“…The length and basal area of stem cuttings impound the growth and development of roots in Jatropha plants. Short cuttings favor early sprouting, but long and thick cuttings promote more shoot and root growth (Severino et al 2011). Plant establishment ranged from 25% to 100% in different accessions.…”

Twenty four accessions of Jatropha curcas L. (JCL) were planted on a degraded sodic land in Lucknow, India, in which growth and yield traits were measured over five years (2006)(2007)(2008)(2009)(2010). There was a large variation in growth and yield among these accessions, and the average seed yield (118 g plant −1 ) and oil content (30%) of JCL on the sodic land were sufficiently low to make it an economically feasible venture for biofuel production. The seed:fruit, kernel:seed ratios and the 100 seed test weight were also measured. In order to make it an economically viable proposition, some preliminary screening were done to assort the superior accessions (CSMCRI-C1, NBPGR-Urlikanchan, NBPGR-Chhatrapati, and NBPGR-Hansraj), on the basis of growth and yield traits, that have attained an average height of 264.6-344.6 cm, with an 8.5-to 10-cm collar diameter, 41-57 branches per plant, a 209-to 290-cm canopy spread, a 178-246 g plant −1 seed yield, and a 27-38% oil content at five years. Though they do not correlate well between growth/yield and gas exchange parameters (photosynthetic rate, transpiration, stomatal conductance, and water use efficiency), even then these markers are useful to screen out a large number of accessions at an early stage before the yield starts or stabilizes to increase the land use efficiency. The changes in soil properties after five years of the plantations showed reduction in soil pH and electrical conductivity, with a parallel increase in organic carbon, organic nitrogen, microbial biomass, and dehydrogenase activity, indicating that JCL had a modest ability to reclaim the sodic soils.

“…It is suggested that survival rate and root initiation can be increased by applying endogenous rooting hormones and nutrients before plantation (Soundy et al, 2008;Mori et al, 2011;Ahmad et al, 2012). Therefore, different types of synthetic hormones are being used, among them auxins play a vital role in influencing the root formation and survival rate of stem cuttings (Raju and Prasad, 2010;Severino et al, 2011;Zafar-ul-Hye et al, 2014). But in order to avoid hazards of hormones, the inoculated bacteria which produces growth promoting substances like gibberellins, cytokinins and auxins are alternative to synthetic rooting hormones and have positive impact on plant growth and yield.…”

The role of plant growth promoting rhizobacteria for growth and rooting in Rosa damascena Mill. cuttings was evaluated in this study. Fifteen distinctive and fast growing rhizobacterial colonies (strains) were chosen to inoculate the Rosa cuttings by dipping in them. Growth parameters like shoot length, new shoot fresh weight, new shoot dry weight, root length, root fresh weight and root dry weight showed highly significant results while mortality percentage of cutting was non-significant. Results of the pot experiments revealed that most of the isolates showed growth promoting activities in Rosa cuttings except the isolates B5 which was proved to be growth limiting strain as it gave 20-40% less result for all parameters. The most prominent results were produced by isolated strains F6 (Pseudomonas fluorescens), LSI19 (Rhizobium leguminosarum) and LC4 (Vibrios vulnificus). Isolate LSI19 showed maximum shoot length, new shoot fresh and dry weights with an increase (over un-inoculated control) of 51.6%, 55.2% and 48.0%, respectively. Root growth was positively influenced by isolate F6 with maximum root length and root fresh and dry weights (173.0%, 68.7% and 124.7%, respectively). All the other strains enhanced cutting growth characters up to 30-60% compared to control. Strains LSI19, F6 and LC4 were proved to be superior strains in all growth attributes. Results on the bases of total score obtained by each strain in all growth parameters showed that strains LSI19, F6 and LC4 got first three positions. Therefore, these three strains (LSI19, F6 and LC4) were selected for further studies.
