The document discusses the relationship between vegetative and reproductive physiology of mango. It summarizes three papers that study the vegetative and reproductive growth patterns of mango cultivars. The key points are: mango exhibits a biennial bearing habit where trees produce maximum vegetative growth in off years and higher flowering and fruit production in on years; maximum vegetative flushes occur from April to August; summer flushes generally result in higher reproductive growth and fruit weights compared to spring and autumn flushes.

Training is an important operation in grapes.
It helps to maintain the stature and spread of the vine and facilitates operations like pruning, intercultivation, spraying and harvesting.
Many training systems are in vogue in India, but the most popular are Bower, Telephone and Kniffin systems.
Wilt is a pernicious disease of guava in India.
In India the disease was first recorded near Allahabad in 1935 . The infection was reported 15 -30 %.
The disease is a serious threat to guava cultivation in U.P. In West Bengal it reduces the yield in affected orchard by 80% .
The disease is also prevalent in Haryana Rajasthan , A.P ,
Punjab and M.P.The exact cause of the disease is still not fully understood but the pathogens viz. Fusarium oxysporum f. sp. psidii (Prasad, Mehta & Lal), Rhizoctonia spp. (Taub.) and various pathogens are reported by different workers may be the incitant of the disease.
Survival and spread:
Through movement of plants containing sick soil in virgin areas.
Short distance spread is by water.
Root injury predisposes wilt disease.
It has forced uprooting of about 150 acre of guava orchard in Panjab and 300 acres in Haryana during 1971-81.

Induced Mutagenesis of Flowering, Phenology and Yield in M1 Generation of Bam...ijtsrd
A highly cherished Bambara groundnut variety, ‘Caro’ was treated with different concentrations of ethyl methane sulphonate EMS for different durations to raise an M1 generation. In the M1 generation, the mutagenic effect of EMS on seed germination, growth and seed yield at different doses 0.01 , 0.1 , 0.25 and 0.5 and for different durations 6 hours, 12 hours and 24 hours were studied. Characters like days to first flowering, days to 50 flowering, number of flowers per plant, number of leaves, number of nodes per plant, number of stems per plant, plant spread, plant height, number of branches per plant, pod length, pod width, number of pods per plant, number of seeds per plant, seed length, seed width and seed yield were measured. Data collected were subjected to analysis of variance ANOVA and means were separated using least significant difference LSD . The result showed that there was significant effect p 0.05 of ethyl methane sulphonate concentrations in all the parameters except on number of days to maturity. The concentration, 0.1 and soaking duration of 6 hours was more promising in creating variability. Apparently, could Ethyl methane sulphonate significantly improved the performance and create genetic variability of Bambara groundnut and therefore can be employed in breeding programme for Bambara groundnut.

The Moss- Physcomitrella patens : A Novel Model System for Plant Development...Senthil Natesan
The moss P.patens has been used as a versatile experimental model organism for the past 80 years and it falls in the division Bryophyta. Being relatively simple in morphology and it generates only few tissues that contain limited number of cell fates (Mark leech et al., 1993), it is extensively being undertaken by plant biologists on both basic and applied strategies covering major areas namely developmental biology, evolution, systems biology, biotechnology ,biodiversity etc., As the organism is predominantly haploid in nature, it is evident that it could allow to develop insights on straight forward investigation/understanding of plant systems and hence, it is amenable for genetic and molecular level studies (Cove., 2009). The availability of complete genome sequence information, genetic and physical map ease the utilization of P.patens in all most all the fields of biology (Yasuko Kamisugi., 2008). It is the only land plant with an efficient system of homologous recombination in its nuclear DNA by which specific gene targeting could be achieved and the strategy of loss of function mutants can be generated by RNAi approach. In this context, the functional genomics of P.patens helps in identifying novel genes which could be employed in metabolic engineering and stress tolerance like drought, salt and osmotic stress thus helps in improving the crop plant performance. Moreover, it serves as a valuable platform for the production of recombinant pharmaceuticals (Anna K. Beike., 2010) Thus, the transfer of novel genes from P.patens has a greater biotechnological impact and may help in better public acceptance. Hence, this presentation aims to confine the advantages of this model plant in plant molecular research by discussing its efficiency in reproduction, range of technologies applied, some interesting characteristic features behind this model and chosen case studies will establish the model behaving as a well-versed medium for wide variety of approaches
