“…In case of seed priming more grains spike -1 (40.18) were produced by water soaked seeds and less number of grains spike -1 (39.33) were produced by dry sown seed. Our results are in line with the findings of [16,27] who reported that in mung bean grains pod -1 enhanced by treated seeds. who stated that seed priming increased grains weight and biomass.…”

A field trial was carried out to investigate the effect of seed priming on the productivity of late sown wheat during fall-2016. The experiment was laid out in randomized complete block design (RCBD) with split-plot arrangement having three replications. Two factors (sowing dates and priming) were tested in the experiment. Sowing dates (29 th Oct, 10 th Nov, 24 th Nov, 10 th Dec, 26 th Dec and 10 th Jan) were assigned to main plots, while priming (non-primed and primed) was allotted to sub-plots. Wheat variety "SIRAN-2010" was sown in a plot size of 1.8m x 5m. Results showed that wheat crop sown on 29 th Oct resulted in early emergence (6 days), increased emergence m-2 (139) plant height (101.61cm), spikes m-2 (280), grains spike-1 (46.63), thousand grain weight (44g), biological yield (9770 kg ha-1) and grain yield (4038 kg ha-1). Late sown wheat in (10 th Jan) took lesser days (136) to maturity. In case of seed priming early emergence (11 days), more emergence m-2 (102), taller plants (85.19cm), more spikes m-2 (216), higher grains spike-1 (40.18), maximum 1000-grains weight (37g), maximum grain yield (3116 kg ha-1) and maximum biological yield (7630 kg ha-1) was recorded in plots sown with hydro-primed seed. However, dry sown seed took more days (163) to emergence. Hence it is concluded that sowing from 29 th Oct to 10 th Nov significantly increased yield and yield related components of wheat. Similarly seed priming is necessary for higher yield of late sown wheat.

A literature survey of the interactive effects of CO2 enrichment and temperature on plant development and growth, indicated that the responses cannot be interpreted within a simple framework. For example, although plant development is generally accelerated by increased temperature, CO2enrichment can accelerate it even further in some instances, or CO2 enrichment may have neutral or even retarding effects in other cases. Where the temperature and CO2 effects are additive, it is argued that CO2 is operating in the same way as radiation to reduce a carbon limitation. If this were true, CO2 enrichment would be most likely to accelerate development in tropical regions during the low-radiation monsoon season. Similarly, while it would be expected that CO2-enrichment would have increasingly enhancing effects with increasing temperature on phytomass growth, this is not invariably the case. In extreme examples which followed the expected trend, plants grown in twice-normal CO2-enriched atmospheres performed progressively better than those grown at current levels of CO2 by 8.7% for every 1°C rise in temperature. However, the difference between the two CO2 treatments more commonly increased by only around 2% for every °C rise in temperature. Of examples examined, both sunflower and nodulated cowpea showed the reverse response to temperature, while non-nodulated cowpea, supplied with luxuriant levels of nutrition, showed no interaction with temperature but a strong interaction between CO2 and radiation. Other aspects of the environment such as nutrition and radiation strongly modify the responses to temperature. It is also clear that plant factors such as stage of development can alter the response to CO2. Long-term studies with several species are required which will take into account many environmental variables within a realistic envelope. One methodology for doing this is presented. There was no evidence among species that responses to CO2 arise through any consistent change in morphology such as via increased branching or increased leaf number. Plant plasticity is such that responses can be expressed in a variety of ways determined by other environmental variables.
