“…The findings also support the hypothesis that higher rate of water uptake is required for elongation growth and higher levels of water content supports higher rate of dry matter accumulation (Rabadia et al 1999). …”

Fibers of three cotton cultivars (Gossypium hirsutum L.) H-4, H-8 and (G. arboreum) G. Cot-15, which shows variation in staple length were analyzed for growth in terms of fiber length and fresh and dry mass. From the growth analysis cotton fiber development is divided in tour distinct phases i.e. (i) initiation (ii) elongation (iii) secondary thickening and (iv) maturation. Rate of fiber elongation and rate of water content shows close parallelism. Highly esterified and less esterified pectic fraction along with high and low molecular weight xyloglucan fractions were estimated from fiber walls of all the three cotton genotypes. Xyloglucans were fractioned in to high and low molecular weight by alkali treatment, 1 M and 4 M KOH respectively. Xyloglucan content shows inverse correlation with fiber elongation. Role of water content and wall components in determination of staple length in cotton genotypes is discussed.

During the entire period of internode growth of Merremia emarginata contents of gibberellic acid (GA 3 ), phenyl-acetic acid (PAA), indole-3-acetic acid (IAA, free and conjugated) and abscisic acid (ABA, free and conjugated) were estimated by ELISA using polyclonal antibodies raised against each hormones. At the time of internode elongation free auxin content was low and increased with the decrease in the rate of elongation. In contrast, conjugated IAA showed declining trend where free IAA content was remarkably high, suggesting thereby that conjugated IAA might have mobilized during the later phase of internode development. The endogenous GA 3 contents were high as compared to other hormones; however, no significant role of GA 3 was discernible in elongation growth. Conjugated ABA contents remained very low during the elongation growth and increased thereafter.

“…Since the fresh weight and dry weights showed close correlation, the water content also showed significant relationship (P< 0.01). A number of the studies have shown that water content plays an important role in increase in the size of cotton fiber (Gokani and Thaker, 2001), cotton seed (Rabadia et al, 1999) and internodes development (Patel and Thaker, 2007). Leaf area in the first stage 20 mm 2 and then gradually increased with different leaf up to 3000 mm 2 .…”

Abstract:Terminalia arjuna is one of the many such plant that used in indigenous system of medicine for curing different diseases. For effective formulation of herbal drug selection of proper age of the plant is imperative. In the present study, the T. arjuna plant (leaves) was collected from the Botanical garden of Saurashtra University. The leaves were grouped in to various size and growth analysis was performed. Each extract homogenized in methanol and was used for chlorophyll estimation and antioxidant activities. Radical scavenging activity of the methanol extract of different stages leaves were determined using a stable free radical 2, 2-diphenyl-1-picryl hydrazyl (DPPH), using Micro plate assay. Further the phenolic compounds were separated by Reverse phase high pressure liquid chromatography analysis (RP-HPLC). At the leaf stage when maximum antioxidant activity was observed, phenol like Gallic acid showed distinct peak. The role of phenolic compounds in antioxidant activities is discussed.
