A field experiment was undertaken from September to March for two consecutive years (2020 and 2021) to find out the best time for shoot bending in Hybrid Tea rose. Growth and development of rose cultivar Minu Pearle, was significantly influenced by shoot bending at different time (4th week of September to 4th week of December). Among the treatments tallest plants & maximum leaf area was produced in plants bended on T5 whereas, the plant canopy was registered to be maximum in 2nd week of December. The highest rate of shoot elongation at 15 & 30 days after shoot bending was noted in second week of November and October respectively. Application of shoot bending on 2nd week of October recorded early blooming and slowest flower bud emergence was registered in T5whereas, delayed sepal reflex and maximum days taken to attain cup shape was observed in T6. In terms of flower quality parameters like length and diameter of flower bud and pedicel and weight of individual flower, T5 proved to be superior. Shoot bending applied on 2nd week of November (T4) produced long and thick stalks. Among the treatments maximum number of flowers, longest self and vase life, highest dry matter production from leaves and stem, greater chlorophyll and anthocyanin content was observed in T5.

An experiment was conducted from September 2019 to March 2020 to examine the effect of different combination of foliar applicable fertilizers on Hybrid tea rose cultivar Mohana. The study was performed with 9 treatments (T1-RDF, T2- KNO3 2.5g/l, T3- KNO3 5.0g/l, T4- Soluble fertilizer (Sujala) 1g/l, T5- Soluble fertilizer (Sujala) 2 g/l, T6- KNO3 1g/L+ Soluble fertilizer (Sujala) 1g/l, T7- KNO3 1 g/l + Soluble fertilizer (Sujala) 1.5g/l, T8- KNO3 1g/L + Soluble fertilizer (Sujala) 2g/l, T9- KNO3 1g/l+ Soluble fertilizer (Sujala) 2.5g/l) and 3 replications. From this study T8 (KNO3 1g/L + Soluble fertilizer (Sujala) 2g/l) gave best in case of vegetative and flower quality parameters and minimum days from FBE to cup shape and flower. While in case of cup shape to full bloom minimum days was taken in T1(RDF).

Abiotic stresses are major concerns in agriculture sector affecting large parts of India. It is caused by Drought, salinity and temperature (high/low) representing a major constraint over crop growth rate and productivity. In ornamental crops meagre efforts have been done towards this way. Now a day’s ornamental crops are the prospective way to earn higher income as compared to the other crops and have a significant role in national GDP. How can we grow Ornamental crops in stressed condition is one of the major challenge. To get tolerance power against abiotic stress various ways have been developed but among all methods very few have been proved worthy in case of ornamental crops. Interspecific and intergeneric hybridization is the basic way found hopeful strategy to improve tolerance against drought in some crops through domesticating abiotic stress-tolerant gens from their wild species into cultivated. Combination of both tissue culture and induces mutation approach (In vitro mutagenesis) is the one more important way for bringing stress tolerance and improvement in yield and quality of Ornamental crop plants. Genetic engineering is the modern tool which is used for breeding programme. The introduction of innovative characteristics such as new colours, biotic and abiotic stress tolerance in ornamental crops are usually difficult through predictable breeding, but by the use of genetic transformation we can get is easily.
