Salinity is one of the major and increasing problems in irrigated agriculture in Pakistan. Salinity stress negatively affects the growth and yield of plants guar (Cyanoposisa tetragonoloba). This experiment was conducted to evaluate the effects of ($4dSm^{-1}+13.5(mmol\;L^{-1})^{1/2}$, $5dSm^{-1}+25(mmol \;L^{-1})^{1/2}$, $5dSm^{-1}+30(mmol\;L^{-1})^{1/2}$, $10dSm^{-1}+25(mmol\;L^{-1})^{1/2}$ and $10dSm^{-1}+30(mmol \;L^{-1})^{1/2}$) on biomass yield of guar against salinity tolerance. Maximum biomass yield ($54.50gpot^{-1}$) was produced by $4dSm^{-1}+13.5(mmol\;L^{-1})^{1/2}$ treatment. Biomass produce was reduced with the increase of the salts toxicity. Minimum biomass yield ($30.17gpot^{-1}$) was attained under $10dSm^{-1}+30(mmol \;L^{-1})^{1/2}$. $5dSm^{-1}+25(mmol\;L^{-1})^{1/2}$ treatment exhibited improved outcome i.e. the least diminution % over control (18.66). Salinity cum sodicity showed staid effect on the growth reduction from 18.66% to 44.64%. This reduction fissure was impacted by the toxic effect of salinity and sodicity on Guar growth. Salinity- sodicity behaved toxic impact on the growth reduction from 18.66% to 44.64%. Based on the findings, guar (Cyanoposisa tetragonoloba) grows better at $4dSm^{-1}+13.5(mmol \;L^{-1})^{1/2}$ treatment.

Salinity with sodic condition disturbs germination, retards emergence, and slow down seedling development of Lemon Grass (Cymbopogon citratus).Lemongrass is a perennial grass plant widely distributed worldwide and most especially in tropical and subtropical countries. This research experiment was designed to evaluate the influences of (4 dSm^-1+ 13.5 (mmol L^-1)^-1/2, 5 dSm^-1+ 25 (mmol L^-1)^1/2, 5 dSm^-1+ 30 (mmol L^-1)^1/2, 10 dSm^-1+ 25 (mmol L^-1)^1/2 and 10 dSm^-1+ 30 (mmol L^-1)^1/2) on biomass produce of lemon grass against salt tolerance. The uppermost biomass yield (45.53 gpot^-1) was produced by 4 dSm^-1+ 13.5 (mmol L^-1)^1/2 treatment. The increase in the intensity of salts reduced the growth of lemon grass. Lower biomass yield (79.33 gpot^-1) was gained at 10 dSm^-1+ 30 (mmol L^-1)^1/2. 5 dSm^-1+ 25 (mmol L^-1)^1/2 treatment performed enhanced outcome i.e. the least reduction % over control (5.87). Salinity- sodicity showed serious effect on the growth reduction from 5.87% to33.60%. This reduction gap was affected by the negative effect of salinity and sodicity on Linseed growth. Salinity- sodicity showed severe impact on the growth reduction from 5.87% to33.60%. Based on the findings, lemon Grass (Cymbopogon citratus).was capable to grow up the maximum at 4 dSm^-1+ 13.5 (mmol L^-1)^1/2 treatment.

Cosmetic activities of the leaves of Curcuma longa L. were compared according to different drying methods, to expand the use of the by-products of Curcuma longa L. The highest extraction yield of 29.4% was obtained from vacuum drying process (VD), whose value was very close to 29.2% from freeze drying process (FD). Relatively lower extraction yield were observed as 24.5% and 25.3% from the raw leaf (RL) as control and hot air drying process (HD). The cytotoxicity was observed lower FD and VD than RL and HD. It shows that cytotoxicity was closely related to cosmetic activities such as tyrosinase and melanin inhibition activities by showing much better cosmetic activities of the extracts from both FD and VD than those from the RL and HD. It was interesting that was differences of the cosmetic activities and cytotoxicity between FD and VD, which implies that VD method should be a more efficient process than FD method in terms of drying time and operation costs: 6 hours vs 24 hours and 3-5 times higher extraction costs in drying. It was observed that VD is more excellent dry method than others. This result could be utilized to effectively dry other soft plant biomass.

본 연구는 갯버들의 생장 특성을 기반으로 단기순환벌채림(Short rotation coppices)을 조성하고, 바이오매스 생산 및 자원화 방안을 모색하기 위하여 우수집단 및 개체를 선발하고자 수행하였다. 갯버들이 서식하는 7개 집단에서 시료를 수집하여 2개의 시험지(춘천과 용인)에 집단별로 시험구를 설치하고, 우수집단 및 개체선발에 있어서 각 요인이 미치는 유의적인 차이를 조사하였다. 수고와 근원경은 시험지, 수집집단 및 연간생장 간에 통계적으로 유의한 차이를 보였다(p<0.01). 식재 3년 후 지상부의 수확량은 춘천시험지에서는 영월집단이 개체 당 평균 4.8 kg(dw)으로 나타났으며, 이는 각 집단별 전체 평균의 2배 이상의 수확량으로 보여진다. 용인시험지에서는 홍천과 원주집단의 수확량이 개체 당 평균 3.3kg(dw)으로 가장 높게 나타났다. 두 시험지에서 수확량이 높게 나타난 집단은 일치하지 않았으나 수집 집단(Pop)과 시험지(Nur) 간의 상호작용에서 유의성이 인정되어서, 각 시험지별로 수확량이 우수한 집단을 제시할 수 있었다(F value = 3.51, p<0.01). 이러한 결과를 토대로 선발된 집단의 영양계 검정을 이용하여 목질계 바이오매스 자원화를 위한 우수 자원을 육성할 수 있을 것이다.

A compressive description of tropical milky white mushroom (Calocybe indica P&C var. APK2) is provided in this review. This mushroom variety was first identified in the eastern Indian state of West Bengal and can be cultivated on a wide variety of substrates, at a high temperature range ($30{\sim}38^{\circ}C$). However, no commercial cultivation was made until 1998. Krishnamoorthy 1997 rediscovered the fungus from Tamil Nadu, India and standardized the commercial production techniques for the first time in the world. This edible mushroom has a long shelf life (5~7 days) compared to other commercially available counterparts. A comprehensive and critical review on physiological and nutritional requirements viz., pH, temperature, carbon to nitrogen ratio, best carbon source, best nitrogen source, growth period, growth promoters for mycelia biomass production; substrate preparation; spawn inoculation; different supplementation and casing requirements to increase the yield of mushrooms has been outlined. Innovative and inexpensive methods developed to commercially cultivate milky white mushrooms on different lignocellulosic biomass is also described in this review. The composition profiles of milky white mushroom, its mineral contents and non-enzymatic antioxidants are provided in comparison with button mushroom (Agaricus bisporus) and oyster mushroom (Pleurotus ostreatus). Antioxidant assay results using methanol extract of milky white mushroom has been provided along with the information about the compounds that are responsible for flavor profile both in fresh and dry mushrooms. Milky white mushroom extracts are known to have anti-hyperglycemic effect and anti-lipid peroxidation effect. The advantage of growing at elevated temperature creates newer avenues to explore milky white mushroom cultivation economically around the world, especially, in humid tropical and sub-tropical zones. Because of its incomparable productivity and shelf life to any other cultivated mushrooms in the world, milky white mushroom could play an important role in satisfying the growing market demands for edible mushrooms in the near future.
