polyembryonic rootstocks seedlings to saline irrigation water. Two rootstocks, Dashehari and Bappakai seedlings were subjected to different NaCl concentration (0, 15.8, 31.6, 37.48 and 74.97 g NaCl/10 kg
pot soil). The result indicated that proline content was increased with enhanced salinity level and
recorded the highest 0.042 and 0.033 µg/mg with 74.9 g NaCl salinity level in monoembryonic and polyembryonic rootstocks respectively, while total chlorophyll and carotenoids were decreased with increasing salinity level. Reducing sugar and total sugar increased from 0.003 to 0.010 percent in monoembryonic and 0.003 to 0.014 percent in polyembryonic with increasing salinity level from 0 to
74.9 g per pots, whereas starch content decreased in both type embryonic rootstocks. The polyembryonic seedlings was found more tolerant to NaCl by responding increased proline and sugar content, with low decline in chlorophyll and carotenoid content. Thus, polyembryonic seedlings proved to be the more adaptable rootstock to saline conditions.Not Availabl
Indigenous bahar management practice for improving quality of pomegranate under hot arid climate of Thar Desert
No full text42-52Pomegranate is an ancient fruit renowned for its exceptional nutritional value and is deeply rooted in traditional health-care systems. In hot arid climate, pomegranates exhibit three distinct flowering seasons, traditionally known as "ambe, mrig and hasta bahar‖. The choice of bahar to be regulated depends on irrigation water availability, market demand and pest/disease incidence. The present investigation was undertaken to optimize bahar management and induce synchronized flowering during optimal climatic conditions to enhance fruit quality while minimizing fruit cracking through indigenous horticultural techniques such as water stress, pruning, de-blossoming and defoliation using ethephon. Data revealed that indigenous horticultural techniques and ethephon had a significant positive impact on fruit quality and marketable yield of pomegranate. Among horticultural techniques (P), the most favorable results were observed with water stress during June with pruning and de-blossoming, which yielded maximum fruit weight of 216.58 g, 64.58 fruits/plant, and marketable yield of 11.59 kg/plant, all while minimizing fruit cracking to 11.51%. The horticultural techniques in combination with ethephon applications (PxC) involving water stress during June, pruning, de-blossoming, and ethephon (2 mL/l) demonstrated remarkable improvements. This treatment resulted in improved fruit weight of 223.58 g, a marketable yield of 13.63 kg/plant, and the lowest incidence of fruit cracking of 9.42%. These findings allowing synchronized flowering, enhanced fruit quality and market value. These insights contribute to the sustainable pomegranate cultivation in rural areas of Thar desert and further support its role in traditional health-care system

Effect of different growing media on the rooting of pomegranate (Punica granatum L.) cv. \u27Phulearakta\u27 cuttings
Full text linkTo identify the most efficient growing medium for root and shoot development in stem cuttings of pomegranate cv. ‘Phulearakta’ under arid conditions, a greenhouse experiment was conducted in randomized complete block design with three replications during 2014-15 at ICAR-CIAH, Bikaner. About 15-20 cm long hard wood cuttings, 0.5-1.0 cm diameter and having three to four buds were separated from the healthy trees and planted in mid-January. Detached cuttings were treated with 2500 ppm of IBA (3- Indole butyric acid) using quick dip technique (for 5 seconds) and planted in five rooting substrates i.e.sand, vermiculite, perlite, cocopeat and garden soil (control) alone and in combination at 1:1 (v/v). The response of perlite + vermiculite medium was best in terms of rooting (82.33 per cent), number of roots (32.67 per cutting), fresh and dry weight of roots (0.61 mg and 2.08 mg), shoots per cutting (80.33) and survival (76.0 per cent) than the other medium used. Vermiculite + Coco peat 1:1 (v/v) combination also resulted in rooting in more than 80 per cent of cuttings whereas cuttings raised in garden soil and sand showed very low rooting. Based on the findings, it appears that Perlite + vermiculite 1:1 (v/v) and vermiculite + cocopeat may be appropriate alternatives to the conventially used substrate, i.e., garden soil for the better rooting and establishment of pomegranate cultivar \u27PhuleArakta\u27 cuttings

No full textNot AvailableA greenhouse experiment was conducted to optimize the concentration of growth regulator IBA and to
evaluate the efficacy of growing medium for root and shoot development in stem cuttings of pomegranate
cv. ‘Phule Arakta’ under arid conditions. About 15-20 cm long cuttings, 0.5-1.0 cm diameter and having
three or four buds obtained from the healthy pomegranate trees planted in mid-January. Before planting,
the cuttings were treated with four levels i.e. 1000, 1500, 2000 and 2500 ppm of IBA using quick dip technique
(for 5 seconds) and planted in five rooting substrates i.e. sand, vermiculite, perlite, cocopeat and garden soil
(control). The maximum rooting and survival percentages were recorded in IBA @ 2500 ppm with vermiculite
substrate. Similarly, the maximum numbers of shoots and roots per cutting as well as fresh and dry weights
of roots were recorded with IBA @ 2500ppm in vermiculite. In contrast, IBA @ 2500ppm in combination
with sand and perlite produced the maximum root length in cuttings. These findings suggested that dipping
cuttings in 2500 ppm IBA and planting in vermiculite was the most effective treatment for enhancing
establishment, survival and growth of pomegranate cv. ‘Phule Arakta’ cuttingsNot Availabl
Underutilized Fruit Crops of Indian Arid and Semi-Arid Regions: Importance, Conservation and Utilization Strategies
No full textNowadays, there is a large demand for nutrient-dense fruits to promote nutritional and metabolic human health. The production of commercial fruit crops is becoming progressively input-dependent to cope with the losses caused by biotic and abiotic stresses. A wide variety of underutilized crops, which are neither commercially cultivated nor traded on a large scale, are mainly grown, commercialized and consumed locally. These underutilized fruits have many advantages in terms of ease to grow, hardiness and resilience to climate changes compared to the major commercially grown crops. In addition, they are exceptionally rich in important phytochemicals and have medicinal value. Hence, their consumption may help to meet the nutritional needs of rural populations, such as those living in fragile arid and semi-arid regions around the world. In addition, local people are well aware of the nutritional and medicinal properties of these crops. Therefore, emphasis must be given to the rigorous study of the conservation and the nutritional characterization of these crops so that the future food basket may be widened for enhancing its functional and nutritional values. In this review, we described the ethnobotany, medicinal and nutritional values, biodiversity conservation and utilization strategies of 19 climate-resilient important, underutilized fruit crops of arid and semi-arid regions (Indian jujube, Indian gooseberry, lasora, bael, kair, karonda, tamarind, wood apple, custard apple, jamun, jharber, mahua, pilu, khejri, mulberry, chironji, manila tamarind, timroo, khirni)
