DAMPAK PENURUNAN KADAR AIR TERHADAP RESPON FISIOLOGIS DAN BIOKIMIA PROPAGUL Rhizophora apiculata Bl.

Abstract: The research is aimed at studying effect of decreasing moisture content to the response of physiological and biochemical of Rhizophora apiculata Bl. propagules. Decreasing of moisture content is done through desiccation and storage at two (2) storage room in different temperature. Decreasing propagules moisture content by desiccation for 1, 2 and 3 weeks; storing the propagules conventionally. Completely randomized design was used with one factor for the first trial and two factors for the second trial (enviro… Show more

“…At 72 hours of drying time, -1 germinating seed was 953 pure seeds 0.1 g , germinating rate of 42.65 seeds per day, protein content of 14.4%, fat of 21%, and 44.1% of carbohydrate. According to Rohandi and Widyani (2010), declining process in seed moisture content after facing more than 72 hours drying time can cause significant decrease in seed germination. Seed moisture content is an important factor with respect to their effects on seed viability.…”

“…Periode hidup benih dalam penyimpanan dapat dipengaruhi oleh suhu lingkungan simpan atau kelembaban nisbi lingkungan simpan dan kadar air benih (Harnowo, 2006 (Rohandi & Widyani, 2010).…”

“…Laju perkecambahan hanya menunjukkan rata-rata hari berkecambah, sedangkan nilai perkcambahan menunjukkan jumlah benih berkecambah dalam persen per hari sampai akhir pengujian yang merupakan pencerminan dari daya tumbuh benih (Payung et al 2012) Selain aspek fisiologis, hasil analisis biokimia menunjukkan bahwa komposisi kandungan biokimia benih S. stenoptera meliputi kandungan pati, lemak dan protein cenderung mengalami peningkatan dan penurunan selama penyimpanan. Kondisi demikian juga terjadi pada penyimpanan propagul Rhizophora apiculata (Rohandi dan Widyani, 2010 Kandungan pati mengalami penurunan masing-masing 2,65% (ruang kamar) dan 4,32% (ruang AC). Yuniarti et al (2013) menjelaskan bahwa penurunan karbohidrat mengindikasikan terjadinya penurunan pertahanan benih yaitu penurunan viabilitas benih yang ditandai dengan penurunan daya berkecambah benih selama penyimpanan.…”

“…Kadar lemak benih S. stenoptera cukup tinggi bila dibandingkan dengan Acacia mangium yaitu 5% (Syamsuwida et al, 2002) ataupun R. apiculata sebesar 0,07% (Rohandi dan Widyani, 2010). Hal tersebut menunjukkan kecenderungan benih bersifat rekalsitran.…”
