This machine generates vibration to shake fruit trees withprovision to hold the tree trunk up to 2438 mm high. Besides, a collecting basket made of green net with fully opened diameter of 6706 mm has also been developed. Performance assessment of the machine was carried out on Aonla and Jamun fruit trees at two different stroke rates and compared with the traditional method of fruit harvesting. The best results were obtained at stroke rates 1480 ± 8 and 1600 ± 12 rpm for Aonla and Jamun trees, respectively. The average harvest per tree at these stroke rates was 52.99 kg and 12.53 kg for Aonla and Jamun trees, respectively. Mature, immature, and damaged harvested fruits were 78.59%, 5.59% and 15.81%, respectively, for Aonla. In Jamun, the mature, immature, and damaged harvests were 82.34%, 7.10%, and 10.56%, respectively. The overall fuel consumption for harvesting Aonla and Jamun fruits was 5.6 and 6.06 l/h, respectively. For Aonla, the cost of harvesting with the machine was Rs. 5.03/kg, whereas it was Rs. 20.94/kg for jamun. In contrast, the cost of harvesting in the traditional method was Rs. 4.20/kg for Aonla and Rs. 15/kg for Jamun. The cost of operation was higher due to the harvesting of untrained, non-pruned treesand the machine being a functional prototype. The overall saving in labour was 74-80% in Aonla and 75-80% in Jamun fruit harvesting compared to the manual method","PeriodicalId":13449,"journal":{"name":"Indian Journal of Horticulture","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135865169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of culture media and supplements on the proliferation of cultures during the micro-propagation of two peach rootstocks ‘Sharbati’ and ‘Flordaguard’ was studied. In both Prunus genotypes, the proliferated cultures decreased from 77.3% and 67.0 % after the first sub-culture to 35.3 % and 27.3 % after the third sub-culture in ‘Sharbati’ and ‘Flordaguard’, respectively.

The highest proliferated cultures (79.0% and 70.7%) and shoot number per culture (4.2 and 3.7) were recorded after the third subculture, in ‘Sharbati’ and ‘Flordaguard’, respectively with QL medium. Both the rootstocks varied in their response to iron chelates. The higher proliferation rates were obtained with MS medium by substituting Fe-EDTA (0.1 mM) with Fe-EDDHA (0.1-0.3 mM) in ‘Sharbati’ and with Fe-Na EDTA (0.1 mM) in ‘Flordaguard’.

The long generation time required by papaya plants during the breeding process significantly slows crop improvement, and developing a variety takes 15-16 years (7-8 generations). As a solution in this direction, using plant bioregulators (PGR) to improve seed maturity in conjunction with the embryo culture technique may aid in reducing the time between fruit set and seedling establishment. We investigated the effect of ethrel, abscisic acid (ABA), and methyl jasmonate (MeJa) in different concentrations during early fruit development on hastening embryo maturity followed by embryo culture for shortening the breeding cycle of dioecious papaya var. Pusa Nanha. Fruits after 60 and 75-days old fruit (DOF) were treated with ethrel (100, 120 ppm), abscisic acid (10-6, 10-4 M), and MeJA (10-5, 10-3 M); the effect of treatments was observed after 15 days of PGR application. Among the treatments, ethrel 120 and 100 ppm at 75 DOF were found to be effective fo hastening seed maturity, as measured by seed colour (light brown), embryo formation (85%), and embryo size (2.93 mm), maximum in vitro germination (85%), rapid shoot emergence (5.67 days), earliest radicle emergence(2.67 days), resulting in maximum plantlet regeneration (86.67%). The embryos isolated from the fruits treated with MeJA (10-5 M) showed the maximum number of roots (5.13), with 75.50 % plantlet regeneration. As a result, using the above method, the breeding cycle of papaya could be reduced to as low as 3 months, compared to the standard period of 6-9 months (from pollination to seedling establishment).","PeriodicalId":13449,"journal":{"name":"Indian Journal of Horticulture","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135865317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was undertaken at the research farm of the Division of Floriculture and Landscaping, ICAR-IARI, New Delhi, during the winter season. Ten chrysanthemum varieties were screened to understand their response to salt stress (150 mM NaCl) and tolerance mechanisms. Salt stress significantly affected osmolyte accumulation and physio-biochemical attributes of chrysanthemum varieties against control. Red Gold variety performed well in terms of growth and yield attributes, indicating its ability to tolerate the salt level of 150 mM NaCl. The highest leaf proline content was recorded in var. White Prolific followed by var. Tata Century. NaCl stress caused a 3/2-fold and 1/2-fold increase in the level of Na+ and K+ ions in leaf tissues of most varieties against control Shoot K+/Na+ ratio was recorded highest in variety Tata Century followed by variety Discovery. From the experiment, vars. White Prolific, Red Gold, Tata Century, and Discovery were found to be more tolerant due to better osmotic adjustments through the accumulation of proline, relative performance under salt stress for plant growth, flower yield, photosynthetic pigments and high K+/Na+ concentration to better sustain under saline condition than the susceptible varieties. PCA analysis revealed that the sum of principal components PC1 and PC2 explained 59.0% of the variations among the varieties. Plant height, chlorophyll content, and fresh weight number of branches had the highest positive loading value, i.e., ~0.7, and leaf proline content had the lowest loading value, i.e., ~0.08, indicating the strongest influence on PC1 and PC2.","PeriodicalId":13449,"journal":{"name":"Indian Journal of Horticulture","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88216206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results obtained from the experiment indicated that the fruits packed with an ethylene absorber exhibited an extended shelf life of 72 days when stored at 13.5°C. The fruits remained fresh for 20 days when stored at RT. These ethylene-treated fruits also displayed the highest pulp-to-peel ratio (PPR) of 7.34 when held at 13.5°C, while the highest acid content (0.673%) was registered at RT. On the other hand, the control group fruits stored at RT tended to show the highest TSS content (29oBrix). The fruits stored at RT, irrespective of the treatments exhibited the highest content of TSS (21.11oBrix). The physiological loss in weight increased gradually during storage in both temperatures but was low in fruits packed with moisture absorbers. Though the ethylene evolution rate increased towards extended storage in both temperatures, the concentration was less in fruits packed with ethylene absorber.","PeriodicalId":13449,"journal":{"name":"Indian Journal of Horticulture","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75157456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
