The mean size of pollen grains of Morinda tomentosa varied in different media with comparatively larger size in distilled water. The pollen viability varied between 83.47 to 95.53% among the accessions. Fifteen to twenty per cent solo sucrose medium appeared precise for pollen germination. The boric acid addition irrespective of concentration (0.005 and 0.01%) in sucrose medium of different concentrations impacted the pollen germination. The germination was highest (85.26%) when 0.005% boric acid was added to 10% sucrose solution. Further, the lower concentration of boric acid (0.005%) evinced better germination of pollen grains than higher concentration of boric acid. The average pollen tube length was maximum (62.42 µ) in 15% sucrose solution while it was minimum (14.36 µ) in 30% sucrose solution indicating intermediate concentration of sucrose medium as appropriate for growth of pollen tube. The addition of boric acid to sucrose medium evinced clear impact on growth of pollen tube with maximum average pollen tube length of 120.74 µ recorded in 15% sucrose medium fortified with 0.005% boric acid. © 2015, IndianJournals.com.

An experiment was conducted on young of NA-7 aonla trees to evaluate the influence of various levels of organic and inorganic nutrient sources on morphomatrix, productivity and quality attributes and soil quality during 2007 and 2008 under hot semi-arid ecosystem. Significant improvement was recorded in soil quality by application of different combinations of cakes, FYM and CPP. The vegetative growth, yield and quality of aonla were influenced significantly by different sources of nutrients. Vegetative growth was recorded significantly highest in the plants treated with farm yard manure coupled with standard dose of NPK. Various treatment combinations of organic nutrient sources increased the fruit yield and quality. Maximum yield per plant (32.15 kg) was recorded with the plants, which were treated with FYM plus standard does of NPK. Quality parameters like TSS, total sugars, vitamin C and total phenols were influenced considerably by the application different organic sources of nutrients. The soil parameters in terms of pH, EC, bulk density, hydraulic conductivity and organic carbon were also improved significantly by different sources of organic nutrients. Considerable improvements in the soil physical and chemical properties were observed by the use of different sources of organic nutrients. Source

A field study was conducted to differentiate the aonla (Emblica officinalis Gaertn) varieties for their vegetative and fruit characters under rainfed hot semi-arid ecosystem of western India during the years 2012-14. Among the cultivars, growth habit was observed upright spreading, tall upright, tall spreading, tall drooping and tall semi-spreading. The foliage was visualized as dense and sparse among all the cultivars. The leaflet colour (green to pale yellowish green), shape (oblong, oval oblong and elliptical), apex (obtuse and acute) also varied among the cultivars. The size of leaves in terms of length and breadth ranged between 1.25-1.47 cm and 0.23-0.37 cm, respectively. The time of fruit set and time of fruit maturity differed considerably among the varieties. The maximum fruit set (51.95%) and fruit retention (26.40%) were recorded in NA 7, whereas same was recorded minimum (36.21%) in Banarasi and Francis (11.34%).Variations in fruit shape, i.e. triangular, flattened oblong, flattened oval, and flattened round, whereas size of the fruit was observed as small large and medium among observed varieties. The highest fruit weight (33.90 g) and specific gravity (1.43) were found in Banarasi while these traits were recorded the lowest in Kanchan and Francis, respectively. The qualitative physico-chemical characters, viz. fruit juice content, acidity, pulp content, vitamin C content, TSS, TSS/acid ratio and stone weight ranged between 40.00-64.45%, 1.34-2.56%, 23.95- 31.95 g, 334.12- 461.76 mg /100gm , 8.00-11.50% and 3.61- 6.74 g and 1.97-2.08 g, respectively. The stone of the fruit also varied with respect to its shape (triangular and oval round) and size (large, medium and small) under rainfed hot semi-arid environment of western India. Source

The present study was undertaken to evaluate the performance of different varieties of bael (Aegle marmelos Correa.), established through in-situ patch budding during the year 2003, at Experimental Farm of Central Horticultural Experiment Station (CIAH), Vejalpur, Panchmahals (Godhra), Gujarat under rainfed hot semi-Arid ecosystem of western India during the years 2010-12. The results of study revealed that the different varieties of bael exhibited considerable variation for vegetative, floral, yield and physico-chemical attributes of bael fruits. The vegetative growth in terms of plant height, stem girth, plant spread (E-W) and plant spread (N-S) varied between 3.38-5.85m, 28.95-88.39 cm and 3.74-7.68 m and 3.40-7.52 m, respectively, while the terminal leaf length, breadth, lateral leaf length and breadth ranged between 10.72-15.02 cm, 5.85-9.38 cm, 7.45-11.38cm and 4.13-6.57cm, respectively. Different varieties of bael exhibited wide variations with respect to morphometrics of vegetative characters under rainfed conditions of western India. Varieties also showed wide differences for floral traits with regards to bud size, flower size and other floral organs. The morphological features of fruit of different varieties, viz. fruit yield (40.50- 69.29 kg), fruit weight (0.43-4.25 kg), length (10.61-19.59 cm), width (9.40-22.00 cm) and fruit girth (29.10-70.00 cm) also showed variations. Physical composition of bael fruit exhibited wide variation in their shell weight (115.25- 560.05g), shell thickness (0.16-0.31cm), number of seed/fruit (90.34-212.25), total fresh seed weight (17.34-43.41 g), number of seed sacs (10.23-19.17), fibre weight (15.91-106.50g) and pulp weight/fruit (0.27-3.67 kg). The qualitative characters of fruit in terms of TSS mucilage, TSS pulp, total sugar, reducing sugar, non reducing sugar, vitamin C, total phenols, acidity and TSS to acid ratio ranged between 37.00-49.50° brix, 30.57-37.45° brix, 16.15-19.98%, 3.30-4.95%, 12.85-15.13%, 17.13-21.03 mg/100g, 2.34-2.75%, 0.30-0.49% and 68.88-124.83, respectively. All the varieties of bael showed significant diffferences for qualitative and quantitative morphological characters under rainfed hot semi arid environment. Source

The vegetative morphomatrix in terms of plant height, stem girth, plant spread, number of primary branches and number of secondary branches varied between 3.10- 4.70 cm, 19.10-36.08 cm, 2.27-3.87 m, 6.23-13.45 and 12.12-26.00, respectively, whereas leaves morphology, viz. leaf length, breadth, petiole length and vein pairs ranged between 15.00-25.00 cm, 8.00-16.50 cm,1.25-2.29 cm and 7.43-11.33 per leaf, respectively. Yield /plant during 3 rd year varied between 3.50-9.41 kg being highest in CHESN 1 and the lowest in CHESN 21 in all the evaluated genotypes. The quantitative fruit characters in terms of fruit weight, length, breadth, number of pyrines, number of seed/fruit and fresh weight of seed ranged between 19.20-47.10 g, 2.49-4.80 cm, 2.34-3.98 cm, 10.95-23.95, 25.17-50.65 and 0.06-0.11 g, respectively. Variations in values of TSS, pH, vitamin C and acidity, protein, phenols, tannins, Ca, K, Na, and Zn ranged between 6-12 0 brix, 3.50-7.00, 21.15-40.15 mg/ 100g, 1.16-1.51 per cent, 0.09-0.29 g, 11.12-20.05 mg, 0.25-0.46 g, 90.10-102.00 mg, 36.12-49.92 mg, 80.16- 93.90 mg and 0.10-0.29 mg among the genotypes characterized for their biochemical composition. Based on the overall observations, CHESN 1, CHESN 16 and CHESN 31 were found to better with respect to most of the qualitative and quantitative characters than rest of the genotypes evaluated under rainfed conditions of western India.
