I want to edit following section:
1) I as the first editor want to edit the abstract and make new one which I mentioned here.
National maize productivity is very low in Nepal. Increase of maize yield is only possible through hybrid maize technology. Hybrid maize development and their evaluation are principal steps of development of finished hybrid maize cultivar. So, evaluation of fifteen newly bred single cross hybrids of yellow maize has been performed minutely from the standpoint of chlorophyll (chl), N (nitrogen) concentration (conc) and red light absorbance-transmittance (RAT) on the maize leaves. In addition, we had curiosities to extract some scientific information about different patterns of chl in maize leaves and their effects on grain yield determination. The hybrids were examined conducting an RCBD trial of three replications in open natural field in winter in subtropical region in Nepal. In it, seeds were sown on October 3, 2012 plot in two row plot area of 1.4 x 3.0 m2. Five plants were randomly selected for chl, N conc and RAT observations before tassel emergence. After anthesis, observations of chl and N conc implying RAT SPAD (Soil Plant Analysis and Development) measures were taken from the topmost ear (e0 or E0) and third (e3 or E3) leaf above the e0 leaf in ten days interval during entire grain filling (GF). SPAD measures were transformed to total chl and N conc. E0 leaf has been found more grain yield determining than e3 leaf and terminal GF has been found more determining than early GF from the standpoint of correlation coefficients (r ) of GYs with chl, N conc and SPAD measure. From pooled variance analysis; SPAD and chl conc were not significant different in the two leaves and among the hybrids (Hybrids x Leaves x Ages). But, the SPAD and chl conc were significant different among the two leaves and ages (Leaves x Ages) irrespective of the hybrids. Different to the SPAD and chl conc, N conc was significant different in the leaves among the hybrids with respect to ages of the plants among the fifteen hybrids (Hybrids x Leaves x Ages). Thirteen top high grain yielding hybrids (GYHs) 8, 12, 11, 13, 5, 6, 10, 1, 7, 14, 2, 9 and 15 were non-significant different from the standpoint of GY. The SPAD measures were in the non-significant range of 51-55 in e0 leaf in the duration from 95 to 125 d among the fifteen hybrids (FHs). Among the top four high GYHs 8, 12, 11 and 13; hybrid 11 lost chl and N from e0 leaf significantly on 135th d relative to the most of the hybrids. It means that the hybrid 11 could efficiently degrade N containing soluble protein and chl even on e0 leaf relatively. Top listed five high GYHs 8, 12, 11, 5 and 6 (except 13) constantly maintained chl and N conc implying SPAD on the e0 leaf up to the 135th d. In addition, it implies that these five hybrids sent newly up-taken N to kernels without degradation of the proteins and chl from the e0 leaf till the age of 135 d. High GYH 8 had degraded soluble proteins and enzymes and chl conc on e3 leaf and mobilized the degraded N to the kernels more efficiently from the e3 leaf. It is not necessary that maize hybrids must constantly maintain soluble proteins and chl conc during most of early to mid GF for high GY. Instead, diagnostic decline of the soluble protein and chl conc during early to mid GF also accelerate GF phenomena.
2) At the end of the paper: I want to edit by the following sentences.
It is from the report about percent of the soluble proteins out of total cell N (Evans and Seemann, 1989) and other enzyme complexes (Sugiharto et al., 1990; Sugiyama et al., 1984). All these phenomena might be because of failed genetic system of the low yielding hybrids or poor acclimation. Acclimation phenomena can be extracted from reports of 1 to 2 second adjustment phenomena of Kautsky et al. (1960) and 15 to 20 minutes acclimation phenomena of Johnson et al. (1990) which can also happen in winter chilling in subtropical region or combined phenomena of the genetic system and poor acclimation in the region.
