ऊतक  संवर्धन विधि द्वारा अखरोट (जुगलन्स रेजिया) का सूक्ष्म प्रसार Walnut seedling rootstocks have a very long juvenile period, while the seeds produced remain dormant for about 120 days. Although vegetative propagation through cuttings may be an option, this method is less viable, due to low rooting efficiency. जुगलन्स रेजिया, जिसे आमतौर पर फारसी अखरोट के रूप में जाना जाता है, मध्य एशिया का एक महत्वपूर्ण अखरोट फल है। हालांकि इसकी किस्मों की उपज क्षमता अलग-अलग होती है और दुनिया भर में व्यापक रूप से वितरित की जाती है, प्रजनकों और किसानों के सामने आने वाली समस्याएं काफी समान हैं। अखरोट सीडलिंग रूटस्टॉक्स की किशोर अवधि बहुत लंबी होती है, जबकि उत्पादित बीज...

ऊतक संर्वधन के उपयोग द्वारा केले की खेती Banana (Musa spp.) is believed to have originated in South Eastern Asia with India as one of the centres of origin apart from Indonesia, Philippines, and Malaysia. Bananas are believed to have been the world first cultivated fruit. Banana ranks first in production and second in area among the fruits grown in India. Banana is one of the popular fruits in India because of its low cost and free availability. Banana provides a balanced diet than other fruits. Banana is composed of mainly water and carbohydrates which provides energy (104 Cal. Per 100 g.) It is rich in Minerals, Phosphorus and Calcium. The major problem...

सोमाक्लोनल वेरिएशन: फसल सुधार के लिए एक तकनीक Plant tissue culture procedures give a substitute strategy for vegetative propagation of horticultural crops. Clonal propagation through tissue culture (popularly known as micro propagation) can be acknowledged generally quickly inside a little space. The consistency of individual plants inside a clone population is a significant bit of choice of clonal cultivars in business creation. However, genetic variations do happen in undifferentiated cells, detached protoplasts, calli, tissues and morphological qualities of in vitro raised plants. In 1981, Larkin and Scowcroft begat an overall term ''somaclonal variation'' for plant variations got from any type of cell or tissue cultures. Somac1onal variation has been used in an enormous...

बागवानी में जैव प्रौद्योगिकी  की भूमिका  इन विट्रो कल्चर तकनीकों में लगभग 60 साल पहले फल की फसलों के लिए कई अनुप्रयोग हुए हैं। जिनमें गुठलीदार  फलों के लिए भ्रूण बचाव तकनीक शामिल हैं। जो बाद में इस विधि को व्यावसायिक रूप से स्वीकार्य, जल्दी पकने वाले आड़ू की खेती के उत्पादन के लिए सफलतापूर्वक लागू किया गया है। इन विधियों को अन्य फसलों के लिए भी अनुकूलित किया गया है उदाहरण प्रजनन कार्यक्रमों में प्रारंभिक पकने और बीज रहित अंगूर दोनों का उत्पादन करने के लिए। ऐतिहासिक रूप से फलों की फसलों के लिए इन विट्रो विधि के तरीकों का दूसरा अनुप्रयोग स्ट्रॉबेरी से वायरस पैदा करने वाली बीमारी को खत्म...

उत्तक संवर्धित केला - बढ़ाये कृषक की आय Bananas are the fruits which now considered as world's 4th dietary staple after rice, wheat and corn. A number of people consume them in one way or the other. Banana (Musa spp.) comes under Musaceae family which have several species cultivated all round the world ( Musa acuminata, Musa balbisiana and Musa × paradisiaca for the hybrid Musa acuminata × M. balbisiana). It is world's largest herb and it is not a tree. The fruit type of banana is berry. A typical banana plant has 8 to 30 torpedo-shaped leaves that are up to 12 feet long and 2 feet wide. It is loaded with a number of vitamins and minerals viz.,  vitamin A,...

फसल सुधार के लि‍ए फसलों में सूक्ष्मप्रजनन  Various methods of tissue culture and molecular biology have shown tremendous potential for creation, conservation and precise characterization of genetic variability for improvement of fruit, field, forest crops, medicinal and aromatic plants. Micropropagation of crops is now one of the best and most successful examples of the commercial application of tissue culture technology. Propagation of plants from very small plant tissues/ parts under in vitro conditions in the laboratory is called micropropagation. Commercial application of tissue culture started in 1970 in USA with the micropropagation of orchids. Since then it has seen tremendous expansion globally both in terms of number of production units and...
