important. The objective of this study was to evaluate the growth capacities of strains M2-7 and LYA12 and define whether their interactions with Capsicum annuum L. increases production. The hypothesis was that the Bacillus licheniformis strains have capacities to promote growth and yield of Capsicum annuum L. First, these strains were evaluated in vitro in selective culture media to detect those direct or indirect mechanisms for plant growth promotion. Then, the effect of both strains on seed germination and the effect of strain M2-7 were studied on the in vivo development of C. annuum L. The experimental design was completely randomized with 3 treatments and 3 repetitions. Data was analyzed with ANOVA and Tukey test (p≤0.05). Results showed that the bacterial strains were able to fix nitrogen, solubilize tricalcium phosphate Ca3 (PO4)2, produce gibberellins, lytic enzymes (amylases, proteases, lipases and esterases), biosurfactants, volatile compounds; and significantly inhibit growth (p≤0.05) of the phytopathogenic fungus Colletotrichum sp. Likewise, the strains M2-7 and LYA12 increased (p≤0.05) by 89 and 78% the seed germination of C. annuum L. M2-7 enhanced fresh weight (235%), stem diameter (308%), root weight, number and weight of fruits (316%), as compared to treatment 1 (Nitrofoska) and 3 (Control). Therefore, B. licheniformis M2-7 strain is attractive to develop the formulation of biofertilizers; aiming to improve yield of some horticultural crops towards a sustainable and ecological agriculture.

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.

This research aimed to carry out the response of seed germination and seedling growth of Calina papaya to the seed soaked in coconut water. It was conducted from April to June 2017. The study comprised two designs of experiment i.e. the Completely Randomized Design for the seed germination and the Randomized Complete Block Design for the seedling growth of papaya. There were 25 treatment combinations obtained and each treatment was replicated three times. The treatment factors comprised the concentration and the duration of seed soaked in coconut water. The results showed that the seed immersion in the 80% concentration of coconut water for 8 hours had the highest growth rate and vigour index. Meanwhile, the seed immersion in the 60% concentration of coconut water for 8 hours showed the highest percentage of germination. The seed immersion for eight hours resulted in the seedling growth of papaya.

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.
